![Waterway Executive Wet End — 48 Frame, 1.5 HP, 2" Intake (Part #310-1880)
Need to get your hot tub's pump running again? The Waterway Executive Wet End is one of the most trusted replacement parts in the spa industry — and Western Tub and Pool has it ready to ship.

What Is a Wet End — and Why Does Yours Matter?
The wet end is the heart of your hot tub's pump system. It houses the impeller, seal, volute, and faceplate — the components responsible for moving water through your spa. When a wet end fails, your jets stop working, your water stops circulating, and your hot tub becomes an expensive bathtub.
Replacing just the wet end (rather than the entire pump) is a cost-effective repair that restores full performance without the expense of a complete pump replacement.

Frequently Asked Questions
What is the difference between a wet end and a full pump?
A pump consists of two main parts: the motor (dry end) and the wet end. The wet end contains all the water-side components — the impeller, volute, seal, and faceplate. If your motor still runs but water flow is poor or absent, replacing just the wet end is often all you need.
How do I know if my wet end needs to be replaced?
Common signs include reduced jet pressure, unusual grinding or rattling sounds from the pump, visible water leaking around the pump housing, or a motor that runs but produces no water flow.
Will this wet end fit my motor?
This wet end is designed for 48-frame motors. As long as your existing motor is a standard 48-frame configuration and is compatible with a 1.5 HP wet end, this part will mount directly. If you're unsure, call us or send photos and we'll help you verify.
Can I install this myself?
Yes. Wet end replacement is a manageable DIY repair for most hot tub owners. The wet end simply bolts onto the motor face. Always disconnect power before beginning any repair and follow your pump's service manual.
What if I can't find my part number?
No problem. Email us a photo of your existing pump along with your hot tub's make, model, and serial number. Our team at Western Tub and Pool will identify the correct part for you at no charge.
Do you carry other Waterway Executive wet ends?
Yes. We stock multiple HP ratings and frame configurations in the Waterway Executive series, including 1.0 HP, 2.0 HP, 3.0 HP, and 4.0 HP options. Contact us for availability.

What Is a Wet End — and Why Does Yours Matter?
The wet end is the heart of your hot tub's pump system. It houses the impeller, seal, volute, and faceplate — the components responsible for moving water through your spa. When a wet end fails, your jets stop working, your water stops circulating, and your hot tub becomes an expensive bathtub.
Replacing just the wet end (rather than the entire pump) is a cost-effective repair that restores full performance without the expense of a complete pump replacement.

Is This the Right Wet End for Your Hot Tub?
The Waterway Executive 48-Frame Wet End (Part #310-1880) is used across a wide range of hot tub and spa brands. It is commonly found in spas equipped with Waterway Executive 48-frame pump systems, including models from many major manufacturers.
Not sure if this is your part? Here's what to check:
Look for the part number printed on the existing wet end housing
Check the label on your pump motor for frame size (48-frame) and HP rating (1.5 HP)
Measure the outside diameter of your intake union — it should measure approximately 3\" OD
Confirm the faceplate diameter measures 7-1/2\" across the front
Still not sure? Send us your hot tub's make, model, serial number, or a photo of your existing pump and we'll confirm compatibility before you order.
Frequently Asked Questions
What is the difference between a wet end and a full pump?
A pump consists of two main parts: the motor (dry end) and the wet end. The wet end contains all the water-side components — the impeller, volute, seal, and faceplate. If your motor still runs but water flow is poor or absent, replacing just the wet end is often all you need.
How do I know if my wet end needs to be replaced?
Common signs include reduced jet pressure, unusual grinding or rattling sounds from the pump, visible water leaking around the pump housing, or a motor that runs but produces no water flow.
Will this wet end fit my motor?
This wet end is designed for 48-frame motors. As long as your existing motor is a standard 48-frame configuration and is compatible with a 1.5 HP wet end, this part will mount directly. If you're unsure, call us or send photos and we'll help you verify.
Can I install this myself?
Yes. Wet end replacement is a manageable DIY repair for most hot tub owners. The wet end simply bolts onto the motor face. Always disconnect power before beginning any repair and follow your pump's service manual.
What if I can't find my part number?
No problem. Email us a photo of your existing pump along with your hot tub's make, model, and serial number. Our team at Western Tub and Pool will identify the correct part for you at no charge.
Do you carry other Waterway Executive wet ends?
Yes. We stock multiple HP ratings and frame configurations in the Waterway Executive series, including 1.0 HP, 2.0 HP, 3.0 HP, and 4.0 HP options. Contact us for availability.
