All water heaters have a drain plug at the bottom. It is there so you can perform routine maintenance and protecting its warranty by draining the bottom of the tank and flush out the sediment to prevent the build up and stop any rusting of the tank from the inside out. You may have a little sediment in the shut off and try to give it a small twist to tighten it a little more. If this doesn't work try a Hardware store and they sell caps designed to stop water from flowing in garden hoses or sprinklers. Its the cap on sprinkler you remove to add another sprinkler hos to when watering They are either plastic or metal.

Heater Drain Valve
2016-12-14 13:34:12 · answer #2 · answered by Anonymous · 0⤊ 0⤋
As the name states, it is for draining the tank. This is most commonly used when draing and flushing the tank to prevent mineral deposits from settling on the bottom of the tank. This is more important on gas heaters since the heating is from the bottom and the heat has to go through the deposits to heat the water. The valve may have something stuck in it. You could hook up a garden hose to an area to drain it, and then open and close the valve a few times to clear it. If that doesn't help, you may want to drain the tank and replace the valve.

The purpose of the valve is to allow draining of the tank for repairs as well as flushing the sediment out of the tank. The leak could be caused by sediment stuck in it . Your best bet would be to drain and flush the heater and replace the leaking valve. For a step by step guide, check out the water heater page at www.hvac-for-beginners.com

Is it the drain valve or the pressure relief valve? The drain valve will be located at the bottom of the tank, the Pressure relief valve is at the top, but has a pipe that runs down close to the floor. If it is the Drain valve, just have it replaced, if it is the pressure relief valve, then to much pressure is building up in the tank and it could blow up. If the pressure relief valve is the culprit, call a plumber NOW. And stay away from the tank.

oddly enough, too drain it.
usually for maintence. some manufactures recomend you drain some water from the heater every so often to remove the sediment that collects on the bottom of the tank. This is suppose to extend the life of the unit.
Depending of the age of the unit the valve could be repaired or replaced.

This feature is installed so you can regularly (every 30 to 45 days ) drain your water heater , thus preventing mineral buildup creating a less efficient heat and causing an irritating racket due to mineral buildup. The other reason is when replacing a W/H you can drain it , making removal a ton easier

IF the leak is comming from around the drain valve it must be repaired! The drain valve is a "PRESSURE RELIEIF VALVE" If at any time the water heater heats up the water to hot and the water heater builds preassure if there is no relief valve to releive the preassure.... A very bad explosion....

This drain is there to drain the sediments out of the tank. After you drain the sediment out, you can tighten the plug with a channel lock to make sure it is on all the way!! Good Luck and Happy Thanksgiving!!!
