4 Questions
Q: can this be mounted horizontally? by Frank from New Jersey on December 29, 2011
A: It’s not the best way. It really depends on the amount of head they you have above the check valve on the vertical run but it’s still going to be prone to leaking. The KCV check valve isn’t spring loaded so the only thing that will keep the valve closed is the water above it so if it’s horizontal, it’s possible that the water won’t keep it shut and therefore cause it to leak. Sometimes it does work but usually it’ll be intermittent. by Jim, Product Expert
Q: Can this be used with a Zoeller M53 sump pump? by Anonymous from Michigan on March 04, 2011
A: Yes, as long as it's a 1 1/2" discharge, which is the same size as the Zoeller M53. by Jim, Product Expert
Q: If I got three (3) of the "Klunkless Check Vavles", could I put one on my sewage line, one on the main pump and one on my backup pump? by TONY DUFFIE from Indiana on January 09, 2011
A: This valve is perfect to use on your sump lines because it can accommodate up to 1-1/2" discharge pipes.
For sewage pumps, this check valve will not work because sewage discharge pipes are 2" or larger. by Jim, Product Expert
Q: HI Jim, Can you tell me if I can use the Klunkless check valve with a sewage pump? by Ruben from Illinois on January 07, 2011
A: This check valve can't be used with sewage pumps. The maximum size pipe this valve can handle is 1-1/2".
Sewage pumps have a 2" or larger discharge. by Jim, Product Expert

Great
Everything is great about these two items. Plus it arrived within 2 days. The pump and check valve are super quiet.
My setup is for a basement laundry tub and small bar sink. I also have a water softner that drains into it and a septic system.
I also added the small bleed hole as you suggested and although I never had this before (35 years) with previous pumps it makes sense. I use to get bad odors from sump area but so far nothing.
It must be the check valve and/or the bleed hole helped.
But my cheap Wayne plastic pump was still working after 10 years but I feel this new combination is great. Worth the price.

Ron,
Thank you for your review of the Klunkless Check Valve. We appreciate your detailed feedback and satisfaction with our products.
Ordered a new zoeller m53 sump pump and basement watchdog klunkless check valve. First valve had crack in housing which I didn't notice until after installation. So I emailed service and they sent me a new one free of charge which I received the next day, and didn't even have to return ship the bad one. That is what I call customer service!!!
Will order another one from sump pumps direct , when my secondary pump dies. But this valve is awesome, it makes absolutely no noise when pump shuts down, not like the old type that sounded like an intruder busting down my front door every few minutes! Pump Is quiet and powerful, look forward to many years of service!

Dan,
Thank you so much for your feedback. We really appreciate it.
This leaked from the middle section of where the valve is located where the 4 machine screws attach the upper and lower housing. Two of the screws were somewhat loose and I took a chance on continually tightening them while being cautious of cracking the plastic. The leak finally did stop but for piece of mind, I will be replacing it with a different brand.

We do want to let you know that we stand behind our products and we would love to assist you. Please contact us directly for support at 800.991.0466 ext. 3 for technical support
Bought this after the boot on my normal check valve failed.
Installation was very easy with the rubber boots.
Tested it after install and the unit leaks at the junction of the two halves. Water began weeping out of it within seconds.
Doesn't matter how easy it is to install or how quiet it is if it's going to leak.
I purchased a different design and am happy with it.
Pros:Quiet, Easy To Use
Cons:Low Quality, Unreliable, Durability

Did not have 4 KVC 6 months, and they leaked, were loud, and 2 of them had the rubber wear out. Would not buy again.
