What pipes do you have? Buy a better quality valve. I've had it for a few years now and all is well. Periodically you need to clean it, so it must be in an accessible place. The master installers from Pom Waterproofing helped me choose a good quality valve https://pomwaterproofing.ca/back-wat...-installation/. They also do maintenance. It’s just easier for me to entrust the work to the masters and pay money than to suffer myself.
