  • Balboa Ultima 1.5HP 2x2 48 frWet End 1215123 — Get Your Hot Tub Running Again Your hot tub pump has given out. The jets are weak, water isn't circulating, or there's a leak around the seal. Before you replace the entire pump, there's a smarter fix: the Balboa Ultima 1.5HP Wet End (Part #1215123). It's one of the most reliable wet end replacements in the industry — and Western Tub and Pool has it in stock and ready to ship. Shop and order at Western Tub and Pool. [Order Now] | Call us: 1-855-248-0777 | Email: fixmytub@gmail.com What Is the Balboa Ultima 1.5HP Wet End 1215123? The wet end is the water-contact portion of your spa pump — the part that actually moves water through your jets, jets lines, and filtration system. It houses the impeller, volute, mechanical seal, and wear ring. When a wet end cracks, leaks, or seizes, you don't need to replace the entire motor. A direct wet end swap is faster, more affordable, and gets you back in the water sooner. The Balboa Ultima 1.5HP Wet End (SKU: 1215123) is an OEM-quality replacement manufactured by Balboa Water Group (BWG) — formerly branded under the Vico name. It is specifically engineered for the Ultima and Ultimax pump series and is trusted by hot tub technicians and DIY owners across North America.

Will this wet end fit my existing motor? It is compatible with 48Y frame, through-bolt style motors rated at 1.5HP, including both single-speed and dual-speed configurations. If your motor meets these specs, the 1215123 is a direct fit. Do I need to buy a new seal separately? No .The wet end includes a mechanical seal. However, you should confirm whether your pump uses the PS2136 (old style) or PS201 (new style) seal before installation to ensure compatibility. My pump part number doesn't exactly match — can I still use this wet end? Possibly. The 1215123 replaces several cross-reference numbers including 34-430-1174, 5190-250, and PKUL15SDCS2/2. If you're unsure, contact us with your pump label info and confirm compatibility before you purchase. What union do I need for this wet end? The Vico Ultima uses a proprietary 2" thread design. You'll need replacement union model 35-430-1268 (2" bt x 2"s) for a proper connection. I can't find my part number anywhere. Can you help? Absolutely. We specialize in hard-to-find spa parts.

    Frequently Asked Questions

    How do I know this wet end is the right fit for my hot tub?

    The best way to confirm compatibility is to check your existing pump's part number, which is usually found on the label affixed to the pump motor or wet end housing. You can also send us your spa's make, model, and serial number — along with photos if possible — to fixmytub@gmail.com and we'll help you find the exact match.

    What does a wet end do, and why does it need replacing?

    The wet end is the hydraulic component of your spa pump responsible for moving water. It houses the impeller and volute, which generate water flow. Over time, wear, chemical exposure, or physical damage can cause leaks, reduced flow, or complete failure. Replacing just the wet end — rather than the entire pump — is a cost-effective way to restore performance.

    Can I install this wet end myself?

    Yes, many spa owners complete this replacement themselves with basic tools. The wet end attaches to your existing motor, meaning you don't need to re-wire anything. However, if you're unsure, we recommend consulting a qualified spa technician. Feel free to call us at 1-855-248-0777 for guidance.

    What is the difference between the suffixes on your part numbers?

    Western Tub and Pool is an international e-tailer. We source parts from warehouses in multiple regions to ensure availability. To help you identify the origin of your part:

    • U suffix — Part sourced from the United States
    • C suffix — Part sourced from Canada
    • E suffix — Part sourced from Europe
    • A suffix — Part sourced from Asia

    Some parts may be available from more than one region. Regional sourcing can affect shipping times and costs. 

    How long will shipping take?

    Shipping times depend on your location and the regional warehouse fulfilling your order. We'll provide estimated delivery details at checkout. For urgent orders or international shipping inquiries, call us directly at 1-855-248-0777.

    Do you ship internationally?

    Yes. Western Tub and Pool is a proud international e-tailer. We ship to customers across North America, Europe, and beyond. Contact us to discuss your shipping options.
