“Works great, gives you the peace of mind you need if you have a flood-prone basement. I replaced a marine-battery backup sump system with the Liberty Pumps SJ10 and the decision was a no-brainer. I no longer have to worry about my basement flooding in the event I lose power for more than a few hours during a storm. This pump moves more than enough water per minute than my perimeter drains can dump into the sump pit. Install was easy, and the shark-bite fitting made the connection easy and quick. My only complaint is that since I had to mount this to a pedestal main sump pump and my check valve for it was rather large and awkwardly placed, I could not lower the SJ10 where I ideally wanted it to be. Extending the pickup tube is easy, but the float only allowed so much adjustment with the metal rod and rubber grommets. I still love my purchase and would buy another if anything ever happened to this one!UPDATE 3/1/17: Overnight we had a terrible storm. At 2 AM we lost power, fearing the worst I went downstairs to inspect the sump pit. Water was rushing into the pit and surpassing the level where the main pump would usually kick in.. I waited anxiously and sure enough, the Liberty Pump kicked in and saved the day. It had NO problem at all keeping up with the inbound flow. It's 8am, raining still, and I'm at work, but still without power at home. Had I still had my old battery backup system it would have been dead by now and my house flooded, but this Liberty Pump has me here worry-free. Now my only concern is if the power will be back up before my milk spoils instead!”
“Easy install with basic plumbing skills, works great! Would be better with an adjustable float but satisfied with unit. More peace of mind than battery backup system.”
“Easy enough to install, but 2 issues. First, it would not suck out any water until I removed the foot valve. Also, there are no extensions to lower the float and suction pipe - so in my pit the pump does not kick in until all of the drain tile is full and will only drain down to the top of the tile inlets. Called Liberty and no extensions are available. So this pump will work ok, but not as I expected.”
“This is a good deal for a backup pump. I recommend it for anyone that has a sump pump and has city water available. I wish I had it for the extended power outage here in the Northeast over Halloween.”
“Pleasantly surprised at just how easy this was to install. I have a Liberty pump as my primary electric pump but of course wanted a backup. Compared to battery backup units this unit is a champ. I wedged a 1-1/2" PVC pipe from my ceiling to the floor and fastened it to the ceiling beams to fasten this pump to because I didn't want it attached to my existing electric pump pipe. The instructions state not to "Y" the output to your main pump but I couldn't see the harm. Even thought this unit has a check valve, I added an external one anyway. I unscrewed the fitting from the pump and added a 90 degree fitting because it fit my application better, no issues. If I had one complaint, it creates a major water hammer effect when it comes on and off. I solved that by adding a separate section of PEX to handle the hammer. It comes on when water rises about 1" above where the electric pump would kick on.”
“Installed as a back up pump. Very easy installation. Only took me about an hour. Be aware however, that the recommended backflow preventer for this pump is expensive. About $170+. I consulted a licensed plumber who recommended an alternative that was much cheaper and met my local codes. The pump tested and ran great.”
“Best back up sump pump you can buy. Power went out just 3 weeks after the installation and it worked flawless for two days. I like the sure on off switch. That is the problem with other pumps that turn on and stay on. This one appears to have a much better switch process. Very Happy”
