Replacing Temperature and Pressure Relief Valve in Water Heating
As said before, Temperature and Pressure Relief Valve is the safety element that must work properly anytime, while rated equal or higher than the working pressure (found on the rating plate), protected from freezing and without any obstructions, including the discharge pipe. How it works As said, TPR valve is factory installed on all water tank heaters, designed for pressures up to the maximum of 150 PSI in residential applications

Depending on the cause of the problem, it may be possible to correct this at the regulator, but don't try boosting pressure at a gas regulator unless the pressure has always been too low
The water heater relief valve why does it leak.
Have it looked at by a local plumber call The third reason a water heater relief valve leaks is water pressure, the relief valve is set to relieve pressure at 150 PSI (pounds per square inch) if the water pressure in your home rises to 150 PSI the relief valve is going to leak. Note: Under no circumstances should you plug the end of a water heater relief valve, even temporarily, doing so can cause your home to be totally destroyed and can cause death to you and yours Have it fixed by a local plumber call Also see How to troubleshoot an electric water heater
Hot Water Heater Relief Valve - TPR Valve Replacement
Note: When testing the relief valve, make sure no one is in front or around the outlet of the TPR valve discharge line as the water from the tank might be very hot. The discharge pipe should be properly sized to terminate an adequate drain and connected to a drain (6" above the floor drain or drain pan) and with no contacts with electric part

A very small amount of pressure is inserted in the piping system (12 to 14 inches of water column), the system is then monitored to check for pressure drop. The other option was to leave everything in place except removing the cap from the traps so that when the valve leaks, the pressure would not be applied to the appliance
plumbing - What causes a water heaters relief valve to discharge water? - Home Improvement Stack Exchange
Pressure: If there is no allowance within the system to absorb the increase in pressure such as an expansion tank or a thermal expansion valve and all the taps are closed, the relieve valve will open and discharge water until the pressure drops to below the setting of the relief valve. Temperature: If there is an issue with aquastat, the tank may over heat the water resulting in the temperature getting higher then that of the setting of the relief valve
Tighten it with a wrench.5Turn the cold water supply and gas or electricity back on and, for a gas water heater, relight the pilot light or restart it with the electronic igniter if necessary. With this in mind, be ready to shut off the water supply to the water heater and replace the TP valve if this happens when you test it.Note: Be aware that a pressure relief valve is designed so that water will pour out of it if pressure builds up too high in the water heater
Hot Water Heater Pressure Relief Valve - Introduction
How Hard Could It Be? Replacing a hot water heater pressure relief valve is not that hard, it will take less than an hour, including the trip to the supply store
Marc Says: February 18th, 2011 at 9:50 am Thanks again Ben, the leaking has no signs at the threaded connection it is coming only out of the overflow stem pipe. Ben Erickson Says: February 26th, 2011 at 9:46 pm Hi Brad, Turning off the cold intake valve to the water heater not only turns off the water to the hot water heater, but also to all the hot water pipes in the house

Alternatively, turn off the gas water heater by turning the thermostat to "Low," turning off the pilot and turning off the gas line supplying the water heater. Which are you interested in planting?

The Pressure-Relief Function The pressure in your water tank can exceed safe limits for reasons that have nothing to do with temperature, and which also cause the valve to open and release water. A Bad Valve If your valve is dripping or letting out periodic spurts of steam, it may simply be failing, and it usually isn't difficult to visually confirm this
Therefore, a deeper spill pan receptacle with adequate circumference would be advisable over the shallower, tightly-fitting spill pans commonly observed in the field.

Test The Pressure Relief Valve On Your Water Heater - Boston Standard Plumbing dot Com
If your pressure valve normally leaks a little water, or shows signs of leaking when the valve is closed, this could indicate a problem with pressure build-up in your hot water tank. If the valve shows signs of mineralization or cannot be opened for testing or does not close properly after testing, this could indicate that the pressure-relief valve is malfunctioning
When replacing the relief valve use an approved teflon tape or pipe sealant and work neatly and with care so that there will be no leaks at this location. The result cause dangerous, even fatal BLEVE EXPLOSIONS As our photo shows (above left), mineral salts left behind as hot water evaporates from the mouth of a pressure or temperature relief valve can completely clog the spring that is intended to allow the relief valve to open under excess (unsafe) pressure
Water Heater Relief Valve
If a water heater thermostat malfunctions and continues to heat water non stop the tank would eventually explode if it didn't have a relief valve to relieve the pressure.Watch a water heater explosion when the pressure relief valve fails. Why is water slowly leaking out of the relief valve discharge (drain) line? The pressure relief valve itself may be the problem, especially if its an older valve
However, if a leak results immediately after a test, simply operate the test lever several times to free lodged debris that may be preventing the valve from seating properly. The temperature and pressure relief valve (TPR valve) opens to release pressure buildup in the water heater when the temperature or the pressure get dangerously high, preventing a possible explosion
