Vacuflush Head Problems

[margarita jane]

Hi...need ideas, please...
had some plugage in aft head and cleared that also snaked line to vac.pump and seemed to be cleared. Pump would not run, checked voltage at pump(OK) and jumpered vac.switch and pump seemed to run and sound normal. Could discharge line to holding tank be plugged? or is vac. being held in vac.tank(inlet line still plugged) satisfying vac.switch so pump wont run..(is there a way to release vaccum in tank? or could it be just failed vac. switch? any ideas or help much appreciated.

pressure switches are known to fail
remove both wires from switch and short them together and if pump start running replace switch

Yup...Mine did the opposite...wouldn't shut off..It was the sensor.
