Backup Sump Pump Archives

Before my parents moved into our current house, the water heater was apparently in the kitchen. The FHA made them dig out a spot in the basement to put the water heater. So basically what we have is a crawlspace basement…with an area about 15 feet long, 3.5 to 4 feet wide, and about 3.5 feet deep that is bricked off all the way around with cinderblock bricks to hold the surrounding dirt in place. When it rains a lot (usually 2-3 days), water runs in due to the hole being “under” the ground level.

A pedestal sump pump (with motor above water level and a propeller on the bottom) has been down there since we’ve moved in…and it has been changed out with a new one a few different times over the years. One year we had a tropical storm pass right over us. It knocked out the power and that hole filled with about 1 foot of filthy dirt water, since the pump couldn’t get power to pump it out. I dipped all that crap out with a bucket that night. Dried the water heater…it re-lit, thankfully. The heating/air machine also was fine (that’s also down there and closer to the sump hole than the water heater is).

I dug the sump hole deeper after that incident – it’s about a 40 gallon sump hole now, about 3 feet across. I lined the big hole with cement (it was previously just a dirt bottom and still is in a lot of other areas). I installed a new pedestal sump pump, along with a battery backup sump pump (submersible) operated by a marine battery. However, the battery backup pump seems to have died/frozen up. I’ve looked all over for a solution online, or for a better backup pump that can pump dirty water without getting clogged and freezing up. They don’t seem to exist.

Any suggestions on a backup pump for when the power goes out? The battery backup pumps are quite horrible with dirty water. They might work well in a nice and clean sump pump in a new house…but not for what I need it to do. I know they make “water powered pumps”…but that’s not all that great, either.

I’ve been looking at APC brand UPS (uniterruptable power supply) and need to figure out what the minimum size ups needed (700,1400, etc) to power the sump pump is…

Due to 9″ of rain falling in 4 hrs., my sump pump and backup failed. I am looking for ‘insurance’ that it won’t happen again. I think the backup pump discharge outside. Has anyone used a water-powered backup pump in severe conditions? If not, what kind of “regular” backup pump do you recommend?
