Things You'll Need
Adapters or Couplings
Hack Saw or Pipe Cutter
Sump Pump Check Valve
Metal File or Utility Knife

Sump pumps were developed to pump ground water out of basements to prevent flooding. Presently, basements are required in most areas to have a drain tile. Drain tile, 4-inch corrugated plastic pipe, is ran around the perimeter of the basement. The drain tile has slits in the side that allows water to seep in which runs downhill into the pit to be pumped out. The sump pump pumps the water out of the pit. If you need to install a check valve on your sump pump then follow the directions below.
Step 1
Examine the diameter of your existing drain pipe.
Step 2
Purchase a valve no smaller in diameter than the existing drain pipe.
Step 3
Purchase couplings or adapters that fit according to the size of your drain pipe.
Step 4
Take the hacksaw or pipe cutter and cut a section of pipe to accommodate them.
Step 5
File the cut edges with a metal file or utility knife.
