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
Check valves need a weep hole beneath the valve to allow the air to be replaced with water when the pump turns on. Without a weep hole, the pump could become airlocked because air is too compressible and not dense enough to open the valve with the weight of all the water on top of the valve.

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

Asked by: Delio
No. Same problem after a few months. Take it back for a refund. Purchase a Campbell "Quiet Check Valve" to eliminate the problem. I did.

I have a watchdog special . main pump with battery back up pump. both are connected at a Y above them with one pipe to the outside of house. there is a very loud klunk noise when pump runs and can be heard throughout the house. i want to install this but when i call the company to ask about proper installation i get different answers from each person i talk to.. each pump has a check valve threaded on to them. does this replace one of those? where does this valve get placed in the piping? my plumber suggested removing the check valve from the main pump and connecting the new one above the Y. or removing both check valves current threaded on to the pumps and installing this above the Y.. what is the right answer?
Asked by: carl

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
It measures 9 3/4" from one end of the coupling to the other.

My customer was really satisfied how it reduced the noise of water klunking. From banging to quiet, this product really wored nicely. I recommend it to any for any sump pump installation.

Rated 4 out of 5 by from Went from 5 or 6 loud clunks to one quiet clunk. I believe this product fixed our water hammer issue and now we are just hearing a faint clunk from the check valve closing. Product appears to have done it's job.

After that, the "klunk" return even a little louder. I did some research and purchased a Campbell "quiet check valve" with over 300 5 star ratings and none lower that was only $5.00 more than the above. Installation was a little more difficult but well worth the time. I have no doubt that the Campbell is the best quiet check valve on the market.

Works perfectly - the old valve sent a very loud thump that could be felt in the floor and now it's a very soft and barely noticeable. My pipe run is about 40' to the outside and is butted against joists (which is why it was felt in the floor). Thank you for a great product!

Despite its presence, I get a loud series of three thumps when the pump shuts off. It's functional as a basic check valve, but if you want something quiet, you should look elsewhere.

Now, I can sleep in peace. NOTE: install a shutoff valve above the check valve so the water doesn't run back down on you when you repair the sump pump again. Cheers
