Water powered is best but with power outages if you have a 240 Well you
have nothing. www.zoeller.com or www.basepump.com.
They outperform battery in every way with good city water. Batteries
last 4-8 years, what if power goes out and batteries last 3 minutes,
plus they just dont last in Gallon Per Day or gpH.

But you have not determined if you need a pump yet, if house will leak
at all or is it possibly gutters , downspouts , grading, etc are wrong.
Turn it off and see what happens after a few days, you likely have a
fairly nearby water table but it could be runoff. Find out water table
depth. Not running it might make basement humid, ok in winter, but maybe
level is below floor leak point on average and only needed March through
June, You pay alot to pump out the water in Kwh. You can raise level and
shutoff point, it is your experiment depending on your water table .
