Best Water Powered Sump Pumps

They run very efficiently and are low-maintenance as well, which means that there is very rarely any problems with them.

If you experience abnormally large amounts of rain or if your electric sump pump starts working improperly for one reason or another, your water-powered sump pump automatically begins to work so you don’t have to be there to turn the pump on or off. If you’re looking for the best water-powered sump pump, it is good to become familiar with them first.

What Is A Water-Powered Sump Pump?

A water-powered sump pump is a backup pump only and there are two main types: water-powered and battery-powered. These pumps are installed in your home and are meant to take over for your already-installed electric sump pump if the power goes out or something goes wrong with your main sump pump.

The main requirement is that it has to work off of your city’s water system so if you rely on a well for your water supply, a water-powered sump pump won’t work. The pumps are designed to automatically begin working when they need to and most will sound an alarm to let you know that it’s on and doing its job. The best water-powered sump pump will almost always have these features.

Why Buy A Water-Powered Sump Pump?

Everyone who has an electric sump pump needs a backup pump and water-powered sump pumps are specifically designed for that job. In fact, because these pumps work on water, they would be too expensive to run as a main sump pump, which is one of the many reasons why they are used only as backups. They can also be used in homes with or without a full-perimeter drainage system or a French drain. Backup pumps such as those that are water-powered simply make life a little less stressful because you won’t have to worry about your home every time that the power goes out.

If you live in an area that is especially rainy or prone to disasters such as flooding or hurricanes, a backup sump pump is a must. Your main sump pump, which is run on electricity, will work continuously unless something goes wrong, such as the electricity going out. When this happens, your backup water-powered pump will take over. Most of them are low-maintenance, are very efficient and powerful, and have very few things that can go wrong with them. In other words, they are very reliable products.

How To Choose The Best Water-Powered Sump Pump

  1. Basement And Sump Pit Size

Although most water-powered sump pumps are lightweight and small, they do come in various sizes. Many backup sump pumps are made to be installed in a very high place such as the ceiling, which makes it even more important that they come in a compact size. The size of your basement and sump pit will help you determine which size to choose but it is good to know that there are many sizes to choose from.

  1. Amount Of Water Expected

Just as they come in different sizes, backup sump pumps can handle different amounts of water per hour; fortunately, this information is always included on the packaging. It’s important to pay attention to this information because the pump that you end up purchasing has to be able to handle the amount of water you’re expecting.

  1. Noise Prevention

Backup sump pumps can be noisy or quiet, although most of them are not extremely loud. Some people prefer a louder sound because they want to know when the pump is operating while others expect their sump pumps to be whisper-quiet. Fortunately, you can easily test them out so you can determine which one will work best for your home. Many pumps also sound an alarm once they start working so you’ll always know when they are in use.

  1. Cost

Much as with other products, water-powered sump pumps come in a wide range of prices. Most cost between $150 and $300 but the most expensive ones are not necessarily the best and the cheapest ones are not necessarily substandard. It is more important to research the features and the efficiency first and consider the price to be just one component of your final decision.

  1. Peace of Mind

Having said all this, it is also important to remember that you need to purchase a sump pump that can best do the job in your home, regardless of its features or its cost. After all, power outages can occur at any time and you need a reliable, long-lasting backup sump pump so you don’t have to feel tense or nervous every time that it rains or storms.

Advantages: Water-Powered Versus Battery Backup For Sump Pumps

There are pros and cons to both water-powered and battery-operated backup sump pumps even though both systems push water through the pipes at a very high speed, then empty the suctioned water into your sump pit. The pros of a water-powered pump include:

  • There is no battery to monitor or maintain.
  • They can potentially run endlessly and for a very long time.

The Pros Of A Battery System Include:

  • They are versatile and can be used in most homes.
  • They are super easy to install.
  • They are extremely powerful.

In fact, some battery-operated sump pumps can accommodate 3000 gallons of water per hour, which makes them very valuable. Both water-powered and battery-operated backup sump pumps are made to be efficient and reliable but they differ somewhat in their capacity to do their job, ease of installation, and the requirements when it comes to the type of plumbing system you have.

Since water-powered sump pumps require no battery to operate, they are perfect for landlords, vacation home owners, and people who spend a lot of time away from their homes because they work consistently and reliably every time.

What Are The Differences B/W A Battery Backup Sump Pump Vs A Water-Powered Sump Pump?

Besides how they are operated, there are several differences between a water-powered and battery-operated sump pump. Water-powered pumps are driven by the water pressure in your city’s water system so they can essentially run indefinitely, making them perfect for those multi-day rain storms or floods. Of course, water-powered pumps can only be utilized by homes that have access to municipal water so they aren’t appropriate for homes that run on well water.

Of course, because water-powered pumps are directly connected to city water, it is crucial that they are installed correctly, which sometimes requires a professional plumber. Battery-operated pumps are a little easier to install; however, they have limited operational time. In addition, you also have to pay attention to the life of the battery, which usually lasts from three to five years in most cases.

As you can see, there are advantages and disadvantages to each type of backup sump pump. The first thing that you’ll need to do is prioritize the things that are most important to you because this is the only way to ensure that you get the backup sump pump that works best in your home.

Water-Powered Sump Pump Buyer’s Guide

  • Town Water or Well?

Once again, if you have well water, you aren’t able to utilize a water-powered sump pump because these pumps are meant only for other types of plumbing. If you have a city water line, however, the pump will work great; in fact, it is often considered the best type of backup sump pump to have when you use municipal water.

  • Measure Your Water Pressure

Water-powered sump pumps work with a reliable city water supply that achieves at least 20 PSI of water pressure. You must therefore check the brand of pump you choose to make sure that the PSI it accommodates fits within these recommendations. If you have any questions, you can contact the manufacturer and find out if that particular pump will work in your home.

  • How Does It Work?

Essentially, there is a float in your main sump pump. When the water rises and causes that float to also rise, it signals the backup pump to begin working. A valve will then open, which sends water through the pump ejector so that it can discharge water outdoors in a safe manner. It is not a complex system but it is an efficient one nonetheless.

  • Gallons Per Hour (GPH)

All water-powered sump pumps accommodate a certain number of gallons per hour, which is why it is important that you estimate how much rain you are expecting to receive throughout the year. You always want to make sure that you get a sump pump that can handle the amount of water that you think you’ll be experiencing and this is not that difficult to do.

  • Efficiency

Naturally, all sump pumps run efficiently, including the water-powered ones, but checking the manufacturer’s description is the best way to compare various sump pumps so you can make sure that you get one that meets your needs. The GPH (gallons per hour) rate is one of the best ways to ensure that you get an efficient system in the end but you should compare all statistics to make sure that you get the right one for you.

  • Installation

Each backup sump pump takes a certain amount of knowledge to install but most of them can be installed within a few hours even if you’re not a professional plumber. Again, it is important to check the description on the package because this is the best way to determine whether you can install the pump yourself or you’ll need the help of a professional plumber.

  • Drainage

The ability to properly drain the water into your outdoor area is an important function of your water-powered sump pump so researching this aspect of the pump is important. You have to make sure that it can drain the amount of water you’re expecting and the only way to do that is to do your due diligence and research the pump itself.


Water-powered sump pumps are great backup pumps for homes that have access to city water and they are efficient and more powerful than you might think. Because they are powered by water and can essentially run indefinitely, they are great for homes that are left alone for long periods of time. Determining which pump is best for your needs is easier if you conduct a little research online because comparing different pumps is essential if you want to make sure that you get the right one in the end.

You don’t have to feel overwhelmed when trying to find the best water-powered sump pump because the information on all of them is out there and it is easy to find and easy to understand, providing you with the details that you need to make the best decision
