It’s a wonderful piece of equipment, but there are some limits and even restrictions. Continue reading to learn more about the benefits and drawbacks of water powered sump pumps.

One of the primary advantages of a water powered sump pump is that it doesn’t rely on electricity to function. This makes it ideal for homes that are prone to power outages, as well as those in areas that experience frequent storms or flooding. In addition, since water powered pumps use natural resources, they are generally more eco friendly and sustainable than other options like a battery or gas powered models.

On the other hand, there are also some disadvantages to consider when thinking about a water powered sump pump. For example, these pumps only work well at lower levels – if your basement is prone to flooding because of an excessive groundwater table level, a water powered pump may not be enough to keep your home dry. Additionally, water powered sump pumps cost more upfront than other options and may require additional maintenance over time.

If you’re considering a water powered sump pump for your home, it’s important to weigh the pros and cons carefully. In some cases, these pumps can be a great solution – but they’re not right for every home. Talk to a professional to learn more about whether a water powered sump pump is right for you.

water powered sump pumps tackle your home’s municipal water pressure to create a strong vacuum, let out water up from your sump and quickly discharge it outside your home.

Before we move ahead let’s have a look at one of the best water powered sump pumps for your home. Battery backup sump pumps that use a motor and impeller to push water out of your sump pit.

What are the principles of operation for a water-powered backup sump pump?

The water driven sump pump effectively removes gray water from a sump pit with the help of city or municipal water pressure. It’s a secondary pump that doesn’t require any power but can move up to around 1200 gallons per hour. When your primary pump goes down due to a power outage or failure, it protects your basement from flooding while maintaining drainage.

Everything you need to know about water-powered sump pumps

Since its introduction several decades backup sump pumps have gained popularity as an alternative option for batteries-operated emergency backup sump pumps.. A flood protection system can protect your basement from flooding during power outages or secondary sump systems in the event of a power outage. Water CommanderTM water based sump pumps are increasingly used for emergency backup and reversible power-saving applications, owing to its high performance. This article focuses on a variety of topics.

Benefits of water powered versus battery backups

Backup sump pumps offer several advantages. Water pump pumps don’t lose the power they need to pump at lower pressures. Battery backup sumping pump has an elapsed run-time of 5 to 7 hours and more if used intermittently. The water powered pumps have an alternative energy source: the municipal water pressure in the house. It is possible to rely upon them when it needs pumping at a high rate. Unless your battery backup runs well for some minutes, the pump could quickly slow down or die once the battery is full.

Best water-powered backup sump pump

The best backup sump pumps are Water CommanderTM. The Water Commander ultra-efficient model MG36 pumps a maximum of 1-2x more efficiently than high-end battery backups. The MG22 Pump is one of the most widely-recommended pump in America. Water CommanderTM pumps have a high performance and high durability construction to ensure you don’t experience a leaking problem common in cheaper pumps. In the below 1-minute film Water CommanderTM pump speeds are around 40 gallons a minute in a 60-PSI pump.

What is a water powered backup sump pump, and how does it work without power?

A water powered backup sump pump uses the pressure of city or municipal water to power itself. It’s connected to a home’s main water supply line and has a check valve that only allows water to flow in one direction. When the float switch activates, it opens the check valve and water flows into the pump. This pressurized water then turns the impeller, which creates suction. The suction pulls water from the pit and up through the discharge pipe, where it’s then ejected out of the basement.

Water powered pumps provide backup for emergency situations in a home that is damaged or is unable to function. Whenever the water begins to rise below the primary pump’s float, the pump starts to operate automatically. The ejector of the pump then starts supplying water for the sump pump which will generate a strong suction which will safely drain the water.

How do sump pumps that run on water function?

When the main electric pump fails, the sump pit water level rises and reaches the float switch of the water driven pump. The valve at the water pump opens as a result of being opened by a switch triggered by the float switch of the water driven pump. This method gradually constricts city water into a jet, drawing up and expelling water from your home’s sump. Around it, there is a low pressure region, causing sump contents to be sucked up and discharged via the house’s drainage system.

Doesn’t require batteries

It has a battery and water-powered power supply that eliminates the need for replacement batteries, and you don’t even have to worry to purchase any batteries. If you have an old pump that has a battery you will have to replace the battery every couple of years to keep the battery going if you haven’t used it.

DIY Installation

Installing water pumps is not easy like using batteries. When you are attempting to install pumps, the owners’ manual is the best guide to installing and using them. It can sometimes be tricky for a user to understand their pumps and the way to perform their work.


Water pumps are typically 10 years old. This is what you can do in a short period by adding a sump pump to it for a complete cycle to ensure you get rid of all the excess. Check for clogged sump pumps and other odd septic system problems.

Low maintenance

A sump pump has a relatively simple design and has no moving parts that must be replaced. However, you can test this once per month and perform annual water pump maintenance to make sure the water is functioning when needed.

Installation Kits

The Basepump model RB750EZ comes with a special Do-It-Yourself Installation Kit that includes all the necessary specialty parts needed to build the pump, including 2 easy-to-install pipes.

Low pumping volume

The water pumped sump pump can be pumped less efficiently than other alternatives. It can remove 1.6 gallons of freshwater each hour while battery power-backups remove 2400 gallons.

Advantages of a Water Powered Sump Pump

1. Water supply is quite constant.

In the event of an emergency, water supply is typically more dependable than electricity in your region. Power outages are more common and last for lengthy periods of time, especially during calamities.

2. Pumps powered by water can operate indefinitely.

A water powered pump can operate indefinitely as long as there is water pressure. Unlike a battery that runs out of power in a day or two, a water powered pump can run for as long as you need it to.

3. They’re basic and rarely break down.

Water powered pumps function for a lot longer than battery backups. These pumps have a basic design that makes them easy to maintain and last for decades as long as you follow the manufacturer’s recommendations.

4. You don’t need to buy new batteries for them.

Batteries, no matter the kind, must be replaced after a few years of use. There’s really nothing to replace if you have a maintenance free pump with a water powered pump. This makes it even more environmentally friendly.

5. There are no hidden fees until the cycle is complete.

The machine consumes no water until it begins to operate, which only happens when your primary pump fails. Even if you don’t use them, batteries discharge slowly on their own and are automatically recharged. It’s unlikely that you’ll notice a difference in your monthly bill, but it might add up over time.

Water Powered Sump Pump Disadvantages

1. Pumping capacity is decreased

Water powered sump pumps have an average pumping capacity of just 1000 gallons per hour (GPH). In comparison to battery backups with capacities ranging from 1000 to 2400 GPH.

2. Requires a lot of pressure.

To function properly, most machines need at least 50 to 60 pounds per square inch (psi) of water pressure. The typical household’s normal range is 40 to 60 psi. If you live far away from the booster pumps for your city’s water supply, the pressure might be insufficient. If many people in your neighborhood utilize it at the same time, the pressure will undoubtedly drop, and the pumps may not work as expected.

3. High water bills may be the result.

There have been cases when homeowners have reported high water bills due to faulty pumps that ran nonstop without their knowledge. By checking in on your pump and performing basic maintenance, you can avoid this from happening.

Because of the dangers that come with using these pumps, they are unlawful in certain regions. It’s critical to double check with your local code or a plumber to ensure your safety. There are several reasons for this, including:

  • Water backflow – Backflow of sump water into the city water line is a concern in some cities, which has prompted authorities to ban water driven sump pumps.
  • Pressure in your region has been reduced – When it uses drinkable water to operate, the amount of water inside the city water line decreases, lowering pressure. This can lead to difficulties in obtaining supplies for regions further away from the source.
  • More water is added to the streets as a result of this. – When the main storm line and street are both at capacity, water powered sump pumps not only drain gray water from sumps, but also pump clean potable water.
