“Instead using cement to glue the PVC, I used rubber couplings and clamps to connect. It fits and work without cement. It will be easy to replace in the future.”
“Who Knew??? So glad I found this...had no idea what a check valve was until moving into this 120 year old house and hearing the slam every time the sump ran. Found this on youtube...easy peazy...problem solved.”
“Simply amazing. The difference between this check valve and the previous one is huge. Absolutely no clunk sound at all. Some reviews here say these stop working after a while so we will see but for now... spectacular”
“I bought this item because of recommendations that it was quite eliminating water backflow hammering. It is so true. Easy to install and works beautifully. Love it.”
