Review on 💧 Watts Premier 560018 GPD Membrane - The Ultimate Water Filtration Solution by Flavio Scarola

Have Bought this membrane and sent it back for replacement. The replacement was bad too. In both cases, the check valve was not working properly (this is a valve built into the diaphragm that blocks flow when the tank is full). In fact, pieces of the check valve literally fell out of the first diaphragm when I removed it to send it back to Revain. I installed the replacement diaphragm sent by Revain and it worked on the initial setup and after flushing the first 3 gallons as recommended it never stopped working. When I turn off the water supply, the 3-gallon tank empties, which Watts customer service says is a sign that the check valve isn't working. I'm bringing it back again and just going with a brand new system now. Revain will not send a replacement a second time and I'm not sure I can get a working replacement.
