Frequently asked questions
Why is my hot tub pump union leaking?
Simple leaks at the pump or pack unions are often caused by a union that is not snug, a gasket that is no longer in good shape, or cross-threading. We recommend verifying that the union is hand-tightened. If tightening fails to resolve the issue, inspect the gasket and replace it if it shows signs of wear.
What size gasket do I need for a 2-inch pump union?
Standard 2-inch hot tub plumbing unions typically require an o-ring that is 1/8 inch thick with an inner diameter of 2 3/8 inches. Unlike flat heater gaskets, these thin, rounded o-rings fit perfectly inside the pump connectors. If you are unsure what size you need, contact us for sizing assistance.
How do I bleed air from my pump after replacing the seal?
After installing your new union and gasket, loosen the pressure union on top of the pump slightly by hand or with a strap wrench. You may hear a hissing sound or see bubbles. Once a solid stream of water appears, hand-tighten the union securely, turn the breaker on, and set the pump on high speed.
When should I replace my pump union o-rings?
You should replace your pump union o-rings any time the pump is replaced, removed for service, or if you drain the tub for winterization. Fresh seals guarantee a leak-proof connection when you start your system back up.
