So you want to stop your water heater from leaking, there are several causes of water heater leaking ranging from loose valves to corroded thermostats.stop-water-heater-leaking

However, water pooling around your heater does not always signal a leak.

Depending on the location of your water heater, season, and if the water disappears, you may be experiencing condensation. The condensation forms when the cold water fills the tank and then drips down. If the problem appears when the tank is first but then disappears when the water in the tank has had a chance to warm up, this usually indicates condensation.

If the water pooling does not dry up, check out the following troubleshooting tips:

  • Tank

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 and you’ll probably need to contact a qualified water heater repair person.
  • Vent

On gas water heaters, check for obstructions in the vent. If you find any, shut off the water heater and clean out the flue. If the problem persists, call a plumber.
  • Temperature-pressure relief valve

Water may be coming from the temperature- pressure relief valve, which releases water when it senses excess pressure. Excess pressure can be caused by the temperature being set too high, by the main water supply pressure to your house being too strong, or by special valves that reduce water pressure in your water supply system not allowing for hot water expansion in the tank.
  • Heating element gasket

On electric water heaters, leaks can spring from heating element gaskets. Turn off the electrical power, shut down your water supply, and drain all the water out of the heater before replacing the gasket. Also, before turning the power back on, be sure to turn on the water supply to the heater and run hot water into a sink in your house to release air from the water heater tank. Do not forget this step as failure to do so could destroy will dry fire the heating element. The element must be surround by water before you restore power to the unit.
  • Drain valve

If water leaks out of the fitting at the bottom of unit, simply tightening the drain valve. If the valve itself is defective, you will need to replace it.
  • Water pipes

Inspect the water pipes connected to your water heater. If you water-heater-leaking-repair-personfind the leak is coming from your pipes, tighten the fitting where water is escaping. If tightening does not work, you will have to replace the fitting. It is possible that this piping is copper and you should call a plumber.
