I then resorted to a battery powered backup pump kit from a well known hardware store which was great as it came with a 3 year warranty! But I soon realized just one year and 3 months later the backup pump is not made the same as the primary and the prop for the pump sits very flush with the bottom of the unit, which inevitably will corrode over time, really making the warranty useless in my eyes. After all, what good is a backup pump that doesn't work if it isn't used for a year?
In steps this Liberty Sump Jet! I do know how to plumb with copper well, but this was my first time with pex tubing. As long as the pex tubing is cut straight, sharkbite quick connectors are NO PROBLEM at all!
I ran a new cold water line from the 3/4" section in my basement over to the corner where my sump pit is and ran it down the wall with a 90 degree elbow and tee'd that off to a spigot so I can fill my pit for testing with city water at any time. (A great thinking-ahead-feature on my part as I've had so many failures over the years!) at the lower end near the floor I sweat'd on a copper barb for the pex fittings from there into the sump water line inlet.
Ultimately for me, my biggest obstacle was fitting the sump jet into my pit itself, just underneath my Radon Air Tight Sump Dome I had purchase for radon mitigation. I ended up using the convenient 4 holes in the sump jet with some longer threaded bolts with lock washers and nuts on the bottom side. I cut a small slice of 3" PVC to use as a support spacer between the top of the sump jet and the bottom of the sump lid, so I could keep the sump jet just a little bit lower and not entirely flush on the bottom of my sump dome lid for my needs.
This was great! Hidden out of sight. I followed the instructions and installed a reliable double backflow prevention valve to keep the sump water from back flowing into our home water supply. The pex quick connect was perfect on the sump jet for accepting the blue pex tubing and I liked it so much I got another to use in case I ever need to remove the water feed from the sump jet for any sump pump maintenance. I did NOT install just a "Y" PVC adapter as I didn't want any water flow force from my primary sump pump to be able to back feed to the sump jet which I feel could slow down it's efficiency. Again, this was done according to the instructions. A full separate discharge line out the back of my home. I just have 2 sump hoses leaving my home now instead of one and they are next to each other.
Slowly turning on the shutoff valve that I installed within 6 feet of the sump jet is handy and allowed me to allow water to flow to the sump jet while removing as much air as I could before any testing as the company suggests.
I only heard one short air pocket/thunk noise as I filled the sump pit for a full test. Surprisingly it didn't take long at all to lower the level which will keep my basement dry for many years to come! Feels very solid in construction and runs quiet itself, although I can hear the water itself running through the copper plumbing. I have not yet installed a water hammer as suggested, but plan to do as soon as I am able to.
Now time will tell, but my nerves are taking a much needed rest already, which I cannot put a price on.
Thanks so much for a great quality product!
The system works as advertised. I would not use this as my primary pump because it uses public water to run, but it's an excellent choice as a backup.
I still have to cover the pit because I have a radon issue, so you can ignore the large white pipe.
I added a water hammer arrestor and a fill valve so I can test it, so you can also ignore all the blue pipes too.
There is a one-way check valve for the water supply. That check valve is not necessary per the instructions.
There is a discharge check valve on the primary pump, but per the instructions you do not install a check valve on the JetPump because it's unnecessary and would reduce performance. Re performance, I used 45 degree turns rather than 90 degree turns. If you don't have space, I don't anticipate using 90 degree turns would be an issue, it would simply be less efficient. I had the room, so I opted to maximize efficiency.
The only expected negative is that it will require more physical space in the pit, and I will have to work on how best to seal the pit because of the radon exhaust pipe. Since I have the room, I will simply be building a box around the entire thing and using roofing rubber grommets around the PVC pipes to help make a good seal.
Again, excellent Backup System, I would still use a traditional sump pump for the primary system.

It’s not too big, nor too loud. It looks fine and isn’t too heavy. This really fits our needs! Simple and effective!

Second, since this unit is secured to the discharge pipe of the conventional sump pump I found it quite challenging to cut and fit all the pipes. There are essentially three points that need to align nearly perfectly: the discharge pipe of the back-up pump to the main discharge line, the mounting point of the back-up pump with the conventional sump pump discharge pipe, and the copper supply line. There isn't a lot of room for error. And, since the water supply uses a SharkBite fitting you need room to maneuver it into place. That's difficult with so many ridged connections.
After having done this and now understanding the difficulties, I would highly recommend using flexible PEX tubing instead of copper for the water connection. This will make installation infinitely easier.
Also, if you use ABS pipe like I did, you'll need to use ABS/PVC transition cement to connect it to the PVC of the sump pump.
Finally, make sure you add a rubber coupling to the conventional sump pump discharge because you'll want to replace that pump some day and you won't want to cut the whole mess out to do it.
All this said, the pump works just like it's supposed to. And, it's rather quiet to boot. Great peace of mind.

about worrying about being away from your home when
the power fails. You may need a plumber if you don't have
a length of 3/4 inch pipe to tap into but Mr. average can
easily do the rest.
