Question about sump pumps???
How much would it normally be to add a battery back up to an existing sump pump? Any other info is appreciated too.
To get a battery back up AND have someone put it in (recommended) would cost between $600-$800. There are also the hydronic (water-powered) pumps that have become pretty popular, but keep in mind that even though you're not using electricty you will run up your water bill when it is used. These, installed, run about $400-$650.
They are comparable. Brandwise, go with Zoeller for the battery back up and Liberty if you choose the hydronic.
Get some free estimates from some plumbers before you decide on anything. The way your current set-up is might decide waht would be best for you.

There are a few different ways of doing this. Ideally a guy would have 2 pumps. One that would run on 12 volts DC and one that runs on 120 AC. The 12 volt one is wired through a relay circuit so that it will only come on when the power to the 120 volt one is not available. The battery (deep cycle) remains on a charger/maintainer at all times.
If you have a 120 volt motor on your pump now you could switch it to 12 volt and run it through a 120 volt AC to 12 volt DC converter. Again a relay circuit would prevent the motor from drawing power from battery.

The last time I priced this sort of thing was with the pump and the back up as a package deal at Lowes.
I seem to remember the product was around $300.00 give or take a little.
I think you can also add just the back up to your existing pump for a little less.

They now make a back up pump that runs off city water pressure. needs no electricity.
