Superior Pump Slip-On Check Valve 1-1/4"

Q: what does the check valve do for a sump pump and do I need one if Im buying a sump pump?

A: You definitely want to install a check valve along with your sump pump. The check valve will keep most of the water left in your discharge pipe from returning and emptying back into your sump basin once your pump shuts off, thereby preventing any rapid re-cycling or continuous cycling of your pump.
