Pressure Balance Shower Valve Hammer


I have a Pegasus pressure balance shower valve has started to act up. I installed it several years ago and it worked fine until it suddenly began to cut-off the hot water and make a hammering noise. As you turn the valve towards full hot, the valve begans to hammer and when you get to full hot it almost completely cuts off the water flow. It makes it very difficult to take a hot (or even warm) shower.

I pulled the spool housing out and cleaned it but nothing changed. I didn't pull the stops out because I didn't know how to readjust them.

Any ideas how to stop the hammering?

Get and install a new spool for that valve.

I replaced the spool and the cartridge and it still hammers when you turn it to hot.

I have the same problem with a pegasus valve making a water hammer noise and I also found out that it was a problem with the spool housing (a small cylinder inside that is rattleing around). I replaced it and not long after, the new one was doing the same thing. IT is a pegasus 9200 serries that was purchased at home Depot. anything that anyone knows would be appreciated.

I have the same exact problem. Considering swapping out the cartridge, but it sounds like the valve assembly itself has repeated manufacturing defects or is just a poor design. Anyone able to find a sustainable solution?

I have a Smart Shower Panel. It makes the hammering sound only when I turn on and shut off the hot water. The sound is from the shower panel. I think it is from the cartridge inside the shower panel.
anyone know what is causing it.
