About fifteen years ago I replaced my AC units in two cabin
areas that were supplied by one pump that was wired in a manner to pump cooling
water at any time either compressor was on. At the time of this replacement I did not reconnect a system for my pump to be activated by the AC compressor, but I switched on the pump separately before turning on the air conditioner. I've had no negative results by this plan. Some might point out that you may have the water filter basket clog and need cleaning
more frequently, but I have not found that to be a problem. I would add that I've had my March water pumps last for over 15 years of much use, while those pretty and bright polished Taylor or Cal
pumps that I tried for a while only lasted about a year each.
