How Does a Sump Pump Work? [Complete Guide]

Sump Pumps are used for draining water from basements or flooded areas.

Pits below the building collect water, and when the water level reaches a certain point the sump pump gets started.

This device sucks the water from the sump holes and carries it to a spot outside where it can be disposed of easily.

The main parts of a sump pump include:

  • Basin
  • Centrifugal pump
  • Check valve
  • Float valve or sensor
  • Impeller
  • Return pipe

Before we move further with the working of sump pumps let’s discuss how many types are available in the market to help you choose the best sump pump.

Like most home gear, there are many kinds of sump pump available. Each kind has its special features.

Probably the most widely recognized kinds of sump pumps are:

Automatic versus Manual: 

In an automatic pump, the pressure sensor senses water levels increment and starts the pump automatically. 

You never worry about how to utilize a sump pump with this kind of gear since it does all the work for you. Manual pumps will possibly start when an individual turns it on. 

You may have a good model of a manual pump, yet you will likewise get water damage if you are not at your home when it started raining.

Pedestal versus Submersible: 

The distinction between a pedestal and a submersible sump pump is generally about style.

A pedestal sump pump has its engine raised over the bowl, while a submersible pump keeps the engine beneath floor level.

A few people lean toward submersible pumps since they keep the engine far out.

This model accompanies a downside, as it very well may be costlier to keep a submersible pump. Its segments are harder to reach and maintain.

Head Pressure Rating: 

This is a kind of pump that is named for its capacity to push water. While the usage quality of this pump will fluctuate from model to model. 

You can have an unpleasant experience if your pump is not bigger than your basement needs. This estimation must be over 80% of the pump’s head pressure rating.

If it is below this level, your pump is more likely to encounter failures or breakdowns.

How Does Sump Pump Work?

A sump pump is fitted in the lowest part of a basement. It is designed to keep the water out from houses during rain and floods. Its job is to keep the area under the building dry and to prevent water damage. 

Usually, sump pumps are fitted in specially made sump holes. Water flows into the sump hole by natural water flow through the soil or by drains.

The sump pump pumps the water away from buildings and keeps the basement dry.

If you are living in relatively newly constructed homes or buildings, your sump pump is probably inbuilt to a pit.

The basic function of a sump pump is to keep the basement of the building dry and prevent water damage. 

Once the water starts coming in contact with the sump pit, the pump gets activated and starts pushing the water elsewhere. These pumps work on electricity. 

A sump may be a naturally constructed pit, usually, a hole carved below the surface of your basement floor. This pit, named a basin, holds the sump pump. 

The pump is fixed with sensors that sense escalating water levels or pressure. When the water gets too high, sump pumps automatically pump excess water out of the basement and far away from your property using a release line.


Places Where Sump Pump Drain To

A sump pump drains water to a pre-decided area, like a stream or pond, in a neighborhood drain, or maybe in a dry well.

Never set your drain point somewhere close with the risk of water returning to your home. 

Preferably, keep the pump 10 to 20 feet away from the basement of your home. For the drainage of the pump, some cities have building rules so it’s always best to work together with your government.

Benefits of Sump Pump

A sump pump takes the water and pumps it away from the basements, before it enters your basement and, it is an absolute necessity in areas where the water level is high and may get higher during rain.

Sump pump systems are designed with battery back-ups to make sure that the sump pump continues to work during electricity failures or in flooding.

These pumps protect your basement against flooding while it covers the walls of your house from peeling. It reduces mold and fungus growth as well as pest invasions. 

The sump pump improves indoor air quality and keeps the basement dry for years. Besides everything else, it gives you peace of mind during rainy weather.

It’s recommended to put in 2 or 3 sump pumps or according to your basement requirement. It is better to be safe than sorry.

With a little investment in the sump pump, you get protection from flooding and are safe from the risk of water damage.

Who Needs A Sump Pump?

While the benefits of sump pumps are clear, some people need a sump pump as a necessity as compared to others. If you live in a climate that gets heavy rain or snow you need a sump pump at every cost.

If your house is built on a flood-prone plot, low-lying properties, poorly draining soil, or your house is surrounded by hills you are more likely to experience rising groundwater levels during heavy rains, snowstorms, and spring end.

How Long Sump Pump Work?

Sadly, sump pumps don’t last forever, the typical life of a sump pump is about 10 years. 

Sometimes it isn’t even the sump pump’s fault—it might be installed incorrectly, within the wrong place, and so on. If you notice unusual noises or dirt accumulation, call a plumber.

Resetting the sump pump might help in some cases. But if it doesn’t replacing the sump pump could be the only option left.

The Backup Sump Pump System

We have found some stores which offer the complete package of sump pumps which also include a backup sump pump.

Backup sump pump systems have a backup inbuilt. Consider adding a separate backup pump if you do not have already got one.

Some pumps have fancy extra features like water alarm systems — a couple of even connect with Wi-Fi so that they can send signals to your smartphone or smart home if they find an issue.

Most models work fine with a simple good-quality automatic pumping system.

Keep in mind, you’ll have to attach an extended drainage hose and increase the horsepower of the suction pump you select to compensate.

Summing Up!

Having a sump pump is a basic need for all those homes which are in the area of flooding or heavy rains.

If your house needs a sump pump you need to consider having a good one as the failure of a sump pump can seriously damage the base of your house.
