How to Install a Sump Pump Basin

How to Install a Sump Pump BasinSump pumps can be professionally installed by plumbers and other contractors. If you are brave enough and confident in your skills, here are some important guidelines.

1. Choose Sump Pump Location

Familiarize yourself with the layout of utility and water pipes under the foundation of your house when choosing the location in the basement for placement of the basement sump pump. Obtain a diagram if possible. Pump installation will require digging under the foundation and it isn’t wise to risk hitting any access or connectors.

2. Mark Location

Once the location has been picked, place the basin turned upside down on the spot. Draw an outline of the basin with permanent marker on the concrete floor using it as a guide. Make the outline about six to ten inches bigger all around than the actual basin. Chipping often occurs when digging into the floor of the foundation and can cause the opening to be larger than intended. It is strongly recommended that digging take place no closer to basement walls than 10 inches.

3. Hole Drilling

Jackhammer along the outline you drew around the pump basin. Go slowly to ensure accuracy. Once the outline has been cut, begin using the jackhammer in the middle using a smaller sized bit. You only want to break the concrete up enough to remove it. Don’t try to hammer too deeply. Remove the loose concrete.

4. Basin Placement

Use a shovel to dig the dirt out of the cleared space to make a whole in which the basin can be placed once it is sufficiently deep. There should be a space of 1 to 1.5 inches between the basin top and the dirt floor. The hole should not be deep enough for the pump basin to be flush with the ground because concrete will be used to make the basement floor and the pump basin flush.

5. Gravel Filling

Use gravel to fill the space between the basin walls and the hole until the loose gravel meets the top of the dirt hole. This should cause the basin to stand upright in the hole. If not, gently rotate the basin to allow the gravel to shift into place.

6. Smoothing

Use a trowel or wooden float to smooth the dirt around the pump basin. While doing this, remove any chunks or debris remaining from the use of the jackhammer. Rocks or debris will cause the cement to dry improperly. There should be a space of 1 to 1.5 inches remaining between the basin top and the dirt floor.

7. Cement Application

Once the dirt is smoothed and the cement has been properly mixed, use a trowel to apply the cement. In evenly spreading the cement, the pump basin should become level with the cement floor. The cement floor should be allowed to completely dry before resuming the installation of the plumbing and pump.
