The AC5 gets my vote. They'll handle up to 48000 BTU of AC. I've seen a few of the call pumps split in two and leaking water. Rodger Rollsdoc MT49PH

i've had bad luck with Cals. typically the seal on the shaft fails (the spring seems to be steel) and it looses its cooling oil. March have a better reputation... in a bind, you can use a small spa or swimming pump pool... I have one has a spare and have used it for a week at a time... works fine. pascal miami, fl 70 hatteras 53MY live cell helmcam @ www.sandbarhopper.com ----- Original Message ----- From: "Henry Dennig" <hjdennig@hotmail.com> Cc: <trawlers-and-trawlering@lists.samurai.com> Sent: Monday, August 25, 2008 10:39 PM Subject: T&T: Air Conditioner pumps > It's 80 degrees at 10:30pm and a holiday weekend is coming - so the air > conditioner pump died!.

I seem to remember that someone mentioned using a normal domestic shallow well pump for A/C water circulation. A lot cheaper (under $200) and you can grab one at the local Home Depot, Lowe's, etc. I am very happily using one of these for domestic water, but that is certainly not continuous duty.
