What Is a Water-Powered Sump Pump?

When your main sump pump malfunctions or there is a power outage during a heavy downpour, a water-powered backup sump pump helps keep your home dry. When this occurs and water begins to rise above the primary pump’s float, it turns on automatically.

The water supply to your home will then begin flowing into the sump pump via the pump ejector, creating a powerful suction that removes the water safely.

How Water Powered Sump Pump Works?

Water powered sump pumps use the pressure of your home’s municipal water supply to create a strong vacuum that channels water up from your sump and discharges it outside your home. In contrast, battery backup sump pumps work by pushing water out of your sump pit using an impeller and motor.

An automatic valve/ejector jet unit and a float assembly make up the suction-generating pump in water powered sump pumps —the pump links to your residence’s municipal water line, suction, and discharge pipe.

Your sump’s rising water level lifts the float, which triggers an automatic valve opening that lets city water pass through the pump’s ejector jet. A nozzle and chamber inside this jet transform the water pressure into a vacuum. 

Like a vacuum pump, the low internal pressure results in a strong suction that quickly empties your sump pit as it is significantly lower than the atmospheric pressure outside.

Water Powered Sump Pump Vs. Battery-Powered Sump Pump

Both battery-powered and water powered sump pumps aid in preventing water damage and keeping your basement dry, but how they accomplish this distinguishes them from one another.

Water powered sump pumps drive the pump using water pressure to keep water out. A battery-powered backup pumps water into a discharge pipe outside after being powered by your sump pump.

Water Powered Sump Pump – Advantages

Water powered sump pumps are popular among homeowners for several reasons.

1. Low Maintenance

The maintenance and replacement of water powered sump pumps is not a big deal due to their relatively simple design. Moreover, the water powered sump pump is simple to operate due to the lack of many moving parts. 

However, you should test it periodically and carry out annual sump pump maintenance to ensure it will be functional when needed.

2. It Doesn’t Require Batteries

One of the great benefits of using a water powered pump is that no batteries are needed; as such, you never have to worry about buying new ones or wonder if the ones already in place still work. 

A battery-powered pump requires a new battery to operate every few years if it is not in use and is used even more frequently or if there are prolonged power outages.

3. Long-Lasting

A water powered pump has a 10-year average life. However, you can also extend it by up to 20 years.

Here is an easy tip to extend the life of your system: 

  • Run your sump pump until the float turns on to test it out, then wait until all the water successfully drains before turning it off.
  • Testing the system for any malfunctions.
  • Check for leaks and odd noises.

You should carry out this maintenance procedure at least twice a year for the best results.

4. Reliable

These sump pumps use the municipal water pressure in your home to pump water out of your basement if your main pump breaks down. Therefore, they will keep pumping water out of your house if you can access it.

Battery-powered pumps can only run quickly before needing a new battery. Besides, not all of them operate continuously at the same frequency, which suggests that you may need to replace them if they start pumping less water.

Water Powered Sump Pump – Disadvantages

In addition to their advantages, water powered sump pumps also have drawbacks.

1. Low Pumping Volume

Water-powered sump pumps have a lower pumping rate than other options. While battery-powered backups can remove up to 2,400 gallons of water per hour, on the other side, a water powered sump pump can only remove 1,324 gallons of water per hour.

2. Need Constant High Water Pressure

For most homes, these sump pumps’ recommended water pressure range is between 40 and 60 psi. Therefore, if your water pressure is low, it might not completely drain the water from your basement. 

Besides this, if the homeowner has a well, the water powered sump pump won’t work since it only uses municipal water.

3. Can Raise Your Water Bill

Water powered sump pumps may increase your water bill. They use roughly two gallons of your home’s water supply to pump out one gallon of sump water. 

It might become quite expensive if it needs to run for a while. And if your water powered sump pump continues to run continuously without your knowledge, it could cost you more money.

4. Takes Drinkable Water

Many homeowners are more aware of their environmental impact due to the constant, unfavorable environmental changes. Since water powered pumps need clean water to remove dirty water, many people choose the battery-powered option.

How To Install A Water Powered Sump Pump?

water powered sump pump

Although installing a water powered sump pump is more complex than installing a battery-powered one, it is still doable without hiring a professional plumber. 

Reading the owner’s manual before installing any pump will give you detailed instructions on setting it up and operating it. Since every pump varies slightly, you must know how it works.

Step 1 – Getting Started

Installing a water powered sump pump takes much time and requires breaking through concrete. Determine the location of your main water and sewer lines before you attempt to break through.

Before installing the pump, make sure the drainage around your home doesn’t have any external drainage issues, such as blocked gutters, by looking closely at the drainage system. For convenience and effectiveness, selecting the appropriate equipment is crucial. Select a suitable location for the sump pump to install.

Step 2 – Installing The Water Powered Sump Pump

Break out the concrete at the lowest point of the floor with the jackhammer. Ensure that the opening is near an exterior wall. 

Make a section that is 6 inches wider than the pit liner. The depth of the pit must equal that of the liner. Place the liner in the pit and fill it with gravel. Then seal the space between the pit and the floor with concrete.

Create a hole that is the same diameter as the discharge pipe outside the wall. After inserting the caulking gun into the hole, caulk around the discharge pipe. 

The pump’s electrical cords should be taped to the riser with vinyl electrical tape before the discharge fitting is connected and the pump is set into the pit’s bottom.

Place the pump so the float is a few inches away from the liner for simple and smooth movement. Attach the liner lid over the riser.

Connect the discharge fitting to the discharge pipe on the exterior wall using PVC pipe. Then install the check valve between the discharge fitting and the PVC pipe. The check valve prevents overheating of your pump motor. Seal the connections between the pipes using PVC cement.

Step 3 – Testing

You can now test your pump since the installation is complete. To test the pump’s functionality, add 5 gallons of water to the liner. Frequently, especially before the rainy season, run the pump for a few minutes to ensure it is functioning correctly.

Once the water lifts the float, your pump should start working. The water powered sump pump will be installed successfully without any problems if you carefully follow the abovementioned steps.

Tips For Troubleshooting And Maintaining Water Powered Sump Pump

You can take a few steps to examine and resolve the problem if your water powered sump pump is not pumping water. Here are tips to get you started:

1. The pump may require more power if it cannot draw water from the drainage system. By coupling the pump to a hose and turning on the water supply, you can check the suction power of the device. Consider adding a longer pipe or a more powerful motor to boost the suction power.

2. Verify that all connections are secure and that the pump is installed following the manufacturer’s instructions. Make any necessary repairs after checking for potential leaks near the pump.

3. By priming the pump with water and slowly releasing it into the drainage system, you can test the pump. After being primed, if water begins to leak from the pump, it probably needs lubrication or maintenance. Look for any clogs or obstructions in the drainage system, proper coupling, seal, and hose installation.

4. Check for clogged-up sediment in filters and trap arms since this can eventually result in ineffective pumping performance: regularly clean filters and traps with the proper fluids or mechanical means.

For the proper functioning of your pump, take into account the points mentioned above. However, it would be better to call a professional for assistance if it still needs to be fixed.

How To Choose A Water Powered Sump Pump

Sump pumps can drain standing water from crawl spaces and basements. Choosing the proper type of sump pump and having a water powered backup are both crucial. 

Consider the following factors when selecting the ideal water powered sump pump for you:

1. Size

The size of your basement must be considered when designing your sump pump, but its ability to withstand the force of your water supply is of utmost importance. The model you pick should handle the volume of water your sump pump will be able to remove.

It would be best if you had a sump pump that is large enough to handle the volume of water that is kept in your basement.

Most pumps rate according to the motor’s horsepower (HP) and cubic feet per minute (CFM) of airflow. The more horsepower and CFM a pump has, the more effective and powerful it is.

The “GPM” system, where GPM stands for gallons per minute, is the most popular rating system for sump pumps. 

The GPM rate can be used to calculate the number of water pumps per minute.

2. Water Capacity

Sump pumps generally have a motor and a reasonably large tank for holding water. Channeling water into the sump pump’s reservoir removes water from the house.

The size of the tank influences a sump pump’s capacity to pump water.

3. Water Pressure

Sump pumps can fail for many reasons. Low water pressure is one of the common causes of sump pump failure. This is particularly true if you live in a city with little rainfall or your water system is under high pressure. 

If you reside in one of these areas, you ought to buy a water pressure booster to raise water pressure.

4. Water Outlet

The outlet’s size is the most crucial factor when selecting a backup sump pump. A small outlet will be helpful if your basement is only a few feet deep. Nevertheless, a large outlet will be more appropriate if your basement is much more profound.

Additionally, the depth of your water level will affect the outlet’s size. A more prominent outlet will be more suitable if the water level is only 3–4 feet deep.

5. Noise Level

The noise your sump pump makes when it fails can be pretty troubling. It can be very frightening when sump pumps make a loud clicking or whirring noise late at night.

However, there are some ways to minimize noise. Ensure your sump pit has enough airflow to keep the water inside first. A fan or an exhaust fan can use for this, but it’s best to put it on a separate circuit.

Consider buying a sump pump with variable speed control. These can lower to reduce noise, which will be beneficial.

How much it costs for a water powered sump pump?

A water-powered sump pump’s cost varies greatly and depends on several factors. With installation, most pumps cost between $100 and $300. The price increases with the number of features, functions, and gallons per hour of drainage!
