why does my drain pump on a Mastercool evaporative cooler run so often?
Since the system has been up and running for this summer; the drain pump is draining the reservoir several times a day. I serviced the Master cool swamp cooler; changed the pads, cleaned the reservoir, cleaned the supply and drain pumps, oiled the bearings, tightened the belt, etc..
I was thinking it may have something to do with the older pads. New pads and clean water donâ€™t seem to have any effect on the drain pump cycling too often. It did help with the quality of cool air though.
The power to the drain pump is unplugged. Hoping to keep track of the running hours and drain it manually until I find what is causing the short cycles.
