Question about Water Water Heaters
You should bleed off any residual pressure by opening hot water on kitchen / restroom faucets. You can also drain tank down using drain valve on the lower portion of the water heater. Please make sure the electricity or gas is also off depending on what type of water heater you have. You do not want the water heater to start heating with an empty tank.

Turn off the power source before draining just to be safe.

Its A Possibility The Left Over Water In The Hot Is Frozen. If Your Line Is Exposed Outside Somewhere It Can Easily Freeze Up. Turn On The Hot Water Everywhere In The House And If Accessible Check The Lines To See Where The Warmth Ends. You Can Leave One Off Over Night In Hopes That It Will Eventually Defrost.

Many states building codes require a pressure regulator and expansion tank for hot water heater installation. Check the pressure regulator if you have one as this would only affect the hot water pressure. Adjust or replace. Rap the expansion tank like knocking hard on a door. Hollow sound is good. Dull thud means it needs to be replaced as it is filled with water.

Usually when you are having a problem at only one fixture, and not any others it is a sign that you have a faulty fixture. Hope this helps.
