Or maybe someone has played with the Regulator and adjusted it to this????

Try readjusting the regulator first and if that doesn't work, get a new regulator.

Sounds like the regulator is faulty, normal running air should reach 110 psi, this will allow you to run tools...

First take off the head on the air pump and check the reed valves on the valve plate. If they got hot and warped or cracked they'll work to a point then no more pressure can be built up. Next check the pistion ring and cylinder wall. If either is damaged you'll only get so much pressure build-up then it will leak past the piston.

My compressor will not go over 20 psi i have a craftsman 921 4 gal 125 psi compressor and it will not build past 20 psi i do not know how to get to the pistons and stuff what do i do?


The problem with compressors not building pressure is usually a bad pressure switch or bad regulator. Does the motor shut off at 20psi or does it continue running and not build pressure? If the motor continues to run with no increase in pressure, the you should go over the machine looking for air leaks from your regulator back all the way to the motor. Any air leak while the compressor is running can cause the pressure to "peak" way before the intended shutoff that it is regulated to.

The compresor is not building up the pressure, it only reaches like 15 PSI .. and is not the drain valve


check the regulator valve. the black cap must be pulled out slightly to allow it to turn. adjust that while watching gauge for change. there is also another pressure release near the pump be sure it is seated fully.

Pressure in the tank only builds to 30 psi


Bad check valve. But I would check the regulator, by turning it down to about 10 PSI and running it and see if it builds again, if that works then it is the check valve. But from what you are saying I would replace the check valve anyways.

Compressor runs for a bit and builds about 30 psi


Remove the belt and try and turn the pump by hand if it turns free then you have a bad motor and it will need to be replaced

Craftsman 30 Gal. 150 PSI Not building air over 45lbs


The compressor valve may have a faulty gasket or seal, and maybe leaking air internally. Or the compressor might be going downhill. You can try to replace the valve seal and see if that makes a difference, otherwise you need to replace the compressor.
