Q: have liberty waterpowered sump model 5710 what is the capacity on this model
by Fred R from Kentucky on March 17, 2014

A: Thank you for your interest in Sump Pumps Direct. The pumping capacity on the Liberty SJ10 Water Powered Backup Sump Pump really depends on your water pressure(PSI). Minimum required water pressure for this pump is 30PSI. At 30PSI, you will get approximately 990GPH @ a 10' head. If you water pressure is greater, your pumping capacity will also increase.
If you have additional questions, please let me know.

Q: Which is better, a battery back-up system or a water back-up system?
by Linda L from Kentucky on February 06, 2014

A: Depending on the water table in your area and the potential for flooding you could go either way. If your water removal needs are below average, you could elect to go with a low GPH rated battery backup sump pump or water powered backup. Please note that water powered systems will only work with a minimum of 20-40 PSI. They will not work if you draw your water from a well. The typical water powered system would provide between 300-1000GPH of pumping capacity. If you're in a little higher water table that the flooding potential is a bit higher, you may want to consider a battery backup system rated at between 1000-2300GPH. If the flooding potential and water table are very high, you might look at the systems rated at 2400GPM and higher. You should also check with your local municipality to make sure that they are allowed as some municipalities have outlawed them as they do waste water in a sense.

Q: Hi Jim,

I'm looking at the Liberty built SJ10 pump to work as a backup as we have had issues with water in the basement in the past. After reading some of its literature, I noticed it needs a minimum of 20 PSI of municipal pressure to work. Is there a way to check for this before ordering this product? Also it's advertised as pumping 990 gph/10'. What does this mean? In your experience is this a well built pump or are there better out there as a back-up and for similar money? I have read a few negative reviews about the float switch being very cheap and flimsy and the spring loaded check valve not operating correctly. Also, there has been a review stating it doesn't remove enough water fast enough. I'd love to hear what you think!

by Michael from Michigan on August 09, 2012

A: You might try contacting a local licensed plumber or look at purchasing an inline pressure gauge to install at your spigot that would give you a good idea of your water pressure. The 990GPH/10' means that the Liberty model SJ10 will pump water up 10 feet at a rate of 990 gallons per hour or 16.5 gallons per minute (GPM). Liberty is one of the top manufacturers of pumps in the U.S. and their product is very well built and designed. While there may be better, more expensive systems out there, we currently offer only two water powered backup systems. This and the Bur-Cam model 300402.
Depending on the water table in your area and the potential for flooding, you could go with a water powered or battery backup sump pump system. If your water removal needs are below average, you could elect to go with a low GPH rated battery backup sump pump or water powered backup.

A low output system would provide between 300-1000GPH. If you're in a little higher water table that the flooding potential is a bit higher, you may want to consider a battery backup system rated at between 1000-2300GPH.

It's Ok
It doesn't seem to keep up with the amount of water that comes into my basement. It the power goes out then my basement begins to fill up with water.
Cons: Low Quality, It Doesn't Keep Up With The Amount Of Water That Comes In

Sean,
The output of water powered backup pumps is always much lower compared to a battery backup system. You may want to consider a Battery Backup Sump Pump System, and use the water powered pump as a 3rd line of protection.

Needed A New Water Powered Backup
My old water powered backup was 14 years old and was not functional for the last year or more, maybe longer. I was going to anti up for the more expensive ceiling mounted base pump rb750, but I was talked into the liberty when a local plumbing outfit told me he's had nothing but success with this liberty sj10. I decided to go with it based on that additional nudge, the write ups here on sump pumps direct and the fact that the sj10 would be an easier install.

I also bought a new liberty 250... more

Backup Pump - Yeah
I have a sump pump that works, but I worried that while I'm away it could stop working, so I wanted to install a backup. I chose this one over a battery powered because batteries won't last forever and eventually the pump will stop. This pump is manual and runs without electricity. I tested it, it works, I'm happy and confident I won't have a flood in my basement. Price was right, free shipping, cannot beat shopping sump pumps direct. PS this shipped in two days, easy install - thanks
Pros: I'd Buy It Again, Price, Won't Find These In Home Depot Or Liwes

Liberty Sj10 Pump
I ordered this to make sure I had a back up system in my household for my own piece of mind and also for insurance reasons. Sump pump backup insurance was added as soon as it was installed. Insurance company highly recommends them now if you are in the appropriate area with the water pressure needed. Great product overall.

Did The Job
With Hurricane Sandy on the way, I installed the Liberty pump to back up my French drain w/ electric pump. Needless to say the power was out for 5 days, and the liberty took over.

It does not have the capacity of the sump pump, but it ran for 48 hrs and removed 15" of water in a large basement. Had it not been in place the water would have easily exceeded 3'.

What a great inexpensive backup!
