Why is water dripping from my overflow pipe on hot water heater?

When water is heated, pressure builds up in the tank and is released through the overflow pipe. So water dripping or running from the valve can be a sign of a normal, functioning system. Not all leaking overflow pipes are caused by normal pressure build-up. When a leak occurs, the water pressure inside the system will drop.

This drop in pressure will cause water to flow out of the pipe and into the surrounding area. The water will begin to run out the drain pipe, which is usually located in a basement or crawl space. If the leak is in an area that is not accessible to the general public, you may need to call your local fire department for assistance.
