"What is a radon mitigation system ?" An inline blower and a vent to the outside from under the slab. Any radon is removed from under the slab and vented to the exterior. I would test before bothering with a mitigation system.

The short answer, I think, is no. Even a small sump pump pulls something like 6 amps (720 watts) so you'd need a pretty large UPS to keep on running for any period of time. From APC's runtime chart a 1500 VA back-up (retail $250) would keep 700 amps running for 5 minutes. Motors have a fairly large in-rush of current on start-up too. I don't know if a UPS is designed to handle that. The pumps sold with battery back-up systems are 12 volts DC, so you couldn't just plug one into a UPS either. It is probably far more cost effective just to buy a automated battery backup sump pump system.

I have been shopping for the best sump protection for my newly finished basement. It is 2,800 square feet and was completed to an 'above average' finish with a bar, theater, my sports memorabilia collection, etc. I live in one of the older neighborhoods in Hinsdale, IL and we are very prone to power outages. My sump pump runs every 30 minutes when dry, every 4 minutes when raining hard. But the point is...I CAN NOT FLOOD. I'm comparing several products: StormPro Platinum, PeakFlow Pumps ePump (model 5600). The StormPro product seems to simply be electric pumps powered by an inverter if the utility power fails. I'm enough of a hobbyist to know that inverted DC can't supply an AC draw very efficiently, therefore my running time would be severely limited. I also don't see ANY self testing or notification capabilities on that unit. (Incidentally, I also looked at a brand my plumber had called ProSeries, but quickly realized it was just a WatchDog (same manufacturer) like at Home Depot). I guess I'm leaning toward the PeakFlow ePump because of the twice a day testing, diagnostics and notification, performance capabilities, and comparable pricing. But before I decide for sure to purchase that one, I have a few questions that I consider crucial regarding backup pumps in this purchase: How often does the product self-test? If it does not self test, how does it tell me it has broken several years from now (since all mechanical things eventually break)? Is it able to pump over 60gpm at 10' high, run continuously for 14 hours, detect frozen or air locked pipes, diagnose bad pumps, batteries, power supplies, etc. Can it call and email me 24/7/365 with important alerts within minutes of a suspected alert condition? What redundancy is built in? Is there any kind of online interface or controls for the system? What is the warranty? Please inform if you know of any product that has all the capabilities of the Peakflow Pumps brand unit described above. Thanks! Sincerely, Ben Runkle, Principal Runkle, Caldwell, and Jordan, Ltd.

On a side note, anyone heard of/recommend the zoeller home guard for a water powered backup sump? (or is the liberty sj-10 better)? Thanks.
