push pull valve solution
I too had problems with push pull valves. I replaced several and was at Ace Hardware in Southern Trace planning on purchasing another replacement valve when the clerk there told me how to test the hot water pressure tank (the clerk indicated that this could be the source of the problem). I tried to use a tire pressure gauge to check the air pressure in the tank. When I did water came out. This indicates that the rubber bladder inside the tank has failed. I replaced the tank (about 6 years ago) and my push pull valve problems went away until about two weeks ago. I again tested the air pressure in the tank and had water coming out so I am off to the hardware store to buy another pressure tank.
