Sump pumps usually last for years without any significant problems if given proper attention to it. When problems do occur, don’t panic. Sump pumps are relatively easy to repair. Most of the sump pump repairs can be done by yourself.
Let’s take a look at how to install or replace a check valve for your sump pump.
Installing a new sump pump check valve
To install a new valve, slide one flexible coupling over the pipe that connects to the pump and another over the pipe that connects to the drain. Insert the valve with the direction-of-flow arrow facing away from the pump. To reinstall a valve after reversing its direction of flow, slide the coupling over the pipe stubs on the valve and tighten the straps.
Adding a sump pump check valve
To add a check valve to a line that doesn’t have one, purchase a valve no smaller in diameter than the existing drain pipe and any required couplings or adapters. Use a hacksaw or pipe cutter to cut out a section of pipe to accommodate them. Deburr the cut edges with a metal file or utility knife.
