From want you are describing sounds like the high pressure valves are leaking in the HP Head. there are 2 safeties on this unit . If the safety that's lifting is between the low and high pressure cylinders it's hp valves leaking. If the tank safety is lifting at 50-60 psi It should be replaced. It is a 200 psi safety.

POP OFF VAVLE ON HEAD KEEPS POPPING UP


The over-pressure relief valve may be defective if the valve is opening before the desired tank pressure is reached. If not, then the shut-off pressure adjustment (if there is one) may be set wrong. You'll need to find out from the manufacturer exactly what static tank pressure the compressor is designed to provide and then determine if it is working correctly. If so, then the relief valve might be defective. DO NOT attempt to defeat the relief valve under any circumstances - it can result in compressor damage or a dangerous tank failure.

My compressor is building to much pressure and blowing out the relief valve. what do I check


You didn't give the model of your compressor so, for an electric model: Check your gages while the tanks are filling. If the pressure gets to the rated high pressure level for your model and keeps going until the relief valve pops, the problem is with the pressure switch. It isn't turning the motor off when it's supposed to. If the relief valve pops before getting to the max pressure the tanks are supposed to be at then the spring in the valve is broken or weakened to where it pops too early. Replace the relief valve.

Leaking pump protector valve in a Landa SEA series pressure washer


"Protector Valve" could mean several different things. There is "pop-off" safety pressure relief valve and there is a "Thermal Relief Valve". Your pump could be protected with both, or only one of these. A pic would nail it down quickly.

Pressure releif valve leaking


Hot water pressure relief valves serve two functions. The first is to remove high-pressure water from the hot water tank. The second function is to act as a high temperature valve to remove water that exceeds a predetermined point for the valve. Both of these relief settings are preset at the valve factory. Many pressure relief valves will come with a metal tag that identifies these release points. If you're attempting to remove the hot water heater pressure relief valve, pay careful attention to ensure that you replace with the correct valve.

Your hot water heater has a pressure relief valve safety mechanism. When pressure inside the water tank exceeds certain limitations, the valve opens up to allow the pressure to be released. A faulty pressure relief valve will not release excess pressure, which could cause extensive damage to your home. You should test the hot water heater pressure relief valve once every six months to ensure proper operation. If the pressure relief valve fails the test, replace the valve with a new one immediately

Locate the pressure relief valve on your hot water heater. The pressure relief valve has a lever handle on top with a drain pipe attached to it. The pressure relief valve is most often on the side of the water tank toward the top. Newer models of hot water heaters have the pressure relief valve on top of the water tank.

  • Inspect the area around the pressure relief valve for signs of leaking water. If there is leaking water near the relief valve connection, replace the relief valve. If no leaking is evident, proceed with testing the pressure valve.

  • 3

    Examine the area below the pressure relief valve drain pipe. Most water heater closets either have a drain in the floor below the pipe or the pipe is inserted into another pipe to direct the water out of the home. If the end of your drain pipe is not in another pipe or there is no drain in the floor, place a bucket under the drain pipe to catch water when you test the pressure relief valve.

  • 4

    Pull the lever handle on the top of the pressure relief valve up with your fingers. A working lever will lift up without difficulty.You should begin to hear water going through the drain pipe. Slowly release the lever to shut off the pressure relief valve. The pressure relief valve is good. If you did not hear water running through the drain pipe, lower the lever on the pressure relief valve and replace the valve. If the lever is difficult to raise, do not force the lever. Replace the pressure relief valve.


  • Now with all that said if you have a closed loop water supply system and you have a pressure vessal/expantion tank it may have gone bad and is making the TP valve leak. you can call your water provider to see if you have closed loop system.

    Pop off valve on gas water heater making racket. Can just the pop off valve be replaced?


    Yes it can be replaced. This is a temperature/pressure relief valve and is the second most important safety device on your heater. They rarely make racket. Is it leaking? if so yes replace it. Water heaters should have a portion of water drained annually along with operating the relief valve. IF you raise the handle a few times, and it continues to leak, then it should be replaced. If you replace it be sure to replace it with EXACTLY the same temperature and pressure rating that is on it now. Allow the water heater to cool, and drain pressure before removing. If it is rumbling inside, you might have calcium deposits bouncing around in the bottom. Drain some water and see how it looks. (Often if you operate drain, and haven't in a long time it won't reseal)

    Once compressor reaches 125 lbs. pressure, the relief valve opens and releases pressure. the motor then tries to engage but cannot come to full speed because of back pressure I am trying to find and...


    Generally, the safety/relief is set to 140 to 160psi. The pressure setting is stamped on the side of the valve. Replace the valve if it will not hold stamped pressure(cost about $6 at Lowes Lumber).The pressure switch is usually set at the factory to 120 - 130 psi. The unloader part of the pressure switch will not release backpressure unless it reaches set cut-off. The 1/4 inch line attached to the pressure switch connects to air discharge tube at the intank checkvalve (brass valve). The safety valve should very rarely release pressure, only when pressure switch malfunctions and allows pressure to reach up to 160psi. The tank will hold over 300psi so dont worry about the 160psi safety. I am not sure about your exact model number or brand, however most small compressors work the same and share similar parts. For manuals to other similar compessors to to www.dewalt.com. Here you will find manuals to dewalt and porter cable compressors. I prefer to use generic replacement parts from www.grainger.com or from Lowes Lumber. These parts will cost less than factory replacement. If you need to replace the pressure switch, use SquareD brand from grainger. Watch fitting sizes and pressure range. Good Luck on your repair.

    Gravity feed boiler/ american standard model#g27dpgc


    your make up water pressure is greater than the safety relief pressure. The safety should be 30psi lift. the makup usually goes through a regulator called an automatic makeup valve. these valves operate infrequently on a closed system and get rusty. They stick. If yours is stuck open, then your makeup water pressure which is probably greater than 30psi is overpressuring your boiler.
