Water Leak Alarms and Sump Pumps for a Wet Winter
NOAA's winter outlook leans wetter for the South and West. Heavy rain can push water into basements and crawl spaces. A leak alarm and a working sump pump with backup are cheap compared with a flooded floor.

How to choose
1
Put alarms where water starts
Place sensors by the water heater, washing machine, sump pit, under sinks and at the lowest point of the basement. A sensor that sits on the floor in the right spot is worth more than a fancy one in the wrong place.
2
Plan for the power cut
Storms that bring rain often cut power, and then your main pump stops. A battery backup pump or a second pump on a battery keeps water moving. A deep-cycle marine battery with a high amp-hour rating runs longer.
3
Stay safe around water and power
Unplug a pump before you handle it, and never stand in water near live outlets. Plug pumps into a GFCI outlet, and call an electrician or plumber for hard-wired work or if the basement is already flooded.

FAQ
Do I need a battery backup for my sump pump?
It is worth having if your area gets storms that cut power, or if your basement floods easily. A backup keeps the pit emptying when the main pump has no power.
Should I choose a submersible or pedestal sump pump?
Submersibles sit in the pit, are quieter and suit most homes. Pedestals have the motor above the pit, which is easier to reach but louder. Measure your pit and check the discharge pipe size first.
