The best water-powered sump pump can be a great backup sump pump for all primary water pumps. If you live in an area that is run by a well-fed water source can opt for a battery-powered backup sump pump. A perfect example of a battery backup pump that can be used by households is the Zoeller Aquanot Sump Pump.

However, a battery-powered backup sump pump will not be a great fit for a house that is run by city water or municipal water.

Therefore, such households should make use of a water-powered backup sump pump. This water pump makes use of the municipal water pressure to drain out the excess water from the sump pit. The BASEMENT WATCHDOG Cite-33 model seems like a perfect battery-powered backup unit.

A sump pump has a stable run time and is reliable in all conditions. This means that the machine can pump water at a fixed rate in any condition as it does not depend on any kind of power. On the other hand, a battery-powered backup pump can diffuse water at a higher rate. However, the rate might fluctuate once the battery runs out of juice.

No-Power Pump

A water-powered sump pump has the unique advantage of not requiring power or electric supply for it to run. This means that the sump pump makes use of the water pressure from incoming municipal water. This creates suction using the venturi principle and thereby pumping the excess water out of the sump pit.

No Additional Cost

The water-powered sump pumps run on city water pressure and do not need to be charged or run on power. When the water supply enters the house and creates suction using the venturi principle, the sump pump drains the excess water from the sump pit. The pump water along with the municipal water is ejected out of the house.

The system in which the water pump works does not add to the electricity bill of the household. The only cost that the pump acquires is that of the cost of city water. This is much less compared to the cost that would be required to clean a wet crawlspace or basement.

Moreover, the cost of buying a battery can be around $200 with the battery acid. Nonetheless, using water-powered pumps does not lead to pitfalls while disposing of the old batteries. The user does not have to worry about repair or replacement of any pump component.

Types of Water Powered Sump Pump

There are a few types of water-powered sump pumps depending on their use and area of installation. The buyer might be able to decide between the different types by going through the basic function of these water pumps. These are pedestal and submersible water-powered sump pumps.

Pedestal Sump Pump

A pedestal sump pump is a water powered sump pump, which is also known as an upright sump pump. It is installed on a pedestal to keep it out of the accumulated water. A pedestal sump pump works with a similar mechanism as a water pump. It has a hose that connects the pump with the sump pit and it drains the excess water when the float rises.

Pedestal pumps are cheaper than submersible pumps. Moreover, they do not require heavy maintenance and are less prone to damage or breakdown. This is because they are not installed inside the pit. However, these units are not effective in case of heavy flooding.

A pedestal sump pump comes easy on the pocket, is easier to maintain and repair, and has a higher life expectancy. However, in case of a heavy flood, these units can get clogged or burn out due to overheating and operates with a loud sound.

Submersible Sump Pump

A submersible sump pump operates with a similar mechanism, but this water-powered sump pump is installed inside the sump pit. This means that the sump pump can get submerged under the water level and this might lead to the damage of the motor. Thus, these pumps are available with water-sealed motors. Moreover, the water also prevents the sub-pump from getting over-heated.

A submersible water-powered sump pump has a more powerful motor that enables it to deal with heavy floods. Moreover, the pump installed below the water enables it to operate with minimum sound. However, there are consequences of being submerged in water.

Submersible Sump Pump

The life expectancy rate of a submersible water-powered sump pump is less than that of a pedestal sump pump.

A submersible pump might last for 5-15 years in comparison to 25-30 years for a pedestal unit. Moreover, submersible backup sump pumps are also expensive.

Therefore, it is essential on the part of the buyer to decide what is the specific need for which the water-powered backup sump pump is being bought. If the need is for tackling the heavy monsoon seasons or the torrential floods in the area, then a submersible unit would be perfect. The Superior Pump 92900 can be a perfect example of a submersible unit.

However, if you are considering buying a water-powered backup pump for the frequent power outages, a pedestal water powered sump pump would be enough.

How to buy the Best Backup Water Powered Sump Pump? [Ultimate Guide]

There are a few factors and features that are needed to be considered before buying the best water-powered sump pump. The buyer should be mindful of these factors and look for them in the product description. Moreover, these features must be present in the water-powered sump pump model that the buyer decides to buy.

1. Float Switch

It is the switch that switches on the pump automatically after getting triggered by the float. There are three kinds of switches namely a tethered float switch, a vertical float switch, and an electronic switch.

THE BASEMENT WATCHDOG Big Combo CONNECT Model CITS-50 1/2 HP Primary and Battery Backup Sump Pump System with Smart WiFi Capable and 24 Hour a Day Monitoring Controller

A tethered switch works with a bulb that floats up. It turns the pump on, and then the bulb drops after the excess water have been drained out of the sump. A tethered float can reach depths leading to longer rest periods for the sump pumps. The BASEMENT WATCHDOG Big Combo Connect Model seems like a perfect example of a total pump system.

A vertical switch makes use of a rod that is connected to a switch in the housing of the motor. The pump switches on or off with the help of this motor. A vertical switch is ideal for narrower sump pits.

An electronic switch switches on the water pump when the topmost sensor alerts the water level. It switches off when the bottom-most sensor cannot sense water anymore. An electronic switch is not affected by the debris suspended in the water, as the other two types of switches.

2. Gallons Per Hour (GPH) in a Water Powered Sump Pump

This is one of the crucial factors that is needed to be considered for spotting the best water-powered sump pump. The GPH of a water pump refers to the amount of water that a pump can shift in a given period of one hour. The buyer should also remember that the higher the horsepower of a pump, the more powerful it is in draining water.

There is a range of horsepower options that the water-powered sump pumps come in like 1/4HP, 1/3HP, 1/2HP, 3/4HP, and 1 HP. Moreover, there are other considerations that the buyer needs to check for like the measurement of lift that the pump provides. Lift refers to the height between the sump pit and the highest discharge pipe that can be permitted by the pump. This is one of the metrics that should be carefully analyzed.

A water-powered backup pump might come with considerably high horsepower and around 900 GPH. However, the measurement of lift that comes with such power might be 1 foot. A 5 feet or higher measurement of lift might be accompanied by less GPH.

Therefore, it is important to note the water per hour along with the number of feet to which the pump can lift the water. A model with too low horsepower might end up getting overheated. 1/2 HP can be considered as optimal power for all situations.

3. Water Powered Sump Pump Material

The material, which forms the housing of the pump should be rust and corrosion-free. This means that the housing might be made out of alloy metals, stainless steel, cast iron coated with epoxy, and other kinds of plastic or polypropylene. However, buyers should avoid sheet metal as a housing material. The cast-iron pump system Wayne WSS30VN seems like a perfect example.

4. Pipe and Fittings Of Your Water Powered Sump Pump

This is a pump accessory that will also contribute to the efficient operation of the pump. The fitting should be compatible with the water-powered sump pump that the buyer is using. The pipe should fit the discharge outlet. The buyer should also remember here that a pump works more smoothly with wider pipes.

5. Check Valve

It is a valve that prevents the water in the pipe from falling back into the sump pit when the water pump is switched off. In case the primary pump comes with a shutoff valve, one must buy the backup. Make sure it comes with an extra valve as the former might be damaged due to corrosion from prolonged exposure to chemicals and minerals. The valve is situated on the discharge water line.

6. Sump Cover

In case your sump pit does not have a proper cover, you might consider buying one. The cover will protect the pit from dirt and debris that might clog the pump and hamper its operating ability. Buyers might also get a vent tube for the efficiency of the pump.

7. Water Alarm and Chord in A Water Powered Sump Pump

Water powered sump pumps come with a water alarm that triggers a loud ringing sound in case of some programmed situations like sump overflow. Nowadays, alarm kits are also available, which makes the user aware by calling or texting them. Moreover, a water-powered sump pump best works with a chord of the required length. Using extension chords should be strictly avoided. The PumpSpy PS2000 seems like a perfect example.

8. Backflow Preventer in A Water Powered Sump Pump

This is one of the most crucial factors that have to be considered while buying the best water-powered sump pumps. The backup pump selected should come with an enabled feature of a backflow preventer. Meaning, as the backup pump works with the help of water pressure, there are chances that the sump water might mix with the clean water.

Such occurrences can lead to a warning from the plumbing inspector of the area. You might end up buying a preventer kit or remove the pump. Therefore, it is recommended that the buyer selects a model that has a backflow resisting mechanism like a vacuum breaker.

How to install a Backup Water Powered Sump Pump?

The installation system of a backup pump is another consideration that the buyer needs to analyze before going in for the purchase. If you are confident with the installation process, then you can go for it. Otherwise, it is recommended for the buyer to take professional help from a plumber for the job.

Installing a water pump requires a connection with the household water supply. A suction pipe connects the sump with the pump and another discharge outlet drains the water out of the house premises. The suction pipe also has a screen attached to it at the bottom.

This screen filters out the debris from the sump so that they do not enter the pump. The pump also comes with a valve that ensures that the water does not flow back to the sump. Moreover, such a valve comes with the dual function of preventing the sump water to get mixed with the clean water.

The buyer should be mindful of the fact that the float of the backup pump should be placed above that of the primary water pump. Such positioning is followed to ensure that the secondary pump starts working only when the primary water pump has failed or stopped working.


How much water does a backup water powered sump pump use?

An average backup sump pump uses 1 gallon of clean water to drain 2 gallons of water per hour. The cost incurred in regards to the clean water is minimal in comparison to the cost of drying a basement.

When shall a battery-powered pump be considered?

A battery-powered pump shall be considered if you live in an area infested by flash floods or torrential floods. A battery-powered pump comes with a more powerful motor with enhanced water-shifting abilities. Moreover, a battery-powered pump might save you insurance money.

How long does a water powered sump pump last?

A water-powered secondary pump has an indefinite run period and can last for around ten years. However, it is crucial on the part of the buyer that proper care of the unit is taken while installation and afterward.


These are the factors and features that are to be considered while buying the perfect water-powered sump pump for your house. There is a wide range of options available in the market. Moreover, with a choice between the submersible and pedestal pump types, the entire selection process might seem difficult. However, after going through this buying guide, the buyer will get the much-needed clarity to strike a fair deal. It should also be remembered here that the life expectancy of the product, depends on the process of installation. Each product might come with a different installation process. Therefore, it is important on the part of the user to go through the product manual before installing it. Wishing you all the best. Happy Purchasing!
