The Liberty water powered backup sump pump starts working when your electricity goes out or your primary sump pump fails.

Yes, if your home has a basement, with a sump pit, I truly recommend that you invest in a water powered sump pump backup system. It's just not worth it to take a risk, by not having a backup system, then have to deal with hundreds or thousands of dollars of repair bills due to water damage.

Not to mention the high cost of removing mold, after a basement flood!

Having a pre-installed water powered sump pump in your basement is an ounce of prevention against the flood season

Also, don't forget: a water powered sump pump backup works by using the force or PSI of your utility water supply. So, you won't pay any additional electricity costs when your best water powered sump pump is working to keep your house safe & your basement dry!

Video - Why buy a water powered sump pump?

So you can see, by this video, a water powered sump pump backup is important to have if you have heavy spring rainfall, strong summer storms and large amounts of snow melt. Or, if you live in an area of the country that's vulnerable to tropical storms or hurricanes.

And really, with the crazy weather we've been having the last few years, just about any area of the US is vulnerable to strong storms with heavy rainfall and power outages.


How does a water powered sump pump work?

water powered sump pump

Wondering how does a water powered sump pump work?

Water powered sump pumps force water out of your sump basin, to keep your basement dry and prevent flooding.

But, instead of your primary sump pump, which gets it power from your electrical outlet, the best water powered sump pump gets its operating power from your city water supply.

So, if your power goes out, your main sump pump system will not work. But because your water supply continues to flow, even during a blackout, your water powered backup sump pump will sense when water is starting to rise in your basin. The float of your water powered unit will rise, with the level of incoming water.

After the float reaches a high level, it will automatically start your water powered backup and it will begin pumping water out of your pit, using the PSI of your city water as its power.

And the best water backup system will continue to work, uninterrupted, until your pit water level safely decreases - or your electrical primary pump starts working again.


Video - Electric Sump Pump vs Water Powered Backup Sump Pump

Wondering about the differences between an electric sump pump vs water powered backup sump pump? This video shows you:

One of the best things about having a water powered backup is that it turns on automatically when the water level in your sump basin starts to rise - but your primary sump pump doesn't kick on.

Once you make the investment & install the best water powered backup system, it stands ready to turn on. You don't have to turn it on - or be home - in order for it to work for you.


Advantages - Water Powered vs Battery Backup for Sump Pump

Let's talk a little bit about the advantages of a water powered backup vs a battery backup sump pump.

Here I'll show you the advantages of a water powered backup sump pump vs battery backup sump pump.

Advantages of the best water powered sump pump backup versus a battery backup sump pump:

  • a water powered system will continue to run for very extended periods of time as long as your city water continues to flow - think days or weeks
  • there's no pump to overheat or wear out
  • it will continue to work for you as long as you're getting about 20 PSI + from your city water
  • there's no battery to buy- or replace
  • your water powered sump pump will continue to work during a complete power outage or a brown out
  • a water powered sump pump does not require maintenance
  • because it doesn't use any electricity, you won't pay for extra electricity usage when it's running
  • the initial investment of a water powered sump pump backup is comparable to the cost of a battery backup for sump pump

Disadvantages of the best water powered sump pump:

There are many advantages of installing the best water powered sump pump, and you should consider all sump pump options, but I should point out two disadvantages:

  • if you have well water, you cannot use a water powered backup sump pump system
  • you will use more galllons of city water - that you'll have to pay for
  • right now, an average water powered backup system will pump out 1 gallon from your sump basin for every 2 gallons of city water you'll use

Ok, you've gone searching for the best water powered sump pump by reading a lot of water powered back up sump pump reviews. And you've made your choice.

Now you're probably wondering what else you need besides your new water powered sump pump. Good question!

What else do I need with a water powered sump pump?

As many of my readers will tell you, one of the best water powered sump pump parts or accessories you can get is a quiet check valve!

Seriously, putting in a new quiet sump pump check valve is an inexpensive & easy way to get rid of all the water "thud" and water "hammer" you'll hear when your sump pump turns on & off.

I highly recommend the Zoeller 30-0181 Check Valve on Amazon if you’re experiencing loud noises, hammering or clapping with your existing check valve when your sump pump is running. It’s specially designed to greatly reduce or eliminate all that annoying check valve noise - and it easily installs with only a standard head screwdriver.

The Zoeller 30-0181 has 1 ½” slip x slip unions, and you can install it vertically or horizontally!

And you can check Amazon’s price on the Zoeller 30-0181 Check Valve.

In in opinion, there's nothing sweeter than getting rid of sump pump water hammer - especially at night - by just quickly installing a quiet check valve.

How does a water powered sump pump work?

Wondering how does a water powered sump pump work?  A water powered sump pump uses the pressure or PSI of your city or municipal water flow, to operate:

Here's my diagram showing you how a water powered sump pump works.

When your primary electric pump has failed – or doesn’t operate during a black-out – water will begin to rise in your sump pit. When the water level gets too high, it will trigger your water powered sump pump float to rise.

When this float rises, it opens up a valve that allows your municipal water supply to begin flowing into your best water powered sump pump.

Your city water will flow in, full of pressure, through the pump ejector.  The rush of the city water through the pump ejector creates suction (also called the Venturi  Principal) that sucks the water out of your sump pit through your discharge line.

I hope this quick summary helps your understand how the best water powered sump pump works.

How does a water powered sump pump work?


Who should install a water powered backup sump pump?

First, if you have well water, I want to tell you that a water powered backup sump pump is not for you! You need the PSI and constant flow of a municipal water supply to activate the functioning of a water powered sump  pump.  

Well pumps don’t work during a power outage so you need a large amount of unrestricted city water or municipal water supply to operate a water powered pump.

If you have well water, you’ll want to choose a battery powered backup sump pump, instead:

I can strongly recommend the Basement Watchdog BWE Emergency Back-up Sump pump on Amazon.

When your primary sump pump fails, is overwhelmed, clogs or wears out, the Basement Watchdog BWE  automatically starts up to pump up to 1,000 gallons per hour (GPH) at 10 ft lift and 2,000 GPH at 0 feet lift! It stands watch over your basement to make sure it doesn’t become a swimming pool.

What I REALLY love about the Basement Watchdog is that it has a unique LED control panel that actually tells you what’s wrong with your primary sump pump – and what to do to fix it! Genius.

And you can check Amazon’s price on the Basement Watchdog.

If you have city water, the best water powered back up sump pump has several  distinct advantages:

It will turn on automatically if your primary electric pump is clogged or fails

And it will turn on automatically if your utility power goes out – even if you’re not home – because it needs absolutely no electricity

Because a water powered backup sump pump doesn’t need battery power, either, it will work for hours, days or weeks, if you need it, to keep your basement dry until your electricity comes back on

And the best water powered backup sump pumps need no maintenance. As long as the city water flow with the proper pressure, a water powered unit won’t quit on you.

What are the differences between a battery backup sump pump vs water powered sump pump?  

When you’re comparing a batter backup sump pump vs water powered sump pumps, here are a few pros and cons to consider:

If your primary pump fails, or you lose power, there is a limit to how long your battery backup sump pump will work.  All batteries will eventually lose power, before it needs electricity again, to recharge.

And don’t forget, even if you don’t use your battery backup, the batteries still need to be replaced every 3-5 years. Yes, a battery backup sump pump can help prevent basement flooding, but only if the batteries are fresh.

And some environmentally minded homeowners like the idea that the best water powered sump pump won't add to the overflow of dead batteries that are already in landfills. So, because a battery is not needed, some homeowners feel that a water powered sump pump is a greener choice.

But a water powered sump pump will keep working, almost indefinitely, until your electricity returns and your primary pump starts working again.

And when you’re comparing a battery backup sump pump vs water powered sump pump, you should take in consideration of the cost of installation. Since the best water powered pumps are a little more involved, to install, they have slightly higher installation costs.

And remember, if you use well water, you have to use a battery backup sump pump, because your well pump will stop working if you have a black out.

Water Powered Sump Pump Installation


Can the best water powered sump pump be used as a primary pumping system?

No!  Even the best water powered sump pump should never be used as the primary pump system in a home.

You see, electricity is very cheap. That’s why primary sump pumps run on electricity. It doesn’t cost a lot to run a primary electrical sump pump.

 In comparison, it’s much more expensive to use a lot of city water to pump more water out of your sump pit. That’s why water powered systems are only used as backup sump pumps. Yes, you’ll have to pay for the more costly city water, to keep your basement dry, in the event of an emergency, using a water powered system, but it’s still much cheaper than the thousands of dollar of damage a flood will cause.


Cost of a Water Powered Sump Pump Backup

cost of the best water powered sump pump

Wondering about the cost of a water powered sump pump backup? Let's talk about the average cost of buying a water powered sump pump backup - and the cost of using city water.

If you want to buy a water powered sump pump backup that's a good mix of quality, with a budget-minded price point, I would tell you to expect to pay anywhere between $150 - $295.  For this price, you'll be getting the best value & quality, in my opinion, for a water powered sump pump backup.

Now, when you're talking about the cost of a water powered sump pump backup, you don't have to worry about the cost of a charger, electricity or battery. So that's a savings for your home.

But you will have to pay for your municipal or city water that's used when your water powered sump pump backup turns on. A good quality water powered sump pump backup will pump out at least 2 gallons of your sump water to every 1 gallon of city water used.

You'll have to check your own water bill and calculate the price that you're paying for a gallon of water. To give you an idea, depending on your location, your price per gallon can range from .0032/gal to .007+/gal. It's rare that I've seen city water priced at more than 1 cent per gallon, but you should still check your water bill.

Factoring in the price of buying a water powered sump pump backup with your cost of city water, will give you a good idea of the cost of installing & running a water powered sump pump backup.

Water Powered Sump Pump Installation

Are you wondering how difficult it is for a homeowner to do water powered sump pump installation? Well, if you're the type of person who likes DIY projects, here is a brief summary of some of the work involved in water powered sump pump installation - to help you decide if its the right job for you. Or if you should hire a pro.

Here I want to show you where a water powered sump pump is installed inside a sump pump pit.

And you can see my top water powered sump pump recommendation: the Liberty Pump SJ10 on Amazon.

You'll need to install your water powered sump pump inside the sump pit, above your primary sump pump.

And you new water powered sump pump will need to connect to your 3/4" cold water line in your home, to work. So you'll need to cut your water line, connect your water powered sump pump, then seal the connection with fittings, tape or soldering.

The next step of your water powered sump pump installation is to connect it to your drain line. And then reseal your drain line.

Then you'll need to deal with your back-flow preventer. A back-flow preventer is a valve that keeps the water from your sump pump pit from flowing back into your drinking water supply. Each municipality has its own rules & regulations on what type of back-flow preventer must be installed, so you need to check your local codes before your start your water powered sump pump installation.

You'll need to clean & test your back-flow preventer.

Then, the last step in your water powered sump pump installation is to test it.

You'll want to simulate an electrical black-out by unplugging your primary sump pump. Fill up your sump pit with a bucket of water to lift up the water powered float & activate it. Watch to make sure it drains the water from your sump pit.

That's a quick run down on the major steps you need to take, for water powered sump pump installation, so you can decide if you want to hire a plumber instead.


Water Powered Sump Pump vs Battery Backup - what are the advantages?

Here’s a short list, for reference, of the advantages of the best water powered sump pump vs battery backup systems:

  • Extremely reliable – a water powered sump pump will kick on, automatically, when your primary sump pump fails
  • No battery to buy or replace – the best water powered sump pump system uses no battery
  • Works without electricity – a water powered sump pump kicks on & runs without electricity. So if you lose power you’ll still have a working sump pump with zero electricity cost
  • Can be mounted on the ceiling – out of the way & dry!
