Champion R15 stops at 30PSI no matter what
(Yuba City, CA)
I recently received a free Champion pump from a friend. His father had it out in the weather and never maintained it. I brought it to my house, miraculously, and have started to play with it.
First, the Start breaker is awfully corroded, but somehow still works.
I had the motor rebuilt, and it load tests well.
I pulled apart and cleaned the head and valves.
All of this and it still pumps up to 20 psi, acts like its going up hill, and then stops at 30 PSI.
I didn't pull apart the oil pump, should I?
I disconnected the sensors entirely, to no avail, same results. Any thoughts? PLEASE?
