Experiencing basement floods during power outages? We have the solution – a backup sump pump! Keep reading for all the information you need to choose the best product for your home, including complete reviews of our top 8 picks for water-powered sump pumps.
Choosing a Water-Powered Sump Pump
It is important to know what to look for when choosing a sump pump for your home. Here are some factors that you will want to consider:
Amount of Water
All sump pumps have a maximum amount of water they can pump out per hour, so it’s important to know how much water you may need to discharge. Several factors will affect this amount of water, including how often it storms in your area.
Noise and Vibrations
A sump pump that creates a lot of noise can be problematic in two ways. The volume of noise can be annoying of course, but a noisy sump pump most likely vibrates a lot as well, potentially causing some vibration damage. If noise may be a factor in your situation, you may want to consider more quiet models of sump pumps.
Basement and Sump Pit Size
When researching models, keep in mind the size of your pit. Some water-driven sump pumps will work only in smaller basements. Knowing the square footage of the basement will save you from buying the wrong pump.
Another important factor to consider is backflow prevention. Most sump pumps come with a backflow prevention feature. The main purpose of this feature is to stop the contaminated sump water from getting into your fresh water supply.

Water Powered Sump Pump vs Battery Powered Backup
When it comes to evacuating sump water, water-powered pumps are the most popular option. However, electric-powered models are more cost-effective, efficient, and environmentally preferable.
Still, both systems are affected by the height of the discharge line. That is why electric pumps employ bigger motors. The water-driven models need more pressure to remove more sump water.
The Installation Guide
Installing a water-powered sump pump maybe a little bit more difficult. That is why we have prepared a set-up guide for you, breaking down the process into a few simple steps.
Step 1: Positioning the Backup Sump Pump
Positioning is important because you want the backup pump to activate only when the main system stops working. The backup water-driven pump should be placed on the wall next to the pit. Attach two three-foot-long cleats to the wall then, attach the pump to the cleats.
Step 2: Cutting Into the Water Supply
The layout of the pipes is determined by the layout of your basement. However, you should cut into the cold water line nearest to the sump pit. Solder a 3/4 inch T-fitting to the pipe you cut.
Step 3: Cutting Into the Drain Line
Once the pump has been connected to the cold water line, you must install a drain line. After you have drained the water, tighten the clamp.
Step 4: Testing
Now, take out the backflow preventer to check if there are any clogs inside. Then, reinstall the preventer. Finally, fill the pit with water, plug the pump in, and test it.
