Examining
Check Valve
The check valve pushes compressed air into the
tank and prevents it from flowing back toward
the pump. The diaphragm in the check valve can
become damaged, twisted, or dirty and cause
the valve to leak or prevent the compressor from
pressurizing.
Eye injury hazard! Always
wear safety glasses when
handling pressurized air
system.
