Well, you've already purchased. But I'll throw in my $0.02.
We live in South Texas
- we run our A/Cs a LOT. Also, I have about 45 years of experience in pumps for marine
aquarium systems. We've been through our share of March pumps. The biggest problem with them is that if they are not submerged, the cooling
channels will pretty easily clog over time, and overheating
will kill the pump
. The same with the KoolAir. We tried one. It's just like the March, and self destructs when the passages clog.
We now use an Iwaki (I see someone else recommended them) pump
. Buy the one with the Japanese motor
. Do NOT install it if you might have flameable fumes - I'm not sure it's certified for that. I've used them in really bad marine
environments for many year, with great success. Defender sells them.
Another thing we did is we put in a redundant pump. Because they always fail in the middle of the night, right? Just flip a switch and we are back in business. Swap the dead one out when we have the time.
