When To Use This
Pro Tip
Always apply a light film of non-petroleum, silicone-based pool lubricant to the union O-rings during installation to prevent pinching, extend gasket life, and ensure a tight vacuum seal.
Common Questions & Instructions
What pumps are compatible with the Hayward SPX3200UNKIT union kit?
The SPX3200UNKIT is engineered specifically for Hayward TriStar (SP3200, SP3200VSP, TriStar VS) and EcoStar (SP3400VSP) pump models with standard 2-inch by 2.5-inch factory ports.
Should I use tools or pliers to tighten the union connector nuts?
No. Union nuts should always be hand-tightened only. Using channel locks or pipe wrenches can crack the composite plastic collar or pinch the internal O-ring, causing persistent leaks.
What symptoms indicate my TriStar pump unions need replacement?
Common indicators include visible water dripping at the discharge union when running, air bubbles entering the pump basket from the suction union, or hairline cracks on the threaded union nuts.
