I have a problem with the cold water in the bath tub , it all of a sudden stopped running and I when I pullled the cartridge both the hot and cold would not shoot out . When I reinsert the cartridge and turn the knob the hot water comes on immediately but still no cold . The pipes are galvanized and the faucet is moen . Are the pipes rusted or is there
A part inside of the faucet other than the cartridge that could be blocking the cold water .:(

You get water through the valve body with the cartridge out? Is the cartridge brass or plastic?
