Drain valve in Porter Cable air compressor

Drain valve would not allow pressure to build in tank. I continued to tighten and it came out. After re-screwing in, pressure will not build at all, air is escaping.

Do I get a new valve?

This valve works backwards, you screw it out to stop airflow. If that doesn't work, replace the valve.

I have a porter cable compressor, but the pump won't shut off, and the pressure won't build it


Hi

Here are a few things to check, you may have already checked some of these.

*Electricity...Compressors will run best with full 115Vot 15AMP/Or 220V electrical supply from a circuit, over the shortest electrical cord as possible.

*Air Leaks..Place your ear close to the compressor and listen for air leaking, if you hear air that is not normal and means you have to locate and repair whatever it is that is leaking.
*Check the air unloader valve... The air unloader valve will blown out air when you turned off the compressor, that is normal.
But it should not have air leaking out of it all of the time. If so then it is faulty and in need of repair/replacement.
*Valves...If either the intake or exaust valves fail, breaks, or fails to seat, then your compressor will run 24 hours a day and never build up to the correct pressure for shut-off.
*Gaskets...Check to see if your gaskets have failed.
You could have a gasket failure between the pistons and you will never know it because it shows no external air leak.
If this situation happens then the air will only cycle between cylinders and never build up the correct air pressure.
One way to check the gasket is remove the air filter, then put your hand over the intake.
If correct then it will **** you hand against the intake.
If the valve or valves have failed then you will feel the air sucking in and blowing out.
*Piston Rings and Cylinder...The piston rings could be stuck,broken, or worn and not allowing the correct pressure to build up in your tank.
A worn cylinder will also contribute to the problem of pressure build-up.
*Pressure Switch...Check for air leaks at the pressure switch, it has a rubber diaphram that can fail and leak air out of the system.

Hi,
Check to see if the switch will kick in if the pressure is released from the hose going to activate it...if so then the problem is the air being trapped between a check valve and the switch in the hose...
I think that is your problem...
There should be a way for the air pressure to change and represent the tank air pressure accurately....
The different compressors all have different ways of checking the air and then allowing it to release as the the tank pressure decreases..

There is a small hole there somewhere that is clogged with dirt and or oil...find that and clean it and you are in business again...

The machine came with this valve with screw showing (i.e gives the impression of it being open). When I left it this way, my machine filled correctly. When I tightened it, the tank gauge did not fill up, and there was air coming out from that valve.

I have a porter cale C5101 compressor. It hesitate to auto start when the pressure is low, always trip my circuit breaker.


What amp breaker do you have this hooked to. I would use no less than 15 amp ,preferrably a 20 amp. Next do you drain tank after use on a regular basis. If you don't moisture can build up inside tank and cause hard starting on automatic. If you need to drain tank there should be a drain valve on bottom of tank. try turning it counterclocwise with compressor off. If it dosen't turn that way try clockwise,air and moisture should drain. If you have alot of water in tank then shut valve and turn compressor on and bring to full pressure,then repeat draining procedure until no more water comes out. Hope this helps. Thank you

Air Leak From Pump Head on Porter Cable C2001 Pancake Compressor


The real question is where exactly is the leak coming from. Compressors have a pressure release valve designed to let the pressure off of the compressor motor so it can start when there is pressure in the tank. This valve is often the culprit and fairly easy to replace. You can order it direct from porter-cable online. Just in case double check the drain petcock sometimes these get worn and won't close completely and can easily be over looked when trouble shooting.

Porter cable model 2005 type 3 wont build pressure


The check valve is most likely the problem,or the compressor is bad.The check valve actually holds the air in the tank,without allowing the air to retreat backwards into the compressor.
