I have a problem that may be related to water hammer, but the "standard" fixes for water hammer have not eliminated the problem. Whenever the hot water valve on my washing machine opens (and *sometimes* other fixtures such as my single handle kitchen sink fixture) I get a gurgling and bubbling reaction in my hot water heater. The gurgling lasts 3-4 seconds. This sound is not the same as the popping sound due to sediment. It sounds like air bubbles inside the tank. The reaction was getting more and more violent recently, so I closed the main water valve to the house, opened all faucets in the house and drained the water heater. I then opened the main valve, closed all faucets starting in the basement, and let the water heater refill. The problem went away while the water in the heater was cold, but after the heater recovered the gurgling returned, although it was somewhat quieter. I installed a water hammer arrestor in the hot water line at the washer but this had no effect. The OA Smith water heater is under 5 years old, but out of warranty because it is a "warranty replacement" unit and the origanal warranty has expired. Anybody have a suggestion as to what to try next? |
