I have a Grohe 34-122 shower mixing valve. I have cleaned the check valves and shower heads. The hot water pressure is good in the rest of the house (including the same bathroom sink) and the cold water pressure in the shower is great. The hot water in the shower is a dribble. I have cold water flushed the hot water pipes for 2 hrs, no help. My next thought was to replace the check valve on the mixing valve. Is this a possible source of the problem? I have had sediment in the lines, but have a filter system now. I am thinking if it is not in the valve it must be the pipes near the shower.
Should I replace the cartridge too? If these things fail, is there anyway to unclog pipes without ripping out tile and walls?
Thanks
