Wilkins 720A problem????
I installed a wilkins 720A PVB. I pressurized per the instructions. When I had the inlet side open, everything seemed to be fine. When I openned the oulet side, water starting coming out from under the cap. If I closed the outet it stopped. What I did notice was if I left the outlet side open partially, no problems. Not sure if this is correct or I have a problem.
