The prices for back-up power supplies that designed for use with home computers are becoming cheaper than dirt. I was wondering if I could use one (with the right VA rating)with my 1/4 hp sump pump. The UPS would probably only provide power for a few cycles, but it's better than nothing.

Does anyone have any experience with this?

It would be a shame if you skimped on a power supply to something important as a back-up sump pump. These pumps are designed to be used with a 12 Volt battery. Your idea is not bad, but you would be changing the engineering of the design. Would you use this type of power supply to start your car? Good Luck.

I'm not sure where 12 V comes in...

At present, my sump pump runs on 110V wall current and has no battery backup. With the transformer cube of the pump plugged into the UPS instead of directly into the wall outlet, any voltage step down should be taken care of.

I'm sorry, I misread your 1st post. I thought you had 2 sump pumps. One that runs on 120VAC and 1 that runs on 12VDC. If your area is prone to outages, then I suggest you install a battery operated backup pump. A common name brand is Ace in The Hole. You can actually install the BOP on top of your existing pump. Use your existing pump as your main pump to remove water. In the event of a power failure, the water level would rise to operate the BOP.
