Question about Porter Cable Cable 135 PSI, 60 Gal. Oil - Lube Stationary Compressor C7510

1 Answer

Drain valve on air compressor won't open or close

I have a model CPLC7060V 60 gallon 135 psi Porter-Cable air compressor.  The valve that drains water from the bottom of the tank will not screw open or close. I'm concerned about putting a tool on it and trying to really crank it open to drain the tank. Tried Liquid Wrench to no avail. The valve is very difficult to reach under the tank, so I haven't been religious about draining it. The tank is about four or five years old, and isn't used real often. If I have to replace the entire valve, could someone please give me instructions on how to do it, or how to attempt to get the valve open?  Thank you.

I would use an ajustable wrenck to try and open the valve. Being at the bottom and in the water, this is a common occurrence. to replace the valve, there is a Hex nut outer fitting (part of the valve) that you have to remove right by the valve "T" handle. Put a wrench on this and remove the complete valve. It too will be very hard to remove. When you install the new valve, use some anti-seize compound to make future removal easier.

How to drain frozen air compressor 60 gallon tank

More than likely it's going to take some heat before you can drain it out.

It MAY only require the use of a small propane torch. BUT if there are any plastic parts on the drain, I would definitely avoid doing it that way.

You could possibly use an electric space heater aimed toward the valve.

Any way you thaw this out remember that as the air/fluid starts coming out the rush of air may freeze it back closed. It may take a few rounds of heat and drain to get it all out.

Hope this helps.

If the motor doesn't shut off at the desired pressure then your pressure switch is either set too high or is broken/stuck. The pressure leak at 150 psi is the safety valve doing its job opening when the pressure gets to an unsafe level in the tank.

I have a porter cable 6 gallon compressor. The motor used to cut out at 150 psi, but now it cuts out at 135. Is this a faulty tank pressure gauge misreading the pressure or a motor cutting out too early

it could be your air pressure adjustment knob, where your air line hooks up, which controls the psi to a lower or highist seting to adjust for different tools and uses.

Air compressor goes only to 100 psi and keeps running should go to 150 and shut off

This is usually indicative of an air leak. From easiest to hardest to fix, it could be:
- a tank drain valve not completely closed or rusted open
- an air line or other part attached to the tank leaking or the joints where it connects aren't tight
- a broken pressure guage
- the piston rings are damaged and/or the cylinder is damaged

Order to put compressor valves back

If you go to and search on your model number, they have a rough diagram of your valve plates that should get you close to where you need to be. I usually look at them from the mechanical perspective; make sure one reed valve is on the valve plate side away from the intake chamber of the head (the side the air filter is attached to) and the other one is towards the output side. You can usually figure out where gaskets go by how they're formed.

Compressor keeps blowing release valve

Compressor pressure switch not working properly. Remove cover over pressure switch. Drain air out of tank. pressure switch contacts should open. If contacts do not open they may be stuck or welded close. Remove power and gently pry contacts apart. If they where welded together this will correct. If this doesn't correct replace pressure switch

Should air compressor tanks be drained daily and if so why should they not be left under pressure from day to day? Will the air under pressure in the tank cause additional water vapor to accumulate?

No additional moisture will accumulate over time. Some existing moisture may condense as the unit cools down, though. If you drain off the water at the end of the day, I see no good reason to completely drain the air.
