What Is An Overflow Pipe

A temperature and pressure relief valve does just what its name suggests: relieves temperature and pressure from a water heater. If the internal pressure in your hot water heater reaches or exceeds 150 pounds per square inch, or if the temperature of the water exceeds 210 degrees Fahrenheit, the temperature and pressure relief valve will open.

When it opens, hot water comes rushing out of the water heater and through the temperature and pressure relief valve drain pipe. This release of water prevents the water heater from exploding due to excess pressure and temperature. Given this crucial function, its important that you ensure the proper operation of your temperature and pressure relief valve at all times.

Gas Vs Electric Water Heater Leaking

The type of water heater you have may affect where your leak is coming from.

Electric water heater leaking may come from behind the access panel. Be careful: wet electric water heater components or insulation are an electric shock hazard. Make sure you shut off the electricity at your circuit box before you check for leaks! After youve turned the power off, remove the access panel and safety shield and check for moisture inside. Tighten any loose bolts while youre at it.

Gas Water heaters have a flue the entire length of the heater in the center that vents carbon dioxide from the burner. Look for water leaking on the burner at the bottom of the tank. If you find any, then your flue is the source of the leak. Unfortunately, youll have to replace the entire water heater.

Determine If You Have A Water Heater Leak

After you find the meter, make sure everyone at home stops using water. Shut all taps, toilets, fixtures, and water appliances. Your meter should have stopped moving.

How To Test For A Leaking Pressure Relief Or Safety Relief Valve

If you believe that a safety relief valve is leaking, or if you want to do routine maintenance to avoid valve leakage in the first place, its a good idea to be aware that it is possible to test for a leaking valve using a pressure gauge.When performing a seat tightness or leakage test, the inlet pressure of a pressure relief valve is maintained at a specified percentage of the valves set pressure so that the valve technician may assess the condition of the valve.With the AccuTEST inline valve testing system, you can take advantage of a one-of-a-kind feature called the Lift and Hold test, which is particularly intended to detect leaks.

The system performs an automatic leakage test in accordance with the specifications provided by the operator.The percentage of the specified pressure and the length of the test are determined by the operator.When the operator begins the test, the AccuTEST system takes over, maintaining the valve at the appropriate percentage of the set pressure for the length of the test.While the system is maintaining pressure on the valve, the operator can count the number of bubbles in the valve to assess its condition and determine whether or not the valve is leaking.

An Open Or Worn Drain Valve

Check that the drain valve is closed if your water heater is leaking.

Your water heaters drain valve is at the bottom of the tank. If youve ever scheduled a water heater maintenance visit, youve probably seen the plumber use this drain valve to flush out sediment buildup.

On the other hand, if the connections wont tighten or the water leaks directly from the pipes, its best to contact a plumber for help. They can inspect the pipe connections and repair or replace the leaky pipes.

Another possible place for leaks is the temperature and pressure valve. A leak at the T& P valve is a more serious situation and you will want to take the time to figure out the cause. A T& P valve will not usually begin dripping or leaking unless there is a bigger problem.

If the valve was removed recently, it’s possible it is now failing to seal properly. Tightening the valve, or reinstalling it with fresh plumber’s tape wrapped around the threads, may solve the problem.

If the water heater is heating the water too much, the excessive pressure may be causing the T& P valve to leak. The solution might be to lower the water temperature or to install a water expansion tank if you don’t already have one in your plumbing system.
