I've put an air compressor togeather with a tank.. I have one problem though.. Once the tank is pressurized and the compressor shuts off there isn't a leak down for the air pump. I have a checkvalve between the compressor and the tank but I need some sort of pressure release for the compressor pump itself so when it shuts down it will release pressure.. If you don't release the pressure the motor cant start the air pump.. There is just too much backpressure on it. Does anybody know what I can do to remedy this problem other than leave the fittings loose? Thanks, - Mike

Thanks, - Mike Many compressors have a solenoid valve that does just that, you should be able to get one from a professional tool dealer, maybe ebay or an online surplus company.

Thanks, - Mike Also check out the pressure switches, there should be some that have a small valve (like an auto tyre valve) that bleeds off the discharge line when the switch goes open at pressure.

Also check out the pressure switches, there should be some that have a small valve (like an auto tyre valve) that bleeds off the discharge line when the switch goes open at pressure. Automatic pressure switches for compressors are available with and without pressure blow-off valves. When the motor contactor releases at the pre-set pressure, there is a little lever that opens the blow-off vavle releasing the pressure between tank and pump. Good luck,

Thus spake Rheilly Phoull: Also check out the pressure switches, there should be some that have a small valve (like an auto tyre valve) that bleeds off the discharge line when the switch goes open at pressure.

Good luck, Indeed, however I had in mind the pressure switch mechanism actuating the valve. A very common feature of such when I was involved in servicing that type of gear.

Need to put a check valve between the pump & the tank, to take the load off the motor at start
