Sump PitA sump pump is a pump, usually used for residential homes and apartments, that pumps groundwater away from the home, to reduce the water table to a level below the home's foundation. Usually, this plumbing product empties water out of a sump pit that has been created by drilling or coring through the flooring/wall of the foundation and digging out of the earth below it. Usually, the sump pump will be prompted into the action of draining the water out of the sump pit through a manual turning on of the sump pump, or when the water rises to a certain level in the sump pit. Water levels rise in the sump either through the accumulation of ground water that has saturated the ground, or through a drainage system that has been created around the perimeter of the foundation to channel water towards the sump pit.
Sump Pit Installation.
If you have already had a flooding problem in your basement, or fear having one in the future, a sump pump to reduce the maintain a low water table level around your house may be appropriate. The simplest solution to basement water is a sump pump. Most or all of a sump pump installation job can be performed on your own, with products already available, or with products (such as a jackhammer) that can be rented at local home improvement stores (like Home Depot).
To avoid encountering the foundation footing, you should install the sump pit approximately 8 inches from the basement walls. Then you may want to make a pencil sketch of the circular hole that will be drilled, allowing for approximately 6 inches around the pit. To cut through the concrete or stone flooring, you will need a jackhammer. Local stores such as Home depot or Loews may have this power tool available for rental. Cut the perimeter with a jackhammer, in 8 to 12 inch segments. When the entire area is broken, continue to drill the jackhammer at an angle until all of the concrete shards are broken up enough so that they be picked up and removed. Collect all the individual shattered elements of concrete and then place them in a bucket for removal.
After all the concrete has been removed. You should have direct access to the earth below the foundation floor. You will then begin to dig the soil. Monitor your progress using the liner. You should remove enough soil to allow approximately 6 inches of earth soil all around the liner. You will know that you have dug to a sufficient depth when the top of the pit liner sits level with the top of your foundation floor. A pit liner is a metal or plastic barrel shaped canister, that is approximately two feet in diameter by 2-3 feet deep. a pit liner would contain 60-100 Liter of water if filled.
When you have excavated enough soil to accommodate the width and depth of the liner, set the liner in the cylindrical hole, and fill the rest of the area excavated by the jackhammer with coarse gravel. A gravel aggregate of 3/8-1/2 in. in diameter will be fine.
