So, I install this puppy, check everything 3 times, turn the water on - all is well. Then I lift the float to test the water shutting off, and the check valve is leaking all over the place........ ( membrane end) Any ideas? I can not run it w/o the check valve since I had to cut the line to install the check valve and I do not have a complete line w/o the check valve ( no fittings). I would think that if the ASO was working, there would be very little/if any pressure on the check valve.......... Spectrapure and I are not best of friends tonite :-0
