Sump pump help
(lemmy.world)
Recently had an addition put onto my house, new part has a basement which has a sump pump. But doesn’t have a battery backup.
Is it possible to add a backup pump system like this 
? In the same well thing or do I have to replace the whole pump for one like this 
which looks like a 2 in one?
Should be able to add a battery backup.

And if you can swing it, I'd honestly throw another small pump in there for redundancy.
