Water Heater Leaks |
If water pools around the base of your water heater or you hear the sound of water sizzling on the burner, it doesn’t necessarily mean that the tank or plumbing is leaking. In many cases, condensation forms when cold water fills the tank and then drips down.
If the problem appears when the tank is first filled or during chilly seasons when incoming water is particularly cold but then disappears when the water has had a chance to warm up, this usually indicates condensation. Another possibility is that the water may be coming from the temperature-pressure (TP) relief valve, a condition that demands the immediate attention of a plumber or appliance repairperson. 1) Look for signs of a leak along pipes, at valves, and around the tank area. If you discover a leak, repair the problem yourself or call a plumber. If the tank itself has a leak, have your water heater replaced.
A water leak may be cured simply by tightening the drain valve or by closing a TP relief valve that’s open. But if the leak is serious, be aware that water heaters have limited life spans; it’s possible that your tank has become corroded. If that’s the case, the water heater must be replaced.
2) Look for drips at the TP relief valve, which releases water if it senses excess pressure. Excess pressure can be caused by the temperature being set too high or by special valves that reduce water pressure in your water supply system not allowing for hot water expansion in the tank. If this appears to be the case, consult your owner's manual for the proper procedure to follow.
3) If there is no water dripping from the TP valve, minimize hot water use for a couple of hours and then check the water heater again. If the leaking has stopped, the problem is probably condensation. Check for obstructions in the vent (gas water heaters only). If you find any, shut off the water heater and clean out the flue. If the problem persists, call a plumber.
