Key Considerations for Choosing a Water-Powered Backup Sump Pump

Sump pumps remove excess water from a basement or crawl space. However, it’s very important to choose the right type of sump pump and also have a water-powered backup. In order to choose the best water-powered sump pump for you, consider the following:

Water Supply Capacity

Consider your property’s water supply capability before choosing a water-powered backup sump pump. The water supply must be sufficient to meet the pump’s needs during prolonged power outages or heavy rainfall. To ascertain the water supply needs unique to your locality, speak with a qualified plumber or sump pump expert.

Installation and Maintenance

When selecting a water-powered backup sump pump, consider the ease of installation and continuing maintenance. Look for devices with clear installation instructions and only need essential equipment and knowledge. Additionally, choose pumps with simple parts to maintain and often inspect.

Pumping Capacity and Performance

How soon a water-powered backup sump pump can drain water from your basement depends on its pumping capability. Check the pump’s maximum gallons per hour (GPH) rating to ensure it meets your unique requirements. Additionally, look for any performance characteristics that can increase the efficiency and dependability of the pump, such as adjustable float switches or built-in alarms.

Durability and Build Quality

For enduring performance and dependability, investing in a strong, well-made water-powered backup sump pump is essential. Look for models made of high-quality materials, such as resilient plastic or metal that won’t rust. Consider pumps with strong seals and gaskets to stop leaks and guarantee the system’s durability.

Type: What Type of Pump Do You Want?

If you’re planning on installing a water backup sump pump, you have to consider a few things, including the type of sump pump that you want. Some pumps are powered by batteries or even solar power.

  1. The good ones are powered by electricity or batteries, which can be stored in your home’s power grid or in an off-grid system. But, these pumps can cost up to $600 – $800 depending on the size and power needed.
  2. However, there are also electrically powered backup sump pumps, which require little to no maintenance and can be installed at a fraction of the cost. These pumps run on electricity from your home’s electrical circuit and come in various sizes and capacities.
  3. One of the most common types of electric backup sump pumps is submersible, which is used in homes, commercial buildings, and industrial applications.


It’s crucial that your sump pump is designed for the size of your basement, but the most important thing is that it can handle the power of your water supply. You should choose a model that can handle the amount of water your sump pump will be pumping out.

The size of the sump pump is also important. You need a large enough sump pump to accommodate the volume of water you have stored in your basement.

Most pumps are rated based on the horsepower (HP) of their motor and the cubic feet per minute (CFM) of airflow it generates. The higher the horsepower and CFM, the more powerful and efficient the pump is.

The most common rating system for sump pumps is the ‘GPM’ system, where the GPM stands for gallons per minute. This is the standard measurement for most sump pumps – you can measure the gallons of water pumped per minute by the GPM rating.

Power Source

Power sources for a sump pump vary from manual wind-up to battery-operated to solar-powered. Depending on your preferences and the size of your home or office, the choice will be different for you.

For example, if you live in a house with a basement and you want to power your sump pump with a battery, then you’ll have to get a 12V car battery. If you’re looking to power your sump pump with solar panels, then you’ll need a battery charger that can charge a 12V car battery, which means you’ll need a 12V solar panel, and maybe a battery storage unit.

If you have a smaller-sized home, then you can also opt for a wind-up sump pump, which is a good choice because they’re quiet, does not require much maintenance, and have a longer lifespan than the other choices.

Water Pressure

A sump pump can fail in many ways. One of the most common reasons why sump pumps fail is because of low water pressure. This is especially true if you live in a city where there is little rainfall or if you have a high-pressure water system. If you live in these areas, you should invest in a water pressure booster that is designed specifically to increase water pressure.

Water Outlet

The most important thing to think about when choosing a backup sump pump is how big the outlet is.

A small outlet is useful if your basement is only a few feet deep. But if your basement is much deeper, a large outlet will be more appropriate.

And the size of the outlet will also depend on the depth of your water level. If your water level is only 3-4 feet deep, then a larger outlet will be more appropriate.

Noise Level: Consider the Noise Level Of Your Water Pump

When your sump pump fails, its noise can be quite alarming. Sump pumps can make a loud clicking or whirring sound, which can be very intimidating when it happens at night.

But there are ways you can keep the noise to a minimum. First of all, ensure you have enough airflow in your sump pit to keep the water in. This can be done with a fan or an exhaust fan, but it’s best to put it on its own dedicated circuit.

You may also want to buy a sump pump with an adjustable speed control. These can be set lower, which will help keep the noise minimal.

Water-powered sump pump problems

Water-powered sump pumps are an interesting technology that’s been around for a long time. There are two common problems with this type of sump pump, though: first, the water can’t be turned off once it starts flowing; and second, the pump is usually noisy. In this section, we’ll list the most possible water-powered sump pump problems, including:

  • Water power is great, but it isn’t always reliable or effective in some situations.
  • If the water level drops below the intake valve, the sump pump will not be able to generate enough pressure to pump out all of the water.
  • Water is the most common cause of electrical problems.
  • It’s not as effective as the electric one.
  • When the power goes out, the sump pump will stop pumping.
  • It’s too loud.
  • Don’t work during a hurricane.
  • Water-powered sump pumps are unreliable.
  • Do not work well in the presence of saltwater.
  • Water-powered sump pumps are not recommended.
  • Water is great, but it is not a permanent solution to flooding.


7 Quick Facts You Need to Know about Water-Powered Backup Sump Pumps:

How do I know if I need a battery-operated backup sump pump?

You may need a battery-operated backup sump pump if you live in a wet climate or in areas prone to flooding. Since most of these pumps have a very short lifespan, you’ll have to ensure that it’s properly maintained so as to ensure their continuous operation. Also, they are less energy efficient than traditional sump pumps.

Are backup sump pumps better than regular sump pumps?

Backup sump pumps are typically used in case of a power outage or when the normal pump goes offline due to any mechanical or electrical problem. They are also recommended for places with high water table levels or heavy rain.

Regular sump pumps, on the other hand, are best suited for places with lower water tables and less rain, where the probability of flooding is lower. You can also use them during times of heavy rainfall, but you need to be careful and make sure that they have adequate drainage to prevent the buildup of water.

Can a water-powered sump pump be used for irrigation?

Yes, a water-powered sump pump can be used for irrigation. Water pumps can be powered by both electricity and water pressure, so there is no problem in using them for such a task.

Is a water-powered sump pump worth it?

No, a water-powered sump pump is not necessary. In fact, they can be harmful to your home. They are a lot of work and require constant maintenance. In addition, they tend to be expensive and may require special fittings to be installed in your house. They can also be dangerous if they get blocked or fail to operate properly. Hence, you’d be better off getting a professional to do the installation for you or else look for a sump pump that runs on electricity.

How do you choose a good sump pump?

The best sump pumps for homes are the ones that are designed to discharge water in the event of a flood. The best home sump pumps should handle larger amounts of water, have a longer life cycle, and be easy to operate.

Can a sump pump be used for both flooding and drainage?

Yes, a sump pump can be used for both flooding and drainage. However, there are a few things that you need to understand:

Firstly, if your sump pump has a tank attached to it, it should be completely full before you run the pump. If you do not do this, you will flood your basement or garage area.

Secondly, if you have a sump pump with an inlet and an outlet, then you need to ensure that the inlet is connected to the lowest point of the foundation. If not, the pump will only draw water from the outlet and not from the lowest point.

Finally, ensure that the pump is wired to your house’s electrical panel and that the inlet and outlet are connected to the main panel. This way, the pump will get its power from the house’s main panel, and the water will get drained out of the outlet.


In the event of a storm or other natural disaster, your sump pump is there to save your home from flooding. And for homeowners with a pool, these are even more essential.

However, if your sump pump is old and outdated, it won’t do the job you need it to do. And it’s definitely worth spending some time and money to make sure it does what it should. So here’s our top pick for the best backup sump pump.

It’s called the water-powered sump pump by Basepump. It’s extremely portable, durable, easy to install, and offers a 5-years warranty.
