I use paper towels stratigicly placed to find the actual leak. It may be a bad solder joint, or it may be a bad PVC joint, depending of the actual source. You may need to "start" over, with new materials and connection methods.

The air is coming out of the pressure switch but the problem is the tank check valve. The tank check valve is on the tank where the large line from the pump feeds into the tank. There is also a smaller line, either plastic or copper, from the check valve to the pressure switch. When the pump shuts off the check valve is supposed to close and the pressure switch opens a valve that lets the head pressure bleed off through the small line. This lets the motor start the next time without any pressure in the head. If the check valve isn't closing properly the air will leak out as you describe.

25 gallon up right speedway series aircompressor leaks air out at pressure switch

This is usually indicative of a broken tank check valve. It's a valve on the pressure line from the pump to the tank. It let's air into the tank then closes so the pressure switch can bleed the air out of the pressure line and head through a plastic or copper line so the motor can restart when the pressure drops. Rarely you can remove the valve and clean the seat and valve but more often than not it has to be replaced.

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.

T30 model 2475N7.5 Ingersoll Rand will not bleed off head pressure when up to 145psi shuts down but will not start when at 95psi takes out breaker 50amp

If air continously comes from the bottom of the pressure switch (bleeder valve) you have a bad tank check valve. The check valve is located on the receiver tank where the copper line from the compressor head goes to the tank. The brass hex between the copper line and the receiver tank is the check valve. Remove it after making sure all pressure has been bleed off the tank. Then you can inspect it. I recommend replacing it unless there is something obviously stuck in it that can be removed with no damage to the check valve. Another way to see if it is the check vale is to loosen the nut on the copper line at the HP head that goes to the receiver tank. If air continously blows from the copper line the check valve is leaking.

The pinhole leak is most likely your problem. However pressure switch leaks are often misdiagnosed.

Drain all the air from your tank.

Follow the 1/4" copper or plastic line that connects to the pressure switch back to where it meets a fitting that screws into the tank.

Take the lines off of that fitting and take the fitting out of the tank. That is your check valve. Be sure that isn't leaking or obstructed in anyway.

If it isn't leaking or obstructed I think you need to replace your pressure switch. Without having hands on access to your unit I can't be sure.

Leaking air

When the Pressure switch shuts off, the little air valve in the pressure switch vents the copper line from the compressor, to blead the pressure from the compressor so it's easier to start the next time. If it continues to leak, the check valve between compressor and tank must not be holding.

Difficult starting, seems compressor unit has excessive resistance, you can smell the burning, oil level is full

A couple of things to check is to see if the unloader valve is working, there is a copper line that goes to the pressure switch that dumps the air pressure off the pump to allow a start under no load. with the compressor off and the tank up to pressure loosen the fitting on the small copper line to see if there is any pressure there. if there is either the valve is plugged or the small lever under it from the pressure switch is not hitting the valve to unload it. The other suspect is that the start capacitor in the motor is bad. I assume that this is a 220 volt single phase motor. you would best take the motor to a motor shop and have it tested. this is something that I would advise you have a professional do if you are not experienced with motor repair.

Compressor stops then leaks down to low setting

That little copper line is an unloading line, to bleed compressed air out of the compressor head so that the motor can more easily start the compressor. Pressor switch should be threadded into top of air tank, and the unloading valve is built into the side of the switch. When the tank reaches the high pressure setting the switch disconnects power to the motor and opens the unloading valve at the same time. The unloading valve should be connected to the compressor discharge line through a check valve with an unloading valve port upstream of the check valve. These valves are usually threaded into the top of the air tank as well. Sounds to me like your valve was leaking and someone bypassed it.

Coleman Powermate Model Number BV6548049, pressure switch leak.

Usually, a leak at the pressure switch unloader valve is caused by the checkvalve in the tank. The unloader valve at the pressure switch bleeds out the air from discharge tube after compressor reaches set pressure. This only takes a few seconds. If air continues to leak then air is leaking back into the discharge tube past the tank checkvalve. Follow the air discharge line from the compressor to the brass valve at the tank. The brass valve is the checkvalve that holds the pressure in the tank. There are usually two connections at this valve. One is the unloader tube to the pressure switch. Simple test for leaking checkvalve, with pressure in tank unplug or switch off the compressor and remove the small unloader line at the checkvalve(brass valve) and look/listen for leak. If leaking, remove the checkvalve and examine seat/check for debris keeping the valve slightly open. If it cannot be cleaned, order generic replacement from It will cost less than the factory checkvalve. Just pay attention to the thread sizes for easy fit. Good Luck on your repair and email if you have questions.
