SOURCE: grohe trim pressure balance valve

i looked at it and there might be a press in cap with a screw underneath where the grohe label is. there also may be a set screw around the shoulder of the handle where an allen hex wrench fits to losen its clamp on the stem. also.......some handles just snap on and just pull off with some tugging and wiggling them just right.

The problem is that the pressure balance unit is stuck...therefore no hot is not sensing the cold water it will not allow hot water to flow...
The lack of use is actually a bad thing as the rubber and such can adhere to the metal and stick the unit...
You maybe able to free it up, but it probably will never work correctly...
I would just replace the pressure balance unit to be sure that it is working correctly and safely...

The holes around the inside of the bowl may be clogged, try using some CRL and scrubbing the holes with a good stiff brush.

I wouldn't risk it in case you ever need to remove it.
I would drain the system down, take it off again and refit with tape or a sealing compound such as Bossfix.

Need to replace a moen tub-shower valve without tearing down a wall. Can you help? Where can I get the valve?

If you remove the handle and the fasia plate you'll see the valve in the center (make sure to turn off the supply valves first. These are located at 3:00 and 9:00 beside the valve. Then the whole assembly unscrews from the center with a large adjustable wrench or a pair of channelock pliers.

Kohler shower facuet pressure balancing problem?

ever since the pressure balancing regulations came out for shower valves, they have went from simple to very complicated devices. sounds as if some foreign material caused the valve to stop working. that valve is quit difficult to reassemble correctly because there is only one way it works and can be assemmbled many ways that do not work concerning alignment of the ports. if you dissassemble it and check that all the moving parts are functioning in the balancing cartridge you can then look closely at the alignment of the ports on the cartridge that the handle is connected to. understanding how the port align as the handle is turned should assist you in assembling it correctly......hope this helps.

Pressure problem with Kohler shower faucet??

Hi pglaw,

My best guess is the supply valve for the hot side isn't open all the way. This valve is right on the valve and is accessed by taking off the front cover plate. This would still allow the pressure balancing valve to let water through but then you would have a small flow on the hot side.

If this isn't it then then cartridge is bad.

Please rate this response and good Luck,, phil
