Q: What is a water pump alarm?

A: Water alarms are made for monitoring water leaks, overflowing or broken sump pumps, leaking hoses, and any other way water may become a danger. So how does it work? A water alarm simply detects water where it’s not supposed to be and notifies you when it’s present.

Q: Is a sump pump necessary?

Q: What do sump pump systems do?

A: A sump pump is a pump used to remove water that has accumulated in a water-collecting sump basin, commonly found in the basements of homes.
