    Troubleshooting hot water cutting off on grohe shower mixer valves
    I have grohe shower faucets and my bath.. I am having problems with the hot water cutting off when I take a shower.. could it be the shower mixer valves or could the temp. be set to high. I turned it down some but it still cuts off after a certain amount of time. I need some suggestions on what I should do to fix the problem. Please help as soon as you can.. I would like to take a hot shower for more than 2 minutes.. thank you and I would appreciate any and all help. Also, when I turn it on it stays hot for about 10 minutes then goes cold for a while and then gets hot again. HELP!!

    It sounds like your Temperature & Pressure Control valve is malfunctioning. Best way to deal with it is to replace entire cartridge. By replacing cartridge, you replace every part that may be responsible for fluctuation of hot water delivery.
