Of course, a battery backup system will help you pump the water during primary pump failure due to power outages.
But the problem with a backup sump pump is its prop sits very flush with the bottom of the unit. As a result, it will inevitably get corroded over time. And what good is the backup pump if that doesn’t work and fails to serve you for a year?
In such a scenario, a water-powered backup sump pump like the Liberty Pumps SJ10 comes into play. It requires no electricity to operate. The SumpJet removes 2 gallons of sump water per 1 gallon used, which seems a lot less but it’s enough to lower the sump pit level to keep the basement dry for many years to come!
Turns out, Liberty SJ10 is easy to install (as it comes fully assembled), reliable, and requires a little maintenance.

It’s an emergency backup sump pump which you can install just above the primary sump pump to remove water during main pump failure. In other words, you can’t use it as you use your primary pump. The SumpJet can only pump clear sump water only.
When it comes to longevity of this pump, I bet you can barely find a water-powered pump like this that can outperform it in terms of durability. Most parts of the pump body use plastic material as construction. So, water won’t affect it by corroding and it will serve you for a million years.
Simple! It comes fully assembled. What you need to do is just choose the placement and make the connection.
In short, mount the sumpjet to the existing discharge pipe using the hose clamps. Then, hook the SumpJet into the existing municipal water supply line with the help of SharkBite. Finally, connect the SumpJet discharge pipe to the existing discharge pipe.
I already published a complete guide on Liberty SJ10 Installation. Check out the article and learn how to install SJ10 like a pro.
The performance I got while testing the pump for the first was heart-winning. I filled up the sump pit from a garden hose and it didn’t take long to lower the level which will keep my basement dry for years to come.
According to Liberty Pumps, it removes 2 gallons of sump water per 1 gallon used. In simple words, the pump uses approximately 1 gallon of water to evacuate 2 gallons of water from the sump.
However, SumpJet’s pumping performance will vary with inlet water source pressure and pumping head or elevation. For example, this water removal pump can remove 11 gallons of water per minute at 20 PSI if the head lift is 4 ft.
For a better understanding, take a look at the following picture:
SJ10 is designed for minimal maintenance. It doesn’t require elbow grease to maintain the sump pump. Operate the unit manually once a month to ensure proper operation. Also, check the float for proper mechanism and clean the float if there is debris on the float or the suction screen.
I love Liberty Pumps SJ10 for a lot of reasons, including- its long-lasting construction and reliable performance. Unlike the battery backup sump pump, it’s made of plastic material. As a result, this pump won’t be affected by water and you can use it for years.
Second, its performance. It will save your basement from water damage during power outages and pump the water out of the pit like a charm.
