You can hide a few air lines within your rock work. When the power goes off, the ac plug switches the battery operated air pump on. You will get many hours out of the battery. The B10 model is just an air pump, while the B11 model has the auto-activation when the power goes out.

Has anybody tested how long these puppies last before the batteries die?

Someone told me once but I forgot. It was well over 12 hours though. This model may last longer than the B11. http://www.bigalsonline.com/BigAlsUS...ybackupairpump

This one claims about 72 hours of battery life (two x D). http://www.seaquestmarine.com/Life_A...p/won_la50.htm

I have one of the double-D cell air pumps running my ATO and I am using the original batteries since I installed it early last summer. Typically it runs for 2 minutes every hour and certainly more on hot days. I think the 72 hour run time is probably accurate with a new set of duracell. Damn things are loud as hell though as they are piston driven and not diaphragm.

Ha, ha, yeah, I have the "SilentAir" B-11. It's anything but silent, however, that can be a good thing, alerts you right away when the circuit trips.

Yeah, it may not have an iphone ap, but it lets you know you have a problem

Ok ordered the Slient Air B-11

Going to buy the Champion Power Generator 3000W at costco for 275 (on sale $75 off this week). I think it should be a great back up with Costco 100% satisfaction guarantee

That combination will give you more bang for the buck. Personally, I find gas generators to be overkill and impractical (noise, space, and maintenance) but at least you are covered for a longer period of time and it's there for other family emergencies and projects. You can run the air pump for the first few hours then set up the generator if it looks like a long haul. Tell your neighbours about the sale so they don't come around with an extension cord when the power goes out
