Draining Water heater
Hello All,
We've just moved in and I would like to drain the water heater. It was installed in 2000, but the owner never drained it. What is the safest way to do this without damaging the heater? Water on or off? Pilot light on or off? Etc, etc... Many thanks for taking the time to respond! Alain |

If you intend to just flush it, leave the water on and no need to turn it off. |

It lets air in, thus letting the water go out with more force, carrying more crud. I would turn the water on and off SEVERAL times to flush as much stuff out as you can. Steve |

Most drain valves are junk, espically the plastic ones, once opened it may NEVER close You can buy a cap that fits with a washer to close the drain when your done. be prepared to replaace the valve, like start early AM of day off not end of day Turn burner off leave pilot on. messing with the T&P valve may cause it to leak. your better off opening valves anywhere above the height of the tank to assist draining by allowing airr to enter |

They lime up, and when they do they can fail in the "will never open" position -- a very bad thing. Or, they could fail in the "won't stop leaking" position, but that's easily fixed by replacing it. |

I'd buy a brass one in advance. You can always return it. They are usually 3/4" pipe thread. I think they should outlaw those plastic valves. Mark |

Draining Water heater
To drain...
Turn off gas to water heater. Turn off water supply to water heater. Open drain at bottom of unit, attach garden hose to route water to drain or outside. Open TPR valve at top of unit, to allow air in. Water will come out now! To flush... Once unit is empty, turn on water supply to unit, allow to flow through and out. To refill... Close drain at bottom of unit. Close TPR at top of unit Turn on water supply to unit. Open a hot water faucet somewhere in your house, like in the kitchen. When water comes out there, the heater is filled. Turn on gas and relight pilot. Then, go around the house and purge each faucet for air and debris. |
