My kitchen and bathroom have no cold water coming out of the faucets or the bath tub, but the hot water side is flowing good. My second bathroom has cold running water out of the faucet and bath tub. Ive checked all the water lines and there are no leaks or no lines busted. What could be the problem?

Has any work ben done recntly?

Possibly a frozen pipe?

If someone has recently done work on your water lines it is possible that a line was shut off and forgot to turn back on.
