Description: This is located on the side of the pressure switch. If your valve is attached to your switch by inserting through a hole on the side bracket, then this is your style. Order this if your valve is broken. If this valve leaks continuously after it shuts off, then don't order this, order a check valve on the check valve page. It backfeeds this valve when defective giving a false sign that this needs to be replaced.

Poor performance, or does air leak out of the intake air filter while the unit is running? This is probably the problem. Damaged/sticking valves is a common issue when you have low compression, and can also cause the motor/engine to stall and too much pressure in the pump’s crankcase. Be sure to clean the head and cylinder very well so as to remove all of the old gasket material and build-up (carbon and rust) when re-installing.
