How does A sump pump work in A Basement?

Here we have explained the working process of a sump pump in a few steps. If you read those steps, we assure you that you will not face any confusion about how does a sump pump works in a basement.

Usually, a sump pump is placed into the sump pit (Submersible pump). A sump pit is a hole or basin into the basement floor. When the water level touches a certain point, the basement sump pump turns on automatically. There are several pipes connected with the sump pit that discharges water from the sump basin to a spotted area. The pipe is spotted away from the house as the water can’t return to the home. Also, the discharge pipe has a check valve at the end of the pipe. It is a one-way valve that prevents the water from flow back to the sump pit.

Have you ever think how does a sump pump turns on automatically?

There is an amusing process of turning on the pump. The pump switches on the power through a float activator arm, or sometimes it’s called the pressure sensor. When the water pressure dispenses more than the air, the pump activates. There is a motor with a fan-like device inside the pump that pushes water to the discharge pipes. There are also manually operated pumps. Those pumps have to turn on by someone. But there is no security from flood while it will come. You may get out of the home or sleeping, and the pump is not turned on. It may cause dollars of damage although the presence of a sump pump. That’s why an automatic sump pump is more preferable.

The sump pump that we mostly use in our house uses a centrifugal pumpAs the pump turns on, a screw or fan-like device named impeller turns on. Using centrifugal pressure, the revolving impeller pushes water to the sides of the pipe and generates a mild-coercion area at its center. The basin’s remaining water fills the empty area, and the impeller’s spinning system pushes the water toward the discharge pipe.

Now, it comes to the discharge pipe. The sump pump’s discharge pipe can be connected with the water sewer, utility line, or drain. Some people set up the discharge pipe away from home with a long hose pipe. If you discharge the basement water into a lawn or open place, make sure that it is far away from your house. Otherwise, the water will get back to the house. And make sure your neighbors have not faced any trouble with the basement water.

A sump pump runs with the power source of electricity. So, it doesn’t need different wiring. But one thing that you must aware, you should have a ground fault circuit interrupter (GFCI) on the power outage to prevent the possibility of electrocution. As the sump pump is an electrical device, it won’t run while there is no power source. It sometimes happens during a heavy storm. So, what should you do? It may cause potential damage in some minutes if you are not able to run the sump pump. To prevent this situation, you can buy a backup sump pump that must provide backup battery power. When the electricity occurs, the sump pump will turn on with backup power. It will protect your house from the risk of flooding.

Why we need a sump pump?

If they do not install a sump pump in their basement sump basin, the risk for flooding will be very high. Besides the damage of essential things in the basement, excess water may cause structural damage. So, installing a sump pump will be an excellent decision for those persons whose house area has significant flooding concerns.

Sump pump maintenance tips

Usually, sump pumps turn on when the water level reaches a certain point. But unfortunately, that doesn’t happen sometimes. That will be a smashing case if your installed sump pump stops working. To prevent this situation, regular checkup and maintenance is a must. A sump pump should be checked up every couple of months and in the early spring. Here we have given some essential tips to maintain sump pumps.

  •  Check the power line: Check the pump whether it is plugged into the ground fault circuit interrupter (GFCI) outlet or plugged out. Make sure the power cord is in good shape. GFIC breakers may trip down. IF you see any problem with the GFIC, you can reset it.
  • Open the cover of the sump pump pit: Open up the cover of the sump pit and look inside the basin. If the remaining water looks greasy or oily, the pump motor may have some problems that must repair.
  • Check the discharge pipe: Check the sump pump discharge pipe’s connections whether they are joined properly or not. Make sure the pipes are not blocked with larger rocks or something else. Sometimes the pipes are frozen for cold weather. If so, then clean them.
  • Test your pump: Sump pumps must test if there is no rising water for a long time. Open the sump pit and pour some water at least as if the water can reach a certain level. If the sump pump turns on automatically by pouring water into the basin, then your sump pump is ready to pump the excess water. If the motor doesn’t turn on automatically, then there might be a float sensor issue that must repair.
  • Clean the sump pit: Don’t forget to clean the sump basin if there is any debris, mud, or rock after checking the float switches, float valve, and float arm.
