I recently changed the faucet in my kitchen and the next morning the plastic shut off valves under the sink had popped out. I pushed them back in and it was fine for a couple of days and they popped out again. The toilet downstairs has also popped out and the sinks upstairs have popped out. We called a plumber and he said the shut off valves had to be replaced. I can't believe they all are failing at the same time after we changed the faucet. Yesterday afternoon the ones under the kitchen sink popped out and would not go back in to turn the water on until I went upstairs and pushed the one under the master bathroom sink then I could push the ones under the sink back in. The plumber checked the pressure and it is 80 psi. I'm at my wits end and don't know what is going on. Any suggestions would be appreciated. At this point I am thinking we need to call another plumber.
Shut off valves keep popping out

Post a picture of the valves. If you are pushing them on, chances are they are a garbage, junk, piece of crap valve. You should be replacing with something compressed or soldered

I am pretty sure that I know exactly what kind of valve the poster has, and the plumber is right, the valves need to be replaced. The valves are garbage.
Well fill us in man, what the hell is he talking about?

They are a supply valve that uses an Oring seal and stainless teeth, much like a Sharkbyte fitting. After awhile, the little raised plastic shoulder inside that holds the valve in the on position can get worn down, and they can shut themselves off when water is flowing through them.
The manufacturer is Accor.
An apartment company I used to work for used them almost exclusively for awhile. They had a couple of them blow off, and the resulting flood claims convinced them to stop using them. I still see them in new home construction quite regularly.

Also- I would think 80PSI is a little high and maybe causing the valve handles to pop. Pressure possibly not measured during a thermal heating event or supply pressure surges.
Have not checked but a$$-u-me there is a water pressure warning in the install instructions.
