“if you want to keep the fizz in your pop of a 2 liter bottle through it's entirety use the fizz keeper. By pumping air into the bottle until it feels tight it prevents the pop from being able to go bad and start losing its fizz. Have been using these for years successfully.”
“I could not be happier with this product! It's earily quite and gives me piece of mind. My main pump recently broke and it took nearly an hour to repair it; however, I didn't even have to turn this backup off due to the fact that it calls for a separate outflow. My main runs between 1500 and 2000 times per day and we've tested this backup and it passed with flying colors. I wish that they made a main pump!”
“Good pump, but inflexible in terms of float level, water intake levelI installed this pump in March 2013.Here are some install tips and comments.1. While the instructions said to have a separate drain line for just the pump, I thought that was unneccesary. Here is how I set mine up: With the primary sump pump on the bottom of the pit, run that output to a one-way check valve, then to a sanitary T-fitting that is upside down. From the horizontal end of the T-fitting, install a long sweep 90 degree elbow and run that up vertical. That needs to run up to two rubber 90 degree elbows that loop into the exhaust outlet of the Liberty pump. The other end of the upside down sanitary T-fitting gets run off to the storm sewer or outside discharge point. I chose to use the rubber elbows because I didn't want to commit to gluing up the Liberty pump outlet and realizing that I'd done it wrong (you do have to glue in a few inches of pipe to give the elbow something to clamp onto).The one-way check valve allows the Liberty pump to operate without pushing water back through the primary pump. The only negative to this setup is that you get a large volume of standing water above the one-way check valve that you have to drain in order to work on the system. You will likely get wet.2. I did install a Watts 009 reduced pressure backflow preventer. After that, I ran the 3/4" PEX line to a Sharkbite shutoff that is outside the pit, then to a T connector that is right at the edge of the pit. On one side of the T, I added a second shutoff, then ran a short pex line to the sump pit. This line is used to fill the pit in order to test that backup sump pump is working. On the other side of the T, I installed another Sharkbite shutoff, then a water hammer arrestor, and finally the Liberty pump itself.The beauty of this setup is that you no longer have to run a garden hose into the sump pit to test the backup system.Note: When testing the pump with this configuration (the sump pit filler and the pump are on the same line), you will find that your pump will not 'work' while you are filling the pit. You have to turn off the filler so that the pump has sufficient water pressure to activate (duh).3. I had initially wanted to install this unit inside the sump pit, in a tandem configuration, so I could still use my existing single-hole sump pit cover and have everything nicely below ground. Plus, if any of the water powered connections of the Liberty pump failed and started to leak, most of water shooting out would be contained within the sump pit itself, instead of (and ironically) flooding my finished basement.However, the Liberty pump is not adjustable in terms of the depth of the intake pipe, nor the depth of the float. It they had been, I could have done the install as I wanted. Additionally, the pump outlet of the Liberty pump protrudes horizontally more than I'd like, which makes it difficult to fit into the sump pit at all (any my pit is 18" at the top).This inability to have the Liberty backup pump lower in pit also becomes a factor when you want to test that the backup pump is working properly. My basement french drain lines are above the level of the primary pump, but below the level of the Liberty sump pump. This means that I have to add enough water to completely fill the entire french drain system before I can verify that the Liberty pump is working correctly. Water is fairly cheap, but this is annoying and wasteful.As a result, I had to install the Liberty pump on a 2x4 board above the sump pit, and construct a custom cover that would accommodate the new holes introduced by the Liberty backup pump. I chose to used pressure-treated wood to avoid mold issues.A more confident plumber/DIYer could have done the materials much cheaper than expensive Sharkbite fittings ($20 per 3/4" Sharkbite shutoff!) that I used, but I am willing to pay more for the Sharkbites because: 1) I suck at soldering, 2) if you make a mistake, you can easily fix the PEX/Sharkbite connection, and 3) Sharkbite fittings have never leaked on me.Overall I am very happy with my pump and its function. I've only taken away one star due to the Liberty pump unadjustability.”
“Installed in about four hours along with adding supply line and this was my first time plumbing. Tested it and it worked great. Gave it a four star because I want to see how it does when it's needed.”
“The unit itself installs easily to the existing main pump vent pipe. It's a bit of a job to cut the extra holes in the sump cover for the float rod and pickup tube, and tying in the new discharge pipe to the old. Running the water pipe is easy if you don't have finished ceilings, and really easy if you use the new quick-connect fittings (although pricey). Unit seems solid and well made. All-in-all not much more work than putting in a battery backup, and no battery worries.”
“Works but doesn't keep up with the water. In fairness to the product my basement has a severe water problem. I think it would work fine for a normal basement”
“This is a great and reliable back-up... much better than the battery operated one I had. My battery unit only lasted a short period and the battery died and couldn't recharge because there was no power.”
“WOW! What a lifesaver. We installed this as a backup to our regular sump pump so that when power goes out our basement does not overflow. Plumber charged about $120 to install this. We have had no issues with it nor do we need to worry about water issues in the basement while we are away if the power went out.”
