If your sump pump doesn't have any kind of protection, it will be vulnerable to backflow whenever there is a water main break and your system loses pressure. Backflow, which is the unwanted flow of dirty or used water flowing backward into a clean water source, is both unsightly and unsanitary. 

Having a sump pump check valve in place helps your pump to work effectively, preventing backflow from occurring and contaminating your water supply.

What Is a Sump Pump Check Valve?

While your sump pump helps drain water out of damp areas, especially in lower levels of your home like the basement, a sump pump check valve is there to keep that water from flowing back down into the sump pit.

Without the valve, if the sump pump ever turns off, the water that's left in the pipe could flow back into the pit. A functioning valve boosts your pump's efficiency and protects your system by making sure the water moves in one direction only — away from the pit and your home. 

Installing a new valve is usually fairly straightforward. All you need to do is cut through the drainage pipe to add one. If you do have a sump pump check valve in place, it's important to regularly check it and replace it whenever it gets damaged or corroded. If you're installing a new sump pump, that's another time when you'd want to install a sump pump check valve. 

Types of Sump Pump Check Valves

Just like there are various types of sump pumps — submersible, pedestal, floor sucker and water-powered — there are also different types of check valves:

  • Ball/swing combination check valves: This valve is ideal in areas that you don't have a lot of space. It features backflow prevention along with an in-line shutoff.
  • Swing check valves: Typically, these valves come in either a slip or slip with unison and compression connections variety. 
  • PVC solvent weld swing checks: This valve is similar to the PVC compression swing check. The only difference is that it has solvent weld ends instead.
