I initially installed this in a 6-foot run of pipe that was only secured at the ends of the 6-foot run. When it was under 60 PSI of pressure, I bumped the check valve with a medium force and the union broke free of the threads, leaking water. I re-secured the pipe much closer to the unions and it fixed the problem. It appears that the union threads are too shallow.

Perfect Match!
The spa area of my pool would always drain down to the level of my pool everyday. I finally researched why this was happening and ordered this check valve. Fixed the issue immediately!
