Poolaroo Pro Tip
When replacing your union kit, inspect the union O-rings at the same time they are the most common source of a weeping union connection. If the O-rings show any cracking, flattening, or deformation, replace them before reassembling. Hand-tighten the union nuts only; over-tightening can crack the union body. If you’re servicing a SuperFlo VS, SuperFlo VST, or SuperMax VS variable speed pump, note that Pentair documentation specifies 2 kits for a complete installation confirm your quantity before ordering.
