Customer Questions & Answers

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?

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.

I thought something was wrong with the first one because it wasn't that quiet. It still CLUNKED after the sump activated. Switched to a Zoeller, z300041. No clunk. Very Quiet.

Rated 2 out of 5 by from Klunkless - leaks at seam Leak at seam on all 4 sides upon first test, brand new, out-of-the-box. Disassembled, inspected, reassembled, still leaks. Off to the return counter.

Rated 5 out of 5 by from Very quiet check valve! Our previous check valve was incredibly loud. Not sure why we lived with it for years. I saw this product passing by the aisle at Home Depot and am so glad I purchased it. It works well, no leaking and we can't hear it when the sump pump runs. I installed it when adding a backup sump pump so the overall install was time consuming but this part was simple.

Rated 5 out of 5 by from Awesome!!!!!!!!!!! Wow, been living with a loud klunk in the basement right under my bed for years. Saw this strolling through the store and thought I would try it. I was amazed, the trickle of water coming in makes more noise than this valve. Glad I got an alarm on my sump because I will no longer know if it is working by listening for the loud klunk. Very Happy.

Rated 1 out of 5 by from Leaks and Klunks Leaks at the seem out of the box. I was able to fix the leak by tightening the four screws that hold the assemble together. However it had no effect on the water hammer. Save yourself the trouble avoid this value.

Rated 5 out of 5 by from Works! This worked for us, thank goodness! Our pump was klunking so loudly in the basement it would wake me up during the night. Almost sounded like a door slamming!
