I don't know what to check? I have running water when I turn on the hot faucet or turn the arm over to hot, but NO water comes out of the cold faucets or if the arm is turned to the right or the cold side! Any help would be appreciated.

First, I would check if your cold water angles top is open. If positive, then you probably have dirt in the cartridge, in cold water passageways. You will have to close water, remove the cartridge, flush it and reinstall it.

But, it would be very helpful if you tell us what kind/type/brand of faucet you have. Thank you

It just isn't one faucet. I don't have cold water in the entire house. We have a well and that may add to the issue. We have hot water at this time.

You have a cold water feed that's been closed. If cold water never entered your house you wouldn't have hot water. Something's been closed down. Cheers, tom

Heve you had ANY plumbing work done on your house recently ?

We had to call our well man who replaced the box that regulates the pressure coming into the house. Eventually we also had no hot water either... no water of any kind. Thanks for everyone's help. I appreciate it.

I wanted to throw this out there, though I may be wrong.

I live in Arizona, and at my moms house, the sun beats down directly on the side of the house where most of the pipes run, and this causes the pipes to become hot, so when the cold water goes through these pipes, the water heats up.

Could this be a possibility?
