 No cold water to one shower
Author: trudr75 (MI)

We have a ranch style house with two bathrooms. One of the showers is not getting any cold water. I thought at first it might be the cartridge inside the handle, I replaced that and it still didn't work. When I turned the water on I tried only turning the cold water on first (the main valve) and when I turned the faucet on nothing came through but when I turned the hot water valve on it came through fine. So for some reason that faucet is not pulling the cold water through any other reasons or ideas on how to fix this?

Does the valve body contain a separate balancing spool ? Is there individual shut offs on the supply inlets of the valve body ? You could remove the cartridge, turn the hot water off at the heater and turn the cold water on to the house and see what happens ?

If the cartridge is not the problem, then I think it is in the valve. Replaced the valve (just the inside part).

Sometimes debris (lime or Calcium or solder if copper piping) can clog up the opening into the valve. Take the cartridge out and see if you can put a wire bent into an ell shape into the opening to loosen the debris and allow it to be flushed out by having someone turn the water on for an instant to blow it out. Place you hand over the valve opening to prevent making a mess in your home. Good luck.
