Sump Pump Accessories
Check valves, float switches and controllers, alarms and monitors, backup batteries, discharge hose kits and basin covers that keep a sump system working.
Most sump failures start with a part, not the motor: a stuck float, a leaking check valve that lets water fall back into the pit, or a dead backup battery. A silent check valve stops the slam of a swing valve, and a replacement float or a piggyback switch can bring a working pump back.
An alarm or Wi-Fi monitor tells you when the water is rising before it reaches the floor, which matters most in a basement you don't see every day.
Start with your situation
Water drains back into the pit
Check valves stop the water in the pipe falling back after each cycle.
The pump's switch failed
Replacement float switches and controllers plug in between the pump and the outlet.
You want to know before it floods
High-water alarms and Wi-Fi monitors warn you when something goes wrong.
Your backup needs a battery
Deep-cycle batteries for battery backup pumps.
Getting water away from the house
Discharge hoses and fittings, and basin covers.
