A common question that always embarrasses our mind, “How long should a sump pump run?” In this article, we have tried to simplify this question with some important issues of a sump pump. So, let’s begin,

How does a sump pump work?

how long should a sump pump run

Though a sump pump operation seems to a very technical, it works very clearly. There is a hole-like point into the ground of the basement that is called a sump pit. When the soil around the house contains too much water, the groundwater level starts to transfer the water to the lowest point. That is how a sump pit refills with water.

When the water of the sump pit rises at a certain point, the float activator automatically turns on the pump. And it starts to remove the water through the discharge pipes. There is a motor with a fan-like device that forces the water to the discharge pipe.

The discharge pipes release the groundwater in a pointed area that the homeowner points. Be confirm you are expelling the water far away from your house that the water can’t return. Besides, there is a check valve that is a one-way valve that prevents the water from returning through the pipe.

There are two types of sump pumps. One is a Submersible sump pump and another one is a Pedestal sump pump. Their operating system is almost the same except for structure. Submersible sump pumps are created to be submerged into water. On the other hand, pedestal sump pumps are created to be placed far away from water. It may damage if it comes in touch with water.

A sump pump works by electricity, but a battery backup sump pump can remove the water when a power outage happens.

How long should a sump pump run?

Usually, sump pumps remain running until the volume of water reduces below a certain point. What if there is a heavy flow of water all day long? Can a sump pump keep the basement free from flooding all day long? How much time can a sump pump run to remove excess water? It depends on the quality. A high-quality sump pump should run for almost 20-24 hours constantly. If your sump pump is not quality-based, then the pump should run about 5-8 hours constantly. So, here you can see the difference in quality.

Do you know sump pumps may run even without bad weather of heavy rainfall or snowfall? We all know that sump pumps activate their float switch according to the groundwater level. If there is no rainfall or snowfall, then why the sump pump is running continuously? There is plenty of reason that a sump pump may run for a long time. Here we have elucidated four Important reasons with some other reason that you must notice.

  •  Water from drain tile

If your house has a drain tile system, the basement sump basin may collect the water of the drain tile’s water. Also, you may have a broken sewer pipe or faulty drainage system near your basement. You don’t need a drain tile system and a sump pump at the same time. They both do the same work of removing water. But unfortunately, you have both set-ups, you should make your basement waterproof by waterproof paint

  • Return of the water

Make sure you have pointed to a safe area for water discharge through the sump pump. The place must be far away from your house. Otherwise, the water may come back to the house through the discharge water pipe. The soil will absorb the water, and as a result, the water will go back to the sump pit. So, always make sure the water is not returning to the house.

  • Broken underground water line

There is plenty of underground water line around every house. The line may break for a different reason. If the water line breaks, the soil will absorb the water, which emerges because of the broken water line. That may cause the increasing water level of the sump pump. You can test it by shutting off the water line for some time or examining the presence of chlorine. If so, then immediately fix the problem with the help of a plumber.  

  • Your home is near a water movement area

If your house is near a massive pond or a lake, your basement is below the water level. That will cause the excess supply of water into the sump pit, and the sump pump is supposed to run all the time. In that case, we prefer not to build a basement. Besides, there may be a flow of water underground of your house for a certain season or for all the time.

  • Other reasons for sump pump running constantly

If a sump pump runs for a long time to remove excess water in the rainy season or while the sump pit accumulates water for different reasons, it is all right. But if a sump pump is constantly running without having enough water to remove, there must be a problem with the sump pump. The problem must be taken on action, or else the pump may burn out or damage. Some common reasons are why a sump pump may run even the water level is low,

  • If you do not install a sump pump according to your sump pit size, the pump may not work properly. A sump pump that is too small according to the size of the sump pit, may not clear the excess water quickly. So, it remains turned on to remove the excess water. The solution is you can reduce the sump basin depth as if it contains less water or you can exchange the size of the sump pump.
  • There is a check valve into the discharge pipe that ensures not to return the water through the discharge pipe. If The check valve is broken, the discharged water may return through the discharge pipe.
  • A clogged discharge line may be the reason for running the sump pump for a long time. A clogged pipe will obstruct the water that the sump pump pushes. If water cannot discharge, the pump will run constantly to remove the water.
  • The pump float switch may be stuck for some reason to turn on position. That is a reason a sump pump may run all the time even the sump pit has not enough water. This is a sign of sump pump failure.
