Its been snowing for a week now. Not sure if that's the problem. But every other faucet works in the house even on the same floor.. the bathroom on the main floor's faucet works but the toilet is a different story.The heater also runs constantly and it's a scorcher in the house.. I'm very confused. Everythign was workign fine the previous day..

If the plumbing is in the outside wall it is possible it is frozen. Turn off the stop valves under the sink and disconnect the riser pipes at the valve. Crack the valves-do you have water coming out? If not, the pipes are probably frozen. If water comes out, you ether have a plug in the main body of the faucet or the aerator on the end of the faucet is plugged. Troubleshoot first and get back to us.

Did you remove the aerator from the spout and then try it> And what's the complaint on the toilet? Back to you, Tom
