![Relax More. Worry Less. The Automated Spa Monitor.
Stop guessing with messy test kits. The Balboa Purezone™ Hover (Part #96000) floats freely in your spa, automatically monitoring water health so you can focus on relaxing.
[Shop the Purezone Hover at Western Tub and Pool ]
Smart water care made simple
Maintaining your hot tub shouldn't feel like a chemistry experiment. The Balboa Purezone Water Monitoring System with Hover replaces manual testing with advanced optical technology, delivering precision and peace of mind.
Forget messy test kits
Say goodbye to color-matching strips and liquid reagents. Purezone automates the process, checking your water daily or every other day without you lifting a finger.
Precision optical readings
Using advanced optical sensors, Purezone measures key water parameters including pH, free chlorine, total alkalinity, and temperature. This ensures your water is safe, clean, and comfortable for every soak.
Real-time alerts & expert advice
Connected via the Purezone app (iOS and Android), the system sends alerts directly to your phone. It doesn’t just tell you the levels; it provides personalized chemical dosing recommendations tailored to your specific spa size and sanitizer type.
Floats freely with no installation
Unlike wall-mounted monitors that require drilling, the Purezone Hover (96000) simply floats in your water. It’s the perfect "drop-and-go" solution for existing hot tubs.
How it works
1. Connect the App
Download the Purezone app, create your profile, and input your spa details (size and sanitizer type) for customized advice.
2. Float and Monitor
Place the charged Purezone Hover unit into your spa water. It uses a replaceable P3 cassette to perform automated tests.
3. Get Results
Receive instant updates on your phone. If your water needs attention, the app tells you exactly what to add to balance it.
Is my hot tub compatible?
The Balboa Purezone Hover is a floating system designed to work with most residential spas and swim spas up to 2,400 gallons (9,084 Liters).
Because it floats independently and operates on a rechargeable battery, it does not require a specific Balboa control pack to function as a monitor. It is an excellent addition for owners of major spa brands, including:
Cal Spas
Marquis Spas
Master Spas
Artesian Spas
Jacuzzi
Sundance
dynasty spa
maax spa
...and many others.
Note: If you are looking for the wall-mounted version, please check for the "Dock" model (Part #97000). The Hover (Part #96000) is designed specifically for floating use.
Not sure if this is the right part?
Check your current equipment part number or consult our online catalog.

Not sure if this part fits your hot tub? The best way to confirm compatibility is to:
Check your existing part number (usually printed on the pump label)
Note your spa's make, model, and serial number
Send us a photo of the existing wet end or pump
Call us at 1-855-248-0777 or email fixmytub@gmail.com and our team will verify the fit before you order.
Frequently Asked Questions
How do I know if this wet end fits my hot tub pump?
The easiest way is to check your existing pump label for the part number. If you see 310-0140 or a reference to a 4 HP, 56-frame Waterway Viper pump with a 2.5\" intake, this is your part. If you're unsure, send us your spa's make, model, serial number, or a photo and we'll confirm for you.
What does \"factory assembled\" mean?
It means the wet end arrives fully built — the housing, impeller, and seal are all pre-fitted at the factory. You don't need to source or assemble any internal components separately.
Can I install this wet end myself?
Many spa owners with basic mechanical skills can replace a wet end at home. However, if you're not comfortable working with plumbing or electrical systems near water, we recommend consulting a qualified spa technician. Our team is also happy to walk you through the process — just give us a call.
I can't find my part number. What should I do?
No problem. Send us an email at fixmytub@gmail.com with photos of your existing pump and wet end, along with your spa's make, model, and serial number. Our experts will identify the correct part for you.

Why This Is a Hard-to-Find Part — and Why We Stock It
Pump unions take a beating. Constant pressure cycles, chemical exposure, and UV degradation cause union nuts to crack and O-rings to harden and fail over time. When that happens, water finds a way out — and a small leak can become a big problem quickly.
The challenge? This part isn't always sitting on the shelf at your local hardware store. It requires the right thread profile (buttress thread, not standard pipe thread), the right slip size, and a matching O-ring. Getting just one of these wrong means the repair won't hold.
At Western Tub and Pool, we stock the parts that are genuinely hard to find — so you don't have to wait weeks or cobble together mismatched components.
How to Install Your New Pump Union
Step 1: Turn off power and drain the pump area
Switch off the spa at the breaker and allow pressure to release before touching any plumbing connections.
Step 2: Unscrew the old union nut
Turn the union nut counterclockwise to disconnect the pump from the plumbing line. If the nut is cracked or seized, a split-nut replacement tool may be required.
Step 3: Remove the old tailpiece and O-ring
Pull the tailpiece free from the pump port. Inspect and discard the old O-ring — never reuse a compressed or damaged O-ring.
Step 4: Install the new tailpiece and O-ring
Insert the new tailpiece into the pump port. Seat the new O-ring into its groove, applying a small amount of silicone lubricant for a better seal.
Step 5: Thread on the union nut and tighten
Hand-tighten the new union nut onto the buttress threads, then snug it with a strap wrench — do not over-torque. Restore power and check for leaks.

Frequently Asked Questions
How do I know if this is the right union for my spa?
The best way to confirm is to check the part number printed or stamped on your existing union nut or tailpiece. Common numbers for this configuration include 415-6000 (nut) and 417-5970 (tailpiece). If your part number isn't visible, send us a photo along with your spa's make, model, and serial number and we'll identify it for you. Email fixmytub@gmail.com or call 1-855-248-0777.
Does this kit include the O-ring?
Yes. This listing includes the union nut, S tailpiece, and O-ring — all three components needed for a complete pump union assembly.
What is a buttress thread, and does it matter?
Yes, it matters. Buttress thread is a specialized thread profile used on spa pump unions — it is not interchangeable with standard NPT (pipe thread) fittings. Using the wrong thread type will result in cross-threading or a failed seal. This kit uses the correct 2-1/2" female buttress thread (FBT) profile.
My union nut is cracked and difficult to access. Can it still be replaced?
If your existing nut is cracked but still attached, a split-nut design may allow you to replace it without cutting the plumbing. We carry those as well — ask us about the right option for your situation.
Can I use this part on a heater union?
No. This tailpiece is designed for pump union connections and uses a small flange suited to pump ports. Heater unions use a different tailpiece profile. If you need a heater union, contact us and we'll point you to the correct part.
Do you offer help identifying parts I can't find elsewhere?
Absolutely. Hard-to-find parts are our specialty. Send us a photo of the part, your spa's serial number, or any part numbers you can find, and our team will track down what you need. Email fixmytub@gmail.com or browse our online catalogue.

When you need to service your pump, simply unscrew the union nut — no cutting required

Frequently Asked Questions
How do I know if this is the correct pump union for my hot tub?
The best way to confirm compatibility is to check the existing union on your pump. Measure the outside diameter of your pump's wet end threads — if it measures approximately 3 5/8" across, this union is likely the correct fit. You can also check the stamped part number on your existing union, or call us at 1-855-248-0777 and we'll help you confirm.
Can I send you photos of my part to confirm the fit?
Absolutely. Email clear photos of your existing union, along with your hot tub's make, model, and serial number, to fixmytub@gmail.com. Our team will review your images and confirm whether this part is the right match before you order.
Is the gasket included, or do I need to order it separately?
The gasket is included with this union. You will not need to purchase it separately.
Do I need special tools to replace a pump union?
In most cases, no. Pump unions are designed for hand-tightening and removal. You may need basic plumbing supplies such as PVC primer and cement if you are also replacing the tailpiece or re-gluing the slip side into new pipe.
What if I can't find my part number?
That's what we're here for. Send us an email to fixmytub@gmail.com with your hot tub's make, model, and serial number, along with photos of the part you need. We'll identify the correct replacement and get back to you promptly.
Do you carry other Waterway pump parts?
Yes. We carry a wide range of Waterway pump components, including wet ends, impellers, O-rings, seals, and more. Browse our online catalogue or give us a call to check availability.

Please note: This cord ships with the AMP pins and connector separated. This allows you to place the pins in the correct order to match your specific spa controller, as different manufacturers use different pin and color configurations. If you are unsure how to configure your cord, call us at 1-855-248-0777 — we are happy to walk you through it.
Why This is the Right Cord for Your Spa Pump
Industry-Standard 4-Pin AMP Connector
The 4-pin AMP (MP-style) male plug is the industry standard for 2-speed spa pump power cords. This means it is compatible with a wide range of hot tub brands and control systems right out of the box.
Extra Length for Easy Installation
At 8 full feet (96 inches), this cord gives you the flexibility you need to route the cable cleanly through your spa cabinet without straining connections or compromising safety. Shorter cords — like the common 48" versions — simply do not reach in many configurations.
14/4 AWG Heavy-Duty Wiring
Built with 14-gauge, 4-wire construction (Black, Red, White, Green), this cord is rated for the current demands of 2-speed spa pumps across both 115V and 230V systems.
Works with 1-Speed Pumps Too
If you have a single-speed pump that uses a 4-pin AMP connector, this cord will work — simply eliminate one wire from the configuration.
Compatible Hot Tub Brands and Pump Systems
This 8-foot, 4-pin AMP pump power cord is used across a wide range of hot tub brands and spa control systems, including pumps and controls from:
Aqua-Flo (FMHP, FMCP, XP2 series — 115V and 230V 2-speed pumps)
Waterway Plastics (2-speed pump models using AMP connectors)
Caldera Spas (2002 and above, using Advent Control Box)
Marquis Spas (2-speed pump configurations)
Cal Spas (2-speed pump models)
DreamMaker / AquaRest Spas (2-speed pump configurations)
Artesian Spas (2-speed pump models)
Jacuzzi / Sundance Spas (select 2-speed pump models)
Master Spas (select 2-speed pump configurations)
Coleman / Maax Spas (2-speed pump models)
Dimension One Spas (select models)
Dynasty Spas (select models)
Vita Spas (select models)

Not sure if this cord fits your pump? Check your existing part number, or send us your hot tub's make, model, and serial number — and a photo of the existing cord — and our team will confirm compatibility before you order. Email us at fixmytub@gmail.com.
How to Identify Your Pump Power Cord
Before ordering, here are a few quick checks to confirm this is the right cord for your spa:
1. Count the Pins
Look at the connector on your existing pump cord. A 2-speed pump cord uses a 4-pin AMP connector. A 1-speed pump uses a 3-pin connector. If yours has 4 pins, this cord will work.
2. Check the Wire Colors
A standard 4-wire, 2-speed AMP pump cord contains four wires: Black, Red, White, and Green. If your existing cord matches this color configuration, you have a standard 2-speed AMP cord.
3. Measure the Cord Length
If your current cord is frayed, burned, or damaged at the pump end, measure from the control box to the pump to confirm that 8 feet is the right length for your installation. We also carry 48-inch (4 ft) and 72-inch (6 ft) versions — call us if you need a different length.
4. Check Your Part Number
Common cross-reference part numbers for this cord include:
30-0326-96 (8-foot AMP 2-speed cord)
30-1001A (72-inch version)
741-CGGG-45X (48-inch version, also used in NEO 2100 kit)
Frequently Asked Questions
Is this cord compatible with my spa if I don't know the part number?
Yes — in many cases. If your spa uses a 2-speed pump with a 4-pin AMP-style connector, this cord is likely compatible. The safest approach is to send us your spa's make, model, and serial number, along with a photo of the existing cord and connector, and we will confirm the fit. Email us at fixmytub@gmail.com or call 1-855-248-0777.
Why does this cord ship with the pins separated?
Different spa control manufacturers wire their AMP connectors in different pin-color sequences. By shipping the cord with the pins loose, you can arrange them to match your specific controller's configuration exactly. If this sounds complicated, don't worry — our team can guide you through it over the phone.
Can I use this cord on a 1-speed pump?
Yes. Single-speed pumps that use a 4-pin AMP connector can use this cord — simply leave one wire out of the connector. Alternatively, we carry a dedicated 1-speed pump cord if you prefer a clean, exact fit.
What if I order the wrong cord?
Contact us immediately at fixmytub@gmail.com or 1-855-248-0777 and we will help sort it out. We stock a wide range of cord lengths and configurations, so there is a good chance we can swap you into the right part quickly.
Do you offer help identifying other hard-to-find spa parts?
Absolutely. Western Tub and Pool specializes in replacement hot tub and spa parts, including hard-to-find components.

Please note: This cord ships with the AMP pins and connector separated. This allows you to place the pins in the correct order to match your specific spa controller, as different manufacturers use different pin and color configurations. If you are unsure how to configure your cord, call us at 1-855-248-0777 — we are happy to walk you through it.
Why This is the Right Cord for Your Spa Pump
Industry-Standard 4-Pin AMP Connector
The 4-pin AMP (MP-style) male plug is the industry standard for 2-speed spa pump power cords. This means it is compatible with a wide range of hot tub brands and control systems right out of the box.
Extra Length for Easy Installation
At 8 full feet (96 inches), this cord gives you the flexibility you need to route the cable cleanly through your spa cabinet without straining connections or compromising safety. Shorter cords — like the common 48\" versions — simply do not reach in many configurations.
14/4 AWG Heavy-Duty Wiring
Built with 14-gauge, 4-wire construction (Black, Red, White, Green), this cord is rated for the current demands of 2-speed spa pumps across both 115V and 230V systems.
Works with 1-Speed Pumps Too
If you have a single-speed pump that uses a 4-pin AMP connector, this cord will work — simply eliminate one wire from the configuration.
Compatible Hot Tub Brands and Pump Systems
This 8-foot, 4-pin AMP pump power cord is used across a wide range of hot tub brands and spa control systems, including pumps and controls from:
Aqua-Flo (FMHP, FMCP, XP2 series — 115V and 230V 2-speed pumps)
Waterway Plastics (2-speed pump models using AMP connectors)
Caldera Spas (2002 and above, using Advent Control Box)
Marquis Spas (2-speed pump configurations)
Cal Spas (2-speed pump models)
DreamMaker / AquaRest Spas (2-speed pump configurations)
Artesian Spas (2-speed pump models)
Jacuzzi / Sundance Spas (select 2-speed pump models)
Master Spas (select 2-speed pump configurations)
Coleman / Maax Spas (2-speed pump models)
Dimension One Spas (select models)
Dynasty Spas (select models)
Vita Spas (select models)
NEO 2100 Control Kit (w/Retro Kit 780-8020, ref. p/n 741-CGGG-45X)
Not sure if this cord fits your pump? Check your existing part number, or send us your hot tub's make, model, and serial number — and a photo of the existing cord — and our team will confirm compatibility before you order. Email us at fixmytub@gmail.com.
How to Identify Your Pump Power Cord
Before ordering, here are a few quick checks to confirm this is the right cord for your spa:
1. Count the Pins
Look at the connector on your existing pump cord. A 2-speed pump cord uses a 4-pin AMP connector. A 1-speed pump uses a 3-pin connector. If yours has 4 pins, this cord will work.
2. Check the Wire Colors
A standard 4-wire, 2-speed AMP pump cord contains four wires: Black, Red, White, and Green. If your existing cord matches this color configuration, you have a standard 2-speed AMP cord.
3. Measure the Cord Length
If your current cord is frayed, burned, or damaged at the pump end, measure from the control box to the pump to confirm that 8 feet is the right length for your installation. We also carry 48-inch (4 ft) and 72-inch (6 ft) versions — call us if you need a different length.
4. Check Your Part Number
Common cross-reference part numbers for this cord include:
30-0326-96 (8-foot AMP 2-speed cord)
30-1001A (72-inch version)
741-CGGG-45X (48-inch version, also used in NEO 2100 kit)
Frequently Asked Questions
Is this cord compatible with my spa if I don't know the part number?
Yes — in many cases. If your spa uses a 2-speed pump with a 4-pin AMP-style connector, this cord is likely compatible. The safest approach is to send us your spa's make, model, and serial number, along with a photo of the existing cord and connector, and we will confirm the fit. Email us at fixmytub@gmail.com or call 1-855-248-0777.
Why does this cord ship with the pins separated?
Different spa control manufacturers wire their AMP connectors in different pin-color sequences. By shipping the cord with the pins loose, you can arrange them to match your specific controller's configuration exactly. If this sounds complicated, don't worry — our team can guide you through it over the phone.
Can I use this cord on a 1-speed pump?
Yes. Single-speed pumps that use a 4-pin AMP connector can use this cord — simply leave one wire out of the connector. Alternatively, we carry a dedicated 1-speed pump cord if you prefer a clean, exact fit.
What if I order the wrong cord?
Contact us immediately at fixmytub@gmail.com or 1-855-248-0777 and we will help sort it out. We stock a wide range of cord lengths and configurations, so there is a good chance we can swap you into the right part quickly.
Do you offer help identifying other hard-to-find spa parts?
Absolutely. Western Tub and Pool specializes in replacement hot tub and spa parts, including hard-to-find components. If you cannot find what you need in our online catalogue, send us an email with your part number (if known), photos, and your spa's make, model, and serial number — and we will do the legwork for you.

Yes. The 14/4 AWG wire gauge and 4-pin AMP connector in this cord are compatible with both 115V and 230V 2-speed spa pump installations.

Is your hot tub blower failing to produce bubbles, running too loud, or not turning on at all? Western Tub and Pool carries quality replacement spa air blowers to get your tub back to full performance — fast.

[Shop and Order at Western Tub and Pool]
What Is a Spa Air Blower — and Why Does It Matter?
A spa air blower (also called an air pump or bubbler) pushes pressurized air through your hot tub's dedicated air jets, creating those soothing, therapeutic bubbles that make a soak truly relaxing. Without a functioning blower, you lose that massaging bubble action entirely.
When your air blower starts to fail, you will typically notice:
Little to no air bubbles from your air jets
Unusual humming, rattling, or grinding noises
The blower running but producing no airflow
The unit failing to turn on at all
Replacing a worn or failed blower is one of the most common hot tub repairs — and one of the most straightforward, especially with the right part and a little guidance from our team.

Frequently Asked Questions
How do I know which air blower fits my hot tub?
The most reliable method is to locate the label on your existing blower and note the part number, voltage (120V or 230V/240V), amperage, and plumbing connection size (1.5" or 2"). You can also check your hot tub's owner manual or look up the serial number. If you are still unsure, send us the make, model, serial number, and a photo of the existing unit to fixmytub@gmail.com and we will identify the right replacement for you.
What if I cannot find the part number on my blower?
No problem. Send us clear photos of the existing blower, including any visible labels, the plug/connector type, and your hot tub's make and model. Our parts specialists will do the research for you. Email fixmytub@gmail.com or call 1-855-248-0777.
What voltage do most hot tub air blowers run on?
Most residential hot tub blowers operate on either 120V or 230V/240V. It is critical that your replacement blower matches the voltage of your existing unit and control system. Using the wrong voltage can damage your spa's electronics.
What is the difference between an air blower and a jet pump?
A jet pump (circulation pump) circulates heated water through your spa's water jets. An air blower pushes pressurized air through separate air jets or air channels to create bubbles. They are entirely separate components and are not interchangeable.
Can I install a replacement air blower myself?
Many homeowners complete this replacement themselves, especially when the blower uses a plug-in connection. However, hardwired units should be installed by a licensed electrician. If you need guidance, our team is happy to walk you through the process — just give us a call.
Do your replacement blowers come with a warranty?
Warranty coverage varies by brand and model. Many of the blowers we carry are backed by manufacturer warranties ranging from 1 year and beyond. Contact us for warranty details on a specific unit.
How long does shipping take?
Shipping timelines depend on your location and part availability. Contact us directly for the most up-to-date stock and shipping information: 1-855-248-0777 or fixmytub@gmail.com.

What Is a Spa Air Blower — and Why Does It Matter?
A spa air blower (also called an air pump or bubbler) pushes pressurized air through your hot tub's dedicated air jets, creating those soothing, therapeutic bubbles that make a soak truly relaxing. Without a functioning blower, you lose that massaging bubble action entirely.
When your air blower starts to fail, you will typically notice:
Little to no air bubbles from your air jets
Unusual humming, rattling, or grinding noises
The blower running but producing no airflow
The unit failing to turn on at all
Replacing a worn or failed blower is one of the most common hot tub repairs — and one of the most straightforward, especially with the right part and a little guidance from our team.
Spa Air Blowers Available at Western Tub and Pool
We carry a range of spa air blowers to suit different hot tub systems, voltages, and plumbing configurations. Whether you need a direct OEM-style replacement or a compatible aftermarket unit, we can help you find the right match.

Frequently Asked Questions
How do I know which air blower fits my hot tub?
The most reliable method is to locate the label on your existing blower and note the part number, voltage (120V or 230V/240V), amperage, and plumbing connection size (1.5\" or 2\"). You can also check your hot tub's owner manual or look up the serial number. If you are still unsure, send us the make, model, serial number, and a photo of the existing unit to fixmytub@gmail.com and we will identify the right replacement for you.
What if I cannot find the part number on my blower?
No problem. Send us clear photos of the existing blower, including any visible labels, the plug/connector type, and your hot tub's make and model. Our parts specialists will do the research for you. Email fixmytub@gmail.com or call 1-855-248-0777.
What voltage do most hot tub air blowers run on?
Most residential hot tub blowers operate on either 120V or 230V/240V. It is critical that your replacement blower matches the voltage of your existing unit and control system. Using the wrong voltage can damage your spa's electronics.
What is the difference between an air blower and a jet pump?
A jet pump (circulation pump) circulates heated water through your spa's water jets. An air blower pushes pressurized air through separate air jets or air channels to create bubbles. They are entirely separate components and are not interchangeable.
Can I install a replacement air blower myself?
Many homeowners complete this replacement themselves, especially when the blower uses a plug-in connection. However, hardwired units should be installed by a licensed electrician. If you need guidance, our team is happy to walk you through the process — just give us a call.
Do your replacement blowers come with a warranty?
Warranty coverage varies by brand and model. Many of the blowers we carry are backed by manufacturer warranties ranging from 1 year and beyond. Contact us for warranty details on a specific unit.
How long does shipping take?
Shipping timelines depend on your location and part availability. Contact us directly for the most up-to-date stock and shipping information: 1-855-248-0777 or fixmytub@gmail.com.
Can't Find Your Part? We Can Help.
Tracking down the right spa blower for an older or less common hot tub model can be frustrating. That is exactly what we are here for.

Your hot tub's make, model, and serial number

Email: fixmytub@gmail.com | Phone: 1-855-248-0777
Frequently Asked Questions
How do I know if this pump will fit my hot tub?
The best way to confirm compatibility is to match your existing pump's part number, frame size (56Y), voltage (230V), amperage (12A), and union connection size (2" MBT). If you're unsure, take a photo of your existing pump's label and send it to fixmytub@gmail.com. Our team will identify the part and confirm the correct replacement.
Does this pump come with everything I need to install it?
The pump includes unions and cord O-rings, which cover most of what you need for a standard swap-out. However, it does NOT include a pump power cord. If your existing cord is not compatible, we can help you source the correct 4-wire AMP connector cord. Check our online catalogue or call 1-855-248-0777.
Can I use this pump as a single-speed pump?
Yes. The LX 56WUA400-II can be wired as either a single-speed or dual-speed pump, depending on your control system. Wiring diagrams for both configurations are available — contact us for guidance.
Is this the right pump for Jacuzzi or Sundance spas with a sliding/clamp base?
No. This version has a permanently welded steel mounting bracket and is NOT compatible with the patented moveable clamp-on base used by some Jacuzzi and Sundance models. If your existing pump has a clamp-style external base, you need the no-base version (56WUA400-II NF). Contact us to confirm which version suits your spa.
My pump is labeled 6HP — is this still the right pump?
Possibly, yes. The LX 56WUA400-II is sometimes relabeled by hot tub manufacturers as 5HP, 6HP, or even 7HP, but the underlying motor is the same: 12 amps at 230 volts (2,760 watts). The sticker does not change the pump's performance. Check your amperage rating — if it reads 12A at 230V, this pump is your match.
I can't find my part number — can you still help?
Absolutely. We specialize in hard-to-find parts. Send us an email at fixmytub@gmail.com with your hot tub's make, model, serial number, and a photo of the existing pump label, and we'll track down the right part for you.

Frequently Asked Questions
How do I know if this pump will fit my hot tub?
The LX 56WUA400-II fits most hot tubs that use a 56-frame, 2-speed, 4HP pump with 2" MBT plumbing connections and a 230V / 60Hz electrical system. If you're unsure, check your existing pump's label or send us your spa's make, model, and serial number at fixmytub@gmail.com — we'll confirm the fit before you order.
What does "2-speed" mean, and why does it matter?
A 2-speed pump runs at low speed for quiet, energy-efficient water filtration and circulation, and switches to high speed for jet therapy. This setup uses significantly less electricity than running a single-speed pump continuously, reducing your monthly energy costs.
Can I install this pump myself?
Many experienced spa owners replace their own pumps. However, because this involves both plumbing and electrical connections, we recommend consulting a qualified spa technician if you're unsure. Western Tub and Pool also offers in-home assistance — call us to find out more.
What is the warranty on this pump?
Warranty terms vary. Please contact us at 1-855-248-0777 or fixmytub@gmail.com for warranty details specific to your purchase.
Do you carry other spa parts and accessories?
Yes. Western Tub and Pool carries a wide range of hot tub repair and replacement parts, including heaters, control systems, filters, jets, and more. Browse our full catalogue online or give us a call — we're happy to help.
Does Western Tub and Pool offer water care support?

A failing pump doesn't just mean cold water — it means no jets, no circulation, and a spa that's out of commission. The LX 56WUA400-II is one of the most widely used replacement pumps in the industry, designed to restore full performance quickly and affordably.
Energy-Efficient 2-Speed Operation
Run on low speed for quiet, continuous water circulation — and switch to high speed when it's time for a full-pressure jet experience. Two speeds mean lower energy bills without sacrificing performance.
Powerful 4HP Motor
The 56-frame motor delivers consistent, high-volume water flow to keep your jets running at full pressure. Built with quality copper windings for cooler operation and longer motor life.
Direct Drop-In Replacement
With 2\" MBT (male bark thread) inlet and outlet connections and a standard 56-frame footprint, this pump is engineered to replace a wide range of OEM spa pumps with minimal modification.
UL & ETL Certified
Safety-certified for residential spa use in North America. Rated for 220–240V / 60Hz electrical systems.

Frequently Asked Questions
How do I know if this pump will fit my hot tub?
The LX 56WUA400-II fits most hot tubs that use a 56-frame, 2-speed, 4HP pump with 2\" MBT plumbing connections and a 230V / 60Hz electrical system. If you're unsure, check your existing pump's label or send us your spa's make, model, and serial number at fixmytub@gmail.com — we'll confirm the fit before you order.
What does \"2-speed\" mean, and why does it matter?
A 2-speed pump runs at low speed for quiet, energy-efficient water filtration and circulation, and switches to high speed for jet therapy. This setup uses significantly less electricity than running a single-speed pump continuously, reducing your monthly energy costs.
Can I install this pump myself?
Many experienced spa owners replace their own pumps. However, because this involves both plumbing and electrical connections, we recommend consulting a qualified spa technician if you're unsure. Western Tub and Pool also offers in-home assistance — call us to find out more.
What is the warranty on this pump?
Warranty terms vary. Please contact us at 1-855-248-0777 or fixmytub@gmail.com for warranty details specific to your purchase.
Do you carry other spa parts and accessories?
Yes. Western Tub and Pool carries a wide range of hot tub repair and replacement parts, including heaters, control systems, filters, jets, and more. Browse our full catalogue online or give us a call — we're happy to help.
