Dad didn't like it as it was always turning on and off. He ended up putting a tiny pressure tank in line, this evened out the knocking of turning the faucet off abruptly. This way the pump ran a few seconds longer to fill the pressure tank, and didn't start for a few seconds after you turned the water on (till pressure bled off the tank). He got this system for well under $50 at an RV dealership. The service guys recommended this as it increases the longevity of the pump JonR |
