Those are the ones you see most when you Google. Since I already have a sump pump with a float, how do they work? Do they have a float? If power goes out, do you turn it on so it will clear the pit? Thanks for any insights.
I think the most straight-forward way is to replace your existing pump with the battery backup model. It keeps charged off of house current, but kicks when the power goes out. Styles vary, but most models should use a float-type mechanism just like your current unit.
By the way, I don’t know about your own yard, but when we lived in a wet part of northern Illinois on a small acreage we found that sending the pumped water farther back in the yard made a huge difference, otherwise you wind up recirculating the same water.
