I just saw the video. I started plumbing full time in April 1972 and I would change them all to just about anything. They look like total junk. I have not seen one in use but I am sure I don't need to. Hope I didn't sugar coat it to much

Did you by any chance read the posts before yours that explained that the problem is not the valves?

The problem is in the expansion tank above the water heater. I, and others who have posted, had the same problem and replacing the expansion tank fixed the problem.

There has been no further "valve problem."

If the valves work there is no sense in replacing them.

For those of you still looking to replace and upgrade your push/pull shutoffs, Sharkbite makes a push fit ball valve that will work with the CPVC piping found in our homes. These fitting are found at most Home Depots and fairly simple to install, link below will bring you to the website (hopefully)

TKS!! that is an interesting and appears to be a well made push on valve / fitting, that is easily removable as well and the price is about the same as a standard glue on valve. It would also solve the issue of needing to wait a min of 30 mins for cpvc glue to set before it can be pressure tested.

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.
