PRV and or pressure switch bad?
I have a Devilbiss 80 gallon two stage compressor.
Earlier this year I replaced the 125/140 pressure switch with a new 90/120.
Yesterday during use the prv blasted off and then it would not turn back on.
Today I reinstalled the old pressure switch. It turned on and starting building pressure but the prv blasted off again at about 125.
Did the new pressure switch fail and cause damage to the prv? Or is there something else going on?
