I thought I solved the forward A/C unit’s problem yesterday by reverse flushing fresh water thru it and cleaning out the strainer. It worked fine yesterday after that. But the circuit breakers tripped twice this morning indicating the problem was still with us!?!?

I ran a gallon of this stuff through a “closed loop” for about 90 minutes. Followed by two flushes with fresh water.

Hopefully this keeps us going this time! If not, a new unit is in order, about $2500.
