Hi all,

I bought my Sil Air about a month ago and it's going great until today...

The little brass pipe next to the on/off switch is constantly leaking air when the motor is switched off. When the motor is switched on the water collector has the sound of sucking air....if I cover it with my thumb it seals it and then it works fine until it hits the release valve for pressure and then it just continually leaks air again and runs the tank faster...what do I do? Sorry if what I've said makes no sense, I'm not really sure about the technical names....

Pictures attached.

It should be that check valve in the PDF.

The brass pipe under the pressure switch is the unloader valve which should open when the motor is off but should only allow air out of the compressor head, not the tank.

The check valve in that PDF determines this.
It also let's air go to the pressure switch so that's your other problem where it goes until it opens the relief valve.

This may or may not cure the auto drain issue ( are they auto?) on the water seperator but should fix your other issues.
