DIY Battery Backup Sump Pump System

Do you have city water or a well? If you have city water, I suggest a water power back up. After all a battery powered pump is not going to pump a lot of water too long before it depletes the batteries. The water powered jet pump will likely cost a lot less was well.

is youre sump higher than the street or low area in your yard away from home?

if so dig a ditch and run a line to daylight, gravity tends to be highly reliable.

a battery sump pump will require replacing battery every few years, and ideally should have a seperate drain line.

so a single point failure cant occur.

Basepump and Zoeller make city water powered pumps, batteries and chargers go bad.

You get what you pay for.

Regarding the other replies... I have installed two water powered systems that were POSs; I would want them in my house. Fortunately don't need a pump, let alone a backup, but if I did I would use a battery pump.

The "Pump Buddy" by Bur-Cam is junk, the pump works OK but the float operated water valve is so flimsy that after sitting in the off position for a few months, it won't turn on. The valve also drips water constantly.

I replaced it with a BasePump system. Works great and drains a lot of water quickly. A big plus is the fact the pump is not in the sump but above it, relieving a lot of crowding in my small diameter sump. Not cheap, but much better value than the flimsy Pump Buddy which is way overpriced for what you get.

Thanks you all for your responses...

Jack,

Do you have a battery powered BasePump system, or is yours water powered? Was it very hard to install?

Thanks again.

My Bad... I meant to ask that question to EXT.. not Jack... :)

I have the water powered pump with the 3/4" water supply and tossed out the Pump Buddy.
