Because once the unit displays leaks around the some of the four bolts that mend the unit together. It looses some of the cushioning pressure for the flap or valve to easily and to float in its close position.

Is it normal for this to leak from the plastic joint in the middle where it's screwed together by 4 screws? Its a slow drip coming from there; not higher from any of the rubber connections. Can I safely tighten the screws a quarter turn, glue it, or should I return it?
Asked by: Trevor
You can try to tighten. If that doesn’t work return it

Just installed this product & it makes a rapid klicking-type noise when retracting. Is this normal?

Length from coupling to coupling

I see the length is 11.75" and I assume that includes the klunkless chamber. What is the total length from the outer edge of each coupling, i.e., the length of the pipe it will be covering?
Asked by: Louietc
about 11 to 11.25

The anti clunk works, but if you have a pump that runs often be ready to replace this anti clunk check valve a couple if times a year. It literally breaks/leaks at the seam over time. I have replaced one location 3 times in the past year. I have installed at other locations that don't run so often without issues.

There is water seeping from the connection in the middle of check valve. I've tried tightening the nuts and haven't checked it since I did that to see if it helped or not.

Too small for my system, takes a 1 1/2" pipe down to 1" for the check valve and buffer. Didn't use. However, the construction and fit appear to be excellent, so I would recommend this product for folks with a 1" system.

Glentronics products (pumps, switches, check valves and batteries) are all excellent quality.. and perform perfectly.. couldn’t be happier.. this check valve completely eliminates the clunk at the end of the pump cycle..
