40mm PVC Union pliers

[Paul Jones]

garage nut,

That is a useful solution for the pool union joints. During the last 20+ years I have maintained our pool systems and over time installed union joints for our three pumps and DE filter connections. Every few years I had to replace the union joint O-rings in the joint sealing surfaces to maintain an absolute suction seal but having the unions makes all repairs very simple. It makes taking apart the system so much simpler than breaking and replacing the PVC joints. I use a very large pair of Channellock pliers to loosen the union joints but have chewed-up too many of the union outer rings and think your solution is much better.

Thanks for the posting.
