How to install a sump pump
How to install a sump pump: in 16 easy steps.
- First walk the length of the floor, and try to find the lowest elevation level in the basement. If the basement does seem perfectly level, then walk the perimeter of your home, and try to find the lowest elevation of your property to try to find the right place to place the sump pit and sump pump. If you are designing a sump pump system that empties water outside your house, on the periphery of your property boundaries, you are going to want to install your sump pump near the wall of the basement.
- When you have found the appropriate location for installation, set the sump basin down on the basement floor, and mark its outline on the floor.
- Cut through and remove the stone/concrete of the floor, and place the broken pieces in a sturdy bin for removal. You may use a concrete saw blade, jackhammer, or demolition hammer to cut through and break the floor to break it into pieces small enough to pick up and remove by shovel and hand.
- You are going to cut a hole (sump pit) deep enough to be able to set the top of the basin flush with the floor. You may also need power tools such as a jackhammer to break up ground laden with rock or very hard soil.
- Put the basin in the sump pit, making sure it is level with the basement floor.
- Add a layer of gravel (several inches) to the bottom of the basin.
- Over the gravel layer, lay a stone paver.
- On top of the paver, set down the sump pump.
- Run a length of PVC pipe (also known as the first riser) vertically up from the sump pump, and connect a check valve at the top of the piping.
- At the other end of the check valve, connect a second piece of PVC pipe. This second piece of PVC pipe will be cut near the level of the wall above the top of the concrete foundation where the piping will exit the house.
- Using a whole saw, drill a hole through the house wall big enough for the horizontal pipe leaving the house to fit through. Prior to using the hole saw, you may want to draw the outline of the hole using one of the pieces of piping as a guide.
- Run the horizontal piping through the hole, with about 6 inches of piping extending outside the house.
- Next line up the horizontal piping with the second riser, and cut the interior pieces of piping so that they can fit together properly using and elbow.
- Connect the interior pieces of piping using the elbow.
- Fill in the excavated area outside the basin with concrete. Your concrete mixture will be one part cement, two parts sand, three parts gravel, and 5 ½ gallons of water for every bag of cement. Most jobs will require about 1 back of cement to complete the concrete pouring and spreading. Smooth the concrete with a pointed trowel to get it level with the original basement floor.
- Plug the pump's power cable to the nearest electrical outlet. Test the system by filling the basin with water.
