Air compressor leak

When I turn on my air compressor, there is a leak on the side of the discharge non return valve preventing air to accumulate in the receiver. It appears that the check valve had a pinhole deliberately drilled inot its side, si that common? Should there be a hole on the check valve on the outlet of compressor beore entering the receiver?

If this hole looks factory drilled thats what the valve is for and is weak and needs to be replaced if someone has drilled it into the valve it will still need to be replaced

Can I safely remove the AIRmatic compressor if all four wheels are on the ground?


I suspect that it is not the compressor as it is filling the system
I would be checking for non return valves in the system that is allowing the pumped air back to the compressor and not storing in the air bags or accumulator tank
to answer your question , the car should not sink down as the non-return valves should hold it in place but if you are concerned jack up the car and place it on jack stands so that the weight of the car is not on the air bags

Bostitch 2 hp , 4.5 gal. compressor leaks air out of air cleaner


Air leaking air out of intake when the compressor is not running and pressure in tank indicates bad check valve. Follow the discharge tube to where it connects at the brass valve mounted to tank. This valve is a non-return valve and can be replaced with generic valve. When air blows or pulsates out of intake as the compressor is running is indication that pump has bad valves or blown gasket/ gaskets. Good luck

I have a Dewalt D55141 Air Compressor that will work normally through one or two cycles, and then when it try's to power again it will just hum and quite repeatedly until I shut it off. It also bleeds...


I believe that you have a very simple problem related to the in-tank check valve. Follow the discharge hose from the compressor to the tank. It should connect to a brass or chrome valve. This valve has a one way check valve that allows air into tank and not return to compressor (if air leaks back, compressor will be under load (motor will not overcome) and air will leak from the pressure switch unloader valve). With air in the tank, remove the hose at the check valve and spray soapy water to verify leak, replace part or clean as needed. Good luck

After compressor turns off it leaks air from pressure switch


Sounds like you have a tank check valve leaking. It is located in top of the tank. The copper discharge line from the compressor goes into the check valve. Make sure there is no air pressure in the tank. Then Remove the large copper discharge line. Also remove the small copper line from the side of the check valve. Once the lines are removed you can remove the check valve. Most of the time the check valve needs replacing. Sometimes they have large pieces of trash holding them open.

Sanborn 15 Gal. Air compressor "bleeder-valve" will not shut off when compressor shuts down. I replaced with a entire new unit ( which includes this bleeder valve ) and it does the SAME THING...


Leaking bleeder valve /unloader is caused by faulty check valve. Follow the air discharge hose from the pump head to the brass valve at the tank. The brass valve is the check valve designed to keep pressure in the tank and prevent air from loading the pump when the compressor is trying to start. Remove the discharge air tube at the check valve and test for leak. If leaking replace with generic valve available at www.grainger.com or on ebay. Good holidays

My 1 hp. 12 gal. air compressor is not building air pressure the motor runs the pressure won't go above 20 lb.


It could be that the input air filter is badly clogged. I might more likely be that the Non-return valve on the air tank input is not sealing properly and not allowing the tank to build up pressure. This valve is at the end of the main pipe runs between the compressor and tank. It could also mean (less likely) that the poppet valves inside the compressor cylinder head are not sealing properly. Other faults could be worn rings on the compressor pistons or a bad seal between the compressor cylinder head and block.

To check the Non return valve allow compressor to build up some pressure and then loosen union nut on Non return valve. There should be some air released at first but should stop if valve is ok. If leaking remove valve and check for dirt and clean. If valve still leaks replacement is the only fix.

Turns on but only fills to 10 psi and then does not fill more


There is a one way checkvalve installed on the tank that prevents air from returning to the pump. Follow the discharge hose from the pump to the tank. You will see a brass valve that has a 1/4 inch hose attached that leads to the pressure switch where you will find the unloader valve. Check if the unloader valve is leaking and continues to leak when you turn off the pump. If the valve at the pressure switch is leaking ~ then the check valve at the tank is the source of the leak and needs to be cleaned to replaced. Some low volume compressors will never fill if the tank check valve is bad. Check this first and email me for more information. Good Luck
