How to Install a Sump Pump in Your Basement:
First, bust out the concrete…
- First, you need to choose a location for your sump pit. It’s best the choose a location based on the best place to discharge the water outside of your home.
- Place the basin upside down on the floor no closer than 14” from the wall. Trace the circle onto the concrete floor with a marker. This will ensure you don’t run int your basement footing when digging your hole for the basin.
- Using a rotary hammer, drill a ring of 1/2” holes clear through the floor about 6” apart outside of the circle you drew on the floor.
- Using a sledge hammer or an electric hammer, bust out the concrete from the center out to the ring of holes. Remove the loose concrete. It’s best to have a few buckets nearby to fill up with the loose concrete and debris.
Next, install the sump basin…
- Now, that you have your floor busted you’ll need to dig the hole to fit the basin into. Dig down about 30″ from the top of the concrete floor so you can fit the basin and a bed of rock beneath it. Next, pour about a 5” to 6″ base of 1/2” rock in the hole to set the sump basin on. You’ll need to add or remove rock so the top of the basin is flush with the surface of the concrete floor. This bed of rock underneath the basin helps to level the basin with the floor, as well as, add proper drainage below the basin.
- With the basin in place, pour rock around the outside of the basin until the rock is 2” to 3” from the surface of the concrete floor. Pour cement around the basin and trowel flush with the surface of the concrete floor.
Finish by installing the sump pump…
- Now, it’s time to install the sump pump itself. Included in our DIY sump pump kit is a Zoeller 1/3HP M53 sump pump. This is the industry standard sump pump used by professional basement waterproofing concretes. Screw a 1-1/2” threaded PVC cup in to the sump pump. Glue a 8” long piece of PVC pipe into the threaded PVC cup.
- Install the check valve onto the other end of the 8” long PVC pipe. Cut a piece of PVC pipe long enough to go from the top of the check valve to 6” above the surface of the concrete floor.
- After that, put the sump basin lid in place and glue a 45-degree elbow on the PVC pipe that’s sticking up through the cover. Plumb the PVC pipe back to the wall near your sump pit. Using another 45-degree elbow continue the piping up the wall and outside through the wall to drain the sump pit to daylight.
