“I’ve used other valves and after a few months be used 30 times a day, they start chattering... The valve is 5 months old and quite as day one, worth the cost.”
“I live in a relatively new home that I love but for the fact that I can hear the sump running from just about any room in the house... For roughly $30, don't you think plumbers would offer this as an upgrade?”
“Best quiet check valve. Used by my plumbing service. A little pricey, but worth it. It's threaded on both ends, so disconnection is easy. Great for access into the sump pit. NOTHING leaks. I've had two in the basement for 10 years and just now replaced one. Very easy DIY with screw-on connectors.”
