Air Escapes Safety Valve

[Wayne Dahl]

When the air pressure reaches 150psi the safety valve on my Rigid OF45150 opens and the compressor continues to run. Does the Safety Valve need replacing or the Pressure Switch or what exactly is my problem?

Most likely it is your check valve. Pull it out and check for a broken "keeper" inside. They corrode and need replacing. (replace the whole valve). To get the small line off, push in on the brass ring(where the line goes in) while pulling out on the line. To reconnect to the new valve simply push line back in. It works the same as a "Sharke bite" for plumbing. If you are unsure, go to Home Depot and look in the plumbing dept and you will see how it works.(display) Good luck.
