Liberty Jet water Powered Sump Pump Back-Up Emergency System Reviews

4.6 Rating 351 Reviews
I recently lost power 3 times in 5 days (Two due to weather and one due to a car hitting a utility pole) so I decided I needed a backup sump pump. I did not want a battery backup pump because of the limited backup window so I decided to go with a city water pressure pump. This pump comes fully assembled and is easy to install for DIYers.Just be warned that this is just the pump only and there will be an additional cost to install. It's cost me an additional $100. I used PEX and SharkBite push to connect fittings which is why the additional cost was so high. You can reduce the cost by using PVC or copper water lines vs. the PEX tubing. You can also solder copper fittings instead of using SharkBite push to connect fittings to bring the cost down. However, if you can afford it I recommend the SharkBite push to connect fittings and PEX tubing since they are super easy to install.The pump evacuates at a rate of 19.8 Gpm @ 60psi which averages 1 gallon of city water to 2 gallons of water pumped. The rate however will be affected by the water pressure. The higher the pressure the faster water can be pumped. The instructions recommend a 3/4" water line to insure there is enough pressure to run the pump. My water lines are 1/2" right from the water meter so that was not possible for me but my water pressure when tested was 75psi and works fine. The pump needs at least 20psi to work and should not exceed 100psi. If your water pressure exceeds the recommendations you will run the risk of leaks which can quickly fill your basement up with water. You will also need to purchase a check valve to prevent water from flowing backwards.Once installed it worked as advertised. It pumped water a little slower than my main electric pump but it still can keep up. I plan to test this every once in a while to make sure it's still working just in case of an emergency. My Grandmother has one at her house that has been working without issue for years. She has a tree in her yard that is always taking out the electric so it is a necessity. Hopefully mine will last a long time as well.Pros:Easy to installComes fully assembledClear easy to follow instruction manualPeace of mindCons:Additional cost to install (This cost is involved with every backup pump on the market)

So easy to hook up. I suggest u get a slotted sump cover. Most install pics I've seen have no cover installed since the pump sits over the cover it makes it difficult to install on a standard cover. Just did my first test by filling up the basin and wow is this pump quiet I hardly realized it was pumping till I saw it cleared all the water in my basin. Also be sure to install a backflow preventer my local plumbing inspector recommended the watts 9d and it seems to be working great.

It seems to be well built. I like that it's not submerged. The only reason I didn't rate it a 5 is because it took almost an hour to run one cycle.

Very happy with this backup pump, does what it claims to do. Keeps your basement from flooding.

I just finished installing this item - if you install correctly, it will do the job. My house was built on an underground stream so I HAVE to have a sump pump regardless of what the electrical grid is doing because of the groundwater. This pump provides peace of mind when I'm not around. Based on how these pumps are designed, the performance can vary greatly depending on how high you're lifting the water and what your city water pressure is. I'd imagine it doesn't work well in some cases. Luckily for me, I have a good 40-60 PSI and only about 5' of lift. Awesome product.

First pump was damaged. Replacement works great does what it's intended to do.

No expensive batteries? Lightweight, durable, and easy to install? No more worrying about a power outage or other failure of my primary pump? One quarter of the price that the local HVAC/plumbing company quoted me? Sign me up! I am a computer guy - not a plumber or builder - but I have done some work with PVC plumbing and found this easy to install. The directions about attaching the water line could have been clearer, but I figured it out and could have fixed any mistakes easily. It's not quite as quiet as the main (electrical) pump, but it's only going to be used in emergencies, so that's not a problem. If you don't have a backup pump, get this one.

This pump is awesome. I had to give it it's own discharge piping because the check valves they make for PVC systems never seem to work and the pump would always push the water back through the old electric pump I have installed in tandem.
