“ After two years of listening to a loud clunk with every sump cycle, this solved it entirely. Highly recommend.”
“ I love this product! I can barely hear my sump pump eject water now. Nice that it included fittings and is easy to remove. Highly recommend!”
“ Well holy cow. This thing is SO QUIET. Thump thump thump is gone. Should’ve bought this earlier. Just get it — and the glue too.”
“ Our sump pump's original check valve was noisy... This new one makes no noise at all, even when standing right beside it. Would buy again!”
“ It works, but sometimes causes a gurgling noise when the sump shuts off — probably due to the room being directly above.”
“ I used rubber couplings and clamps instead of cement for easy replacement later. Works great without gluing.”
“ My sump pump was so loud it sounded like a super loud toilet flush. Not anymore! It’s super quiet now. This is the best money I’ve spent.”
“ This check valve is unbelievably quiet. I didn't realize how loud the old Zoeller was until I installed this one. Absolutely no kick when the pump shuts off — wish I’d replaced it sooner!”
