About a week ago, I walked down into the basement to check on my laundry only to find a large puddle of water on the floor. We had temporarily fixed the pump that brings the water from the basement up into the septic but it seemed to have broken again. We need pumps for appliances below our septic tanks because the water does not have the ability to move from low to high (high being the location of the septic tank; low, my basement) without an external system doing work on it. Because of gravity's natural pull downwards, water wants to go down. To go up the pump must create power to do the correct amount of work to push the water up into the septic. Without it, the water overflows the location of the pump and floods the basement.
