We're looking to get our sump pump replaced, and the guy said that we shouldn't get a battery-powered backup, as that goes out after a few hours. Instead, he said that we should use a water-powered sump pump, which runs on water, and not on any power, so it can run infinitely, even with a prolonged power outage.
Has anyone ever heard of this? Is it worth it to pay more to get this kind of sump pump?
Thanks in advance
