How Often Should A Sump Pump Run During Heavy Rain? 

A Sump pump is a device that helps to collect and divert the water from your basement into an outside drainage system.

It also prevents flooding of your home by keeping the water away from your foundation walls. 

Sump pumps are designed to remove water from basements. They operate automatically when the level rises above a certain point.

The amount of time they run depends on several things, such as the size of the basement and the volume of water entering the system.

Sump pumps are usually installed at the lowest point of a home or building. This is where water will naturally gravitate to. If you live in a flood zone, a sump pump may be of use to you. 


How Often Should A Sump Pump Run?

If your basement floods frequently, you should install a sump pump. These devices work by pumping out water that enters your basement through cracks around doors and windows.

A sump pump is typically connected to a drain pipe that leads outside. It runs whenever it detects water in the basement. 

Sump pumps should run as often as needed. Once a certain water level is met, they will begin to run.

Why Is My Sump Pump Running So Often In The Winter?

The main reason a sump pump will run more often in winter than summer is because there is more ground water from rain and melting snow.

Water collects on the ground and doesn’t evaporate as quickly. When the temperature drops, this causes the soil to freeze. As a result, water expands and becomes trapped under the frozen soil.

This makes it harder for the sump pump to push the water away, as it has frozen.  Also, the pipes connecting the hose to the sump pump may be colder in winter than in summer.

This could cause them to leak more easily. All these factors will make the machine work harder. 

What Are The Different Types Of Sump Pumps?

There are two types of sump pumps: electric and water-pressure powered. 

As the name suggests, electric sump pumps need electricity to operate. As they are going to be operating by water, you must ensure there is a ground fault circuit interrupter. 

It may also be worth having a backup power supply, as flooding usually accompanies storms which lead to power outages. 

Water-powered sump pumps don’t use an electrical current to work, they use water pressure. As there is no electricity involved, they have a longer run-time.

However, they are only suitable for homes that have a high-pressure water flow. 

How To Install A Sump Pump?

Installing a sump pump is simple. All you need is a few tools, some pipe fittings, and access to a basement. Installing a sump pump involves digging a pit in the floor of your basement.

Next, you must connect the sump pump to the pipe leading outside. Finally, you must put a cover over the hole to keep rodents and other pests out.

Sump pumps come with instructions that tell you how to install them. Follow these steps to make sure you have everything you need before starting the installation process.

How Often Should My Sump Pump Run During Heavy Rain? 

When there are periods of heavy rain, your sump pump may run continuously. This helps prevent flooding in your basement.

However, it is important to keep in mind that a sump pump only works when the water level is high enough. Most of the time, the water level won’t reach the top of the sump pit.

For this reason, you shouldn’t rely solely on a sump pump to protect your property from flooding. 

How Long Does A Sump Pump Last?

Most sump pumps last about 10 years. However, some models can last even longer.

If you want to extend the life of your sump pump, make sure you are cleaning it regularly. You should also check the drainage pipes for any blockages or leaks. 

Also, avoid placing the pump near a hot tub or pool. This could damage the pump’s internal components.

Why Is My Sump Pump Constantly Running?

Why Is My Sump Pump Constantly Running

If you find that your sump pump is constantly running, it could be because there is a blockage in it. It could also mean that the filter needs cleaning.

It could also mean that your sump pump is not big enough for the area it is working in, or there could be a leak in the discharge line. 

The best cause of action here would be to inspect your sump pump and give it a good cleaning. You should check all drainage points for any damage. 

How to Stop Your Sump Pump Constantly Running

A Sump pump that is constantly running can cause issues as it will use up a lot of energy, overheat, and may eventually break. 

If your sump pump has an ‘inlet screen’ you should inspect it as it may have been clogged up with dirt. You should unplug your sump pump and check this screen for any debris.

Hose it off or brush off any visible first and plug it back in. If it is still constantly running, then you may need to call in a professional, the same goes for if there is a leak in the discharge line. 

If your sump pump is continuously running and there is no water around it, then the float switch may be stuck on the ‘on’.

If this is the case, you should unplug the sump pump, and clear any obstacles that may be in its way. 

You should then make sure the float moves accordingly and that it is unobstructed. 

What Is Causing My Sump Pump To Turn On And Off?

There are many reasons why your sump pump keeps turning on and off. It might be caused by:

  • An open circuit breaker
  • A shorted fuse
  • A faulty relay
  • A bad connection
  • A loose connection.

You can fix this by replacing the part that is malfunctioning. If you cannot find the part, call an expert plumber for help.

How Do I Know If My Sump Pump Is Working Properly?

A sump pump must work correctly every single time. Otherwise, it will not provide adequate protection against flooding. You can check whether it’s working properly by checking the float. 

The float acts as the sump pump ‘on’ button. When the water levels reach a certain point, the float will switch the pump on.

This float is normally on the side of the machine. To check whether it’s working properly, lift the float as high as possible, and it should switch on. If it does, then it is working. 

Another easy way to check if it is working is by simply dumping some water in the sump pit. If it switches on once you’ve dumped the water in and the water level sinks down, then it is working. 


In summary, a sump pump is very important in preventing basement flooding. However, it also requires regular maintenance. Make sure your sump pump is always ready to protect your home from floodwaters.
