Yes use pipe thread seal. The center is turned to open and close no need to remove plug. If is frozen replace.

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.

they have this common problem ck out here.. https://www.youtube.com/watch?v=s5eWvRzEmuQ hope this helps.

Have you turned the knob on compressor regulator clockwise.?

indicates a failing start/run capacitor for the motor as most small compressor do not have an un-loader for the start and the motor is strong enough to start with a reduced load when the controller switches the power back on

the reed valves/ poppet valves have failed in the cylinder head /s allowing the air to continually pass from in and out with each stroke

What you need is something called a volt-ohm meter. Obtain one and use it to test your switch and wiring.

Check for internal leaks ... Some time it is simple O0ring replacement. Better to replace a fitting completely with more advance options. Or even better toinstall Digital Controller. Check this site: www.CompressorController.com

Pressure switch problem ! Replace all for Digital Controller. Check this site for solution: www.CompressorController.com

Do you meant - your air pressure switch ? Advise - install an digital Controller and all problems with your compressor goes away. Check for Compressor Controller

This compressor has a bleed valve under the tank. It is used to drain pressure. It may be cracked open.

Could be the belt is off or the pistons are not reciprocating

first you have a reciprocating pump and the hissing you ear probably comes from the unloading valve on the pressure switch(it will look like a bike tire valve)if there is air coming out the valve when the compressor is off it probably means you have a bad check valve.This valve is use to unload the pressure inside the pump for an easy start .a motor always drive more amps on start up if you cant unload this pressure you will trip the overload(you probably have a reset button on your motor)check the specs on your pressure relief valve ,its a small pump maybe its just adjusted to high.in this case your pressure relief valve will open .If the pressure is fine and there is air coming out the relief valve then you have to replace it!to adjust your pressure turn the screw on your pressure switch clockwise to increase and counterclockwise to decrease .usually you have a 30 psi between cut-in and cut-off called the pressure differential.It can be adjusted on some pressure switch.be sure you put some teflon tape on the treads if you replace something to avoid air leaks.hopes this help!

There is a valve on the unit that is connected to the motor, this valve is adjustable. Look for the cover housing where the cord goes into a box that is mounted on the tank.. Some models have a lever that turns the unit on and off there. Take the cover off and see if any parts are loose. If not then there should be a screw that you can adjust.
