How to Flush a Water Heater
HOW TO 
Tags: Water Heater, Flush Water Heater, Water Heater Maintanence
You water heater should be flushed out at least once per year. This is a relatively simple task which I will explain below.
| 1. | Do not shut off the gas or the water supply to the heater. |
| 2. | Attach a garden hose to the draincock located at the bottom of the heater. The draincock usually looks like a regular hose bib (garden faucet) or a round dial with a threaded hole in the middle. |
| 3. | Extend the garden hose to a place where the water can safely exit the heater (e.g. a drain, a driveway, etc.). |
| 4. | Open the draincock to allow the water to exit the heater. Caution: the water leaving the heater will be hot and under normal household water pressure. Also note that if the draincock is made of plastic and the heater is several years old, it may be difficult to open and may break easily if forced. |
| 5. | After five minutes of flushing, fill a bucket with the still flushing water. |
| 6. | Allow the water in the bucket to stand undisturbed for a minute and see if the water is clear or if any sand-like material settles to the bottom. If the water is clear and no sand-like material is observed, go on to step 7. If the water is discolored and/or sand-like material is observed at the bottom of the bucket, repeat steps 5 and 6 until the flush water is completely clear and free of sediment. |
| 7. | Close the draincock and remove the garden hose. |
| 8. | Now enjoy your work! |
