A sump pump is a defense against flooding. If your house is on flat ground or in a low area, a sump pump is ideal for your home. Even if you think your home is adequately sealed, the water can still sometimes find a way to get under a door or other opening that you wouldn’t expect.

Sump pumps remove water from inside your home and drain it away from the base, so it doesn’t leak again. If you are facing a sump pump running constantly after heavy rain, then you are in the right place. In this article, I’ll describe this topic. So, Let’s start.

How to fix sump pump running constantly after heavy rain

How to fix sump pump running constantly

Here are the following ways that help to fix the sump pump running continually after the rain or storm.

Determine the location of the pump

The first point for the sump pump running continuously is the location of the pump. Ideally, the sump pump basin should be at the lowest place in your basement so that water will flow naturally there. Go through the view as much as you can and then use a level to make sure the area is sloping down. 

If possible, this stain should also be near an outside wall to facilitate placement of discharge lines, and near a GFCI electrical outlet, so you can plug in the pump. Also, verify that this location accommodates the installation of the pump discharge pipes so that they remove water to a place away from the foundation or preferably to a nearby drain if local codes allow.

Drill or break the hole where the pump will be installed

To measure the size of the hole, you will make, lay the liner of the sump pump reservoir on the floor and trace around it with a durable marker. Rent a jackhammer to divide the concrete floor inside the circle. Drill the hammer holes every two to three inches around the marked circle and use a large mallet or small sled with a masonry chisel to further divide the concrete into pieces tiny sufficient so that they can be easily picked up and discarded. Keep some type of large containers, such as a sturdy trash can, to transport broken concrete.

Install the discharge pipe

While installing concrete around your sump, it is an excellent time to open your discharge pipes. Consult the instructions for your particular sump pump to find out what size PVC pipe you will need to discharge the water outdoors.

Most likely it is a 1-1 / 2 “tube. Use an electric drill to drill a 1/4 ”starter hole above the base through the edge joist and exterior wall. Using the start hole as a guide, use a hole saw with your drill to make the end hole a drill bit size appropriate to the size of your discharge pipe, as recommended by the pump instructions.

Install Backup Pump

We know that a sump pump is electrically operated, installing a battery backup pump is an excellent way to help protect your home from flooding. Power outages can often accompany heavy rains during a storm, and if your home loses power, so does your sump pump. Don’t forget to check the latest post Best Sewage Ejector Pump.

There is also a possibility that your sump pump may not function properly. The discharge pipes may become clogged; the main pump may clog or fail, the float may become obstructed or restricted, etc. Having a backup can ensure that your basement pump is not flooded and is costly damaged.

Getting know: How often should a sump pump run

Getting know How often should a sump pump run

We have got many questions in our email be like why is my sump pump constantly running? Here are the few facts: 

  • Elimination
  • A submersible pump will not start
  • The level probe & condenser


After a massive storm or rain, hydrostatic pressure is pushing water through the floors and walls of your home. Without a sump pump, the amount of water would continue to increase, leading to flooding. However, when there is a sink, the water will flow and accumulate in the well. It, in turn, activates the sump pump, which will begin the process of removing the water. Until the time the rainwater has finally managed to drain through the soil to a depth lower than your home location, the water will continue to be pushing into the basement, and the pump will continue to work to remove that water.

A submersible pump will not start: Lack of water: 

if the tank or well runs out of water, the pump stops for safety. Check why the water supply has been cut and fix the mishap. Air buildup between the check valve and pump – Too often, when installing a submersible pump, you make the mistake of placing the check valve too close to the outlet. This favours that the air accumulates between the valve and the pump and with it the pump runs out of water inside it and loses impulse force. It recommended to put the check valve at a minimum distance of 1m from the pump.

The level probe & condenser:

The probes tell the submersible pump when to start or stop. If a probe breaks, the pump stops working. The condenser it is a white cylinder that you will only find in pumps with single-phase electric power. It is responsible for giving the necessary power to the engine to start. If the capacitor has failed, you will have to replace it with another that has the same characteristics. Make sure you have correctly connected the two cables.

Sump pump maintenance- How to know its working


The two most important thing is that you have to memorize respecting sump pumps. First of all, if the capacity of a pump is not big sufficiently for your residence, then a flood can be occur. Another point is that a sump pump is a piece of mechanical equipment, and as such, it needs to be periodically tested to make sure it still works.
