Choosing a Suitable Location
The process of installing a sump pump is fairly simple; however, the basin and pump must be placed in a workable spot in the basement. An ideal location for a sump pump unit is an area close enough to an outside wall, out of the way of obstructions.
A GFI outlet must be within reach, and plumbing must be easily routed to the basin.
Digging the Basin
To dig a hole for the basin, the concrete floor around the basin area is jackhammered away, and a hole is dug in the ground beneath. The hole is usually dug about six inches wider than the opening of the basin to ensure the unit fits properly and can be leveled and secured with cement.
If the unit will pump water from buried drainage pipes, that plumbing is run to the basin before the hole is filled. When underground plumbing has been connected, the hole is filled with dirt and cement, and the basin is leveled, so it's flush with the rest of the floor.
Installing the Pump
A pump is installed by first connecting the discharge pipe or hose. Some pumps are lowered into the basin and set on the bottom (submersed pumps).
Others (pedestal pumps) are mounted outside the basin and are activated when the water triggers the float as levels rise. After the pump is secure, the discharge pipe is fed through the outside wall.
The opening is sealed with caulk, and the pump is ready to use.
