What To Do If My Water Heater Leaks From Overflow Pipe?

When you buy a water heater, you will expect it to be efficient all the time. Unfortunately, those expectations are not always met. The best equipment can break down or experience technical issues that are beyond your control. The water heaters can develop problems over time that manifest as an overflow. Thankfully, this is fixable. Read on to learn about what to do when your water heater is leaking from the overflow pipe!

Is A Leaking Pipe An Emergency?

A leaking overflow pipe may not be considered an emergency. At least not for most cases. However, this can become an emergency if your water heater leaks hot water continuously or at a high rate.

Why Is Hot Water Coming Up From The Overflow Pipe?

The overflow pipe is where the water passes through when the valve is open. A leaking means that the water heater is working above the set pressure and temperature. This requires immediate attention.

How Do You Fix It?

So, how do you go about fixing it? The steps include the following:

  • Turn off the gas or power
  • The area that is located below the water heater should not be filled with water if the overflow is not a serious one. If water is found, the water heater probably doesn’t have water, then you have to shut off the electrical and gas supply immediately.

  • Inspect the heater for leaks
  • Watch out for leaks in the heater. If you find that there is a leak and the heater is off, flip the T&P valve to let the pressure out. However, you need to flip it slowly. Most are prone to damage if you flip it too fast. A leak means you may need to re-thread the valve with plumber or Teflon tape.

  • Remove debris from the valve
  • Dirt usually clogs the main seal. See if there is any debris blocking the seal by opening and closing the valve. Water should come out from the overflow pipe and flushing should the dirt around the seal.

  • Release the pressure from the system
  • Open the hot water faucet to reduce the pressure. If the cold water inlet is not open, this is a temporary flow. Then, open the overflow at the bottom of the heater. Place and connect a garden hose that brings the water away from the house to the drainage. Let the overflow stay open for a minute.

  • Replace the overflow pipe
  • You may have to cut off the overflow pipe depending on how it was put in. After you remove the overflow pipe, take out the old valve and install a new one that is free of sediment. Reattach the overflow pipe and be sure to wrap the tape along the thread.

  • Confirm the fittings
  • Do a last check on the tightness of your valves. Reopen the inlet and check the overflow pipe. If you find any leakage, call a plumber.

    • Power on the heater

    Resume normal heater operations by powering on the heater.
