Do you know who I can contact with technical questions?
Also can you tell me what does the valve check does? My compressor builds to 70psi and stops. I find no leaks. I can turn the regulator up to 120psi and it works, even though I only have the 70psi on the tank.
For model number 919167620
Hi Jonathan, thank you for reaching out. We believe the check valve is designed to prevent air from bleeding out of the tank and back into the inlet line when the compressor shuts down. If your compressor is not filling up to the limit, then the pressure switch, part number FIX9875338, may be faulty and you may need to replace it. Before replacing it, we suggest checking if the pressure gauge is calibrated correctly or not. We hope this information helps!
