Using a wrench with a longer handle; or a breaker bar, can often help loosen stuck valves. Just be careful, you may be able to exert enough force to actually snap the valve.
Opening the valve on occasion will help ensure that it is working properly. Opening it will also help release any excess pressure that is built up inside the tank. This exercise could help you detect any leaks that your unit might have.
When you see water coming out from the water heater release valve, there are two most likely causes. The relief valve is working the way it`s intended, and water drained to reduce the pressure inside the tank. There`s a problem with the valve, such as a faulty seal, and the water is unintentionally leaking.
For most units, open the water pressure relief valve by simply lifting the valve up until the attached brass stem rises. When you do this, hot water will rush out of the pipe near the bottom of the water tank. Then, push the lever back down to close the valve and stop the water flow.
The most common cause of high pressure in a hot water heater is the excessive buildup of steam or air within the tank. This can happen when the heat exchanger inside the tank becomes blocked with sediment or mineral deposits, preventing the heated water from properly releasing steam or air.
It`s important to remember to close the pressure relief valve on the hot water heater when you are through draining it. Otherwise, water will run out the valve and through the discharge pipe once it refills.
The T&P valve, or temperature and pressure relief valve, is one of the most important safety devices in your home. If the temperature rises above 210 degrees Fahrenheit or the pressure exceeds 150 psi, the valve will open and relieve the pressure inside the tank.
If a relief valve becomes clogged and won`t open when it should, the result could be a very serious explosion called a BLEVE EXPLOSION.
A pressure relief valve that is stuck open can allow too much oil to bleed off. This results in a lack of oil pressure and catastrophic engine damage. A valve stuck closed will result in excessive oil pressure. This can blow out the oil galley plugs in the engine block.

ANSWER : The small black valve is called a thermal relief valve. If it is open you will have no pressure. If the water is getting hot enough to pop that valve, there might be internal problems with the pump.

The thermal relief is spraying water, do I need a new pump or is repair possible?
ANSWER : First just try replacing the relief valve. This valve will do this if the pump overheated from being in bypass (trigger closed) to long, if it freezes or if there is a sudden large increase in pressure. If the valve did its job it will have prevented damage to the pump and replacing it is all that will be necessary to get you up and running again. If you replace it and you find you have low pressure then you will need to rebuild the pump or replace the unloader valve. If you have any questions please feel free to contact me using the information below.Sincerely,Aron KerrLanda Northwest, [email protected]

Brand new machine and it ran fine for the first 5 minutes then when I squeeze the trigger now the pump takes a second to click on then when it does the engine stalls
ANSWER : Sound like you need to replace the unloader valve,or take it apart and free it up,lube the seats and o rings and retry the washer to see if it works.The valve has the pressure regulator in it so the knob that you adjust the pressure with needs to come off and then just unscrew the unloader valve.
