Grohe Thermostatic shower valve trim 19 229 with knob handle. Can't remove the knob to get at the rough-in valve.
Can't for the life of me figure out how to take off the knob... no set screw, no notch. the instructions say to turn it to the 100 degree point and then remove the cab. How to remove??

Anyone??
I can't even see a seam... does the 'cap' consist of the knubbed grip ring? Or is the cap only the part in front of the grip ring? I can't even see a seam... does the 'cap' consist of the knubbed grip ring? Or is the cap only the part in front of the grip ring?

The thermostatic stop is set too low.
Havent set a grohe before but most other thermostatic shower valves work similar.
pull off the handle(however a grohe handle comes off . . ) there should be a notched ring or stop which keeps the handle from going all the way hot. pull out the ring and turn it a few teeth hotter put back and reinstall handle try water temp and adjust again if necessary.
Do you mean the other faucets in the house are hot and only the shower is warm?
If so there is an anti-scald adjustment on the faucet that needs to be turned up a few notches. Havent adjusted a Grohe faucet but most faucets you rmove the handle and behind the handle is a nothced adjustment ring that prevents the faucet from getting too hot. This ring, or stop, is pulled out and twisted clockwise(or counter clockwise to set higher or lower max temp, then pushed back.
maybe you can look up grohe to see which way ring or stop adjusts for hotter water.
the temp, control valve is getting to hot!!! there for only let so much hot water go thru, did you take the inner parts out when soldering this in, if not you might have damaged it, and if so need to replace the cartdrige
