Low Hot water pressure with new valve
Posted by David on June 13, 2001 at 15:08:56:
I purchased and installed a new moen single handle tub and shower mixing valve part number L82383. I had to cut the pipes back and sweat the new valve to the copper pipes. I got the hole thing in and checked for leaks and water tested it and everything seemed to be OK. I had new tile installed and went went to put on the trim ring and handle and the hot water pressure was very weak. I followed the instructions for removeing and cleaning the cartridge but the problem did not go away.
My question could the solder have gone into the piping system and is cloged the 1/2" copper pipe. The rest of the house pressure is great.
Moen is sending me a new cartridge but Im worried that something with the pipeing behind the brand new tile is causing this problem.
Any advise would be helpful.

Thanks in advance,


IF it is the 1/2" copper pipe that is parchilly blocked can I fix it without ripping the wall apart?
