I have a single faucet in my shower and all of a sudden I have Hot water but no cold!
There is cold coming out of the sink faucet but not in the shower!
Any idea's?
Thank's Mark:confused: :

Some kind of problem with the cartridge assembly I think. Here, shut the water off and remove the cartridge and clean it... Also, at this time, with a friends help... "pulse" the cold water pipe on and off to see if you have full cold water pressure without the cartridge in place. If necessary... after replacing cleaned cartridge and pulsing water, may need to replace the cartridge.

Also... any chance you have a frozen pipe? Just another thought.
