I am in the market for a battery backup sump pump system. I have
searched around for best pricing, and it would seem that everything is
INCREDIBLY expensive (or so I think). I thought it was ridiculous to
pay $130.00 for a small backup pump. I guess to soften the blow it
comes with a plastic case (about the size of a cheap plastic tool box)
for a battery and some PVC piping. In addition, you have to purchase
a battery AND battery acid for $118. One system I looked at was
$246.00 for the case and pump, $115 for a battery and $17 for battery
acid. YIKES! This doesn’t include what other miscellaneous pieces I
might need. I would like to custom build my own for less. I have an
electrician and a plummer in the family… So you may ask, why am I
coming here for advice? The answer is, I would like to educate myself
first and prepare said proposal before I approach anyone for help. I
appreciate any advice on the subject. I really don’t want to spend
$500 on this project.
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
is youre sump higher than the street or low area in your yard away
if so dig a ditch and run a line to daylight, gravity tends to be
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.
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
