With all the heavy rain in the midwest this spring, our old pump was going off every minute or so. I investigated to see how much water was coming in. There was a lot, but the real problem was that 1/2 the water being pumped out was backflowing into the sump after each cycle. Did some research and learned about check valves, which we apparently did not have, and realized that our 10 yr. old pump was basically 20 yrs. old since it had been doing double duty. After lots more research, we decided on the Liberty 257. The reviews are excellent and there were no mentions of the switch problems that seem to plague the Zoellers. Not to mention the price and warranty are better. It's been installed for about a week now (hardest part of that was cleaning out the sump basin) and is running well. The old pump, while extremely dependable, was also extremely loud, as was the noise of the water rushing back into the pump without a check valve. Being as how the pump was right under our bedroom, I was losing a lot of sleep, both from noise and worry. Now I can barely hear it (and just worry about not being able to tell if it's running or not.) Much less water comes out the discharge and it seems to run a very short amount of time. That being said, it seems to be keeping up OK.
Update: We think we figured out the issue. The float differential (the difference in inches between the "on" level and "off" level) is only 3.5" on this pump. Most pumps seem to have a greater differential than that (and thus pump out more water at a time.) This pump is working great with heavy use, but consider this before you buy.
Update #2: Came back and updated my rating to 5 stars. We just had a torrential overnight rain the likes of which I've never seen and the pump was awesome! The water was pouring in so fast, the water would come within a few inches of the top of the basin before the pump could cycle on, but when it did, it emptied it completely. Wow! It's like it rises to the occasion of abusive conditions! :) Thank you, Liberty!

Great pump. It's literally silent. The vertical float keeps the water level low. I just replaced a 13 year old machine that didn't burn out, just simply needed a new switch. I've fixed that unit and it's working, I just bought this one to use and keep the old one as backup. Get it, you'll love it.

I was torn between purchasing the Zoeller M57 or saving a few $ and buying this pump. So far, I am glad I went with this one. It has a rugged build and is incredibly quiet. You will only know if it is on if you are directly above the sump pit. I have only had it for a month so I cannot comment on reliability which is really the ultimate test. But all of the signs(rugged build, quiet, energy efficient, smooth acting switch) are pointing to longevity.
I wouldn't hesitate to recommend this pump.

Another factor worth mentioning was the solid packaging it arrived in. No worries about damage incurred while shipping! It was well protected which is always good when you are looking for a piece of equipment that has such an important role.

Well, this review is going to be 2 fold, and also a work in progress.

When looking for a solid sump pump option that wouldn't break the bank, I came across this liberty pump 257 1/3 horse power pump on Amazon. I had never heard of the brand, however that does not mean a whole lot since this is the first pump I've ever bought. It has really great reviews on Amazon.com, which to me was a sign of a good deal and good quality. When something has over 100 5 stars, and only 2 1 stars, I assume that is a reflection on the products quality.

When the pump arrived, it was a breeze to hook up and get running. I was honestly amazed at how quiet this pump is when running. I could barely tell whether it was pumping or not, even standing in the same room. I also replaced the check valve at the same time, which probably helped the lack of noise as well. Also, the pump zipped through all the ground water around the house. After just about 10 minutes of running, after an extremely large rain storm the day before, there was literally zero water left coming from the inlet pipe into my sump pit. So, for the first 6 weeks of use, I had been extremely pleased with this purchase.

However, about a week ago we had one of the biggest down pours that I could remember. It was the middle of the night, and I was woken up by the lighting, and I decided to run downstairs to check on a small foundation crack leak that we are dealing with currently. Its only an issue on very heavy rains, which this was, so I went down to see if I had any problems to deal with, and I actually did have a small puddle forming from this crack. However, I saw the that the sump pump was working, so I was happy about that. While I was toweling up the water from the crack I noticed that I didn't hear any water running through the sump pump discharge lines, which was how I could tell the pump was running, since the pump is so quiet. I went over to my sump pit and I saw through the check valve that there was no pumping going on, and also the sump pit was starting to fill with water. The pump was definitely powered up and "running", however it was not pumping any water.

After a quick panic, I realized I had a small backup pump from Walmart, that I hooked up as quickly as I could, before the sump pit overflowed. Thank god I had this pump, or I would have had a basement full of water very quickly. Always have a backup!!

After getting the backup pump running, I turned my attention back to the Liberty Pump. I turned it over and saw the problem immediately. The impeller had completely come lose and was just rolling around inside the cavity between the pump housing and the bottom plastic plate. After popping the bottom plate off to get a better look, it appears that the impeller just completely came off the shaft that connects it to the motor. I dont know if a nut came off, and then the impeller got looser and looser until completely falling off or what. But I had only used this pump for 6 weeks at most, and this should not have happened.

I am extremely lucky I just happened to be downstairs dealing with the foundation crack leak when the sump pump failed, or I would have definitely woken up with a basement full of water, from this Liberty Pump failing. Amazon is replacing this pump free of charge, and I am going to try and stay optimistic that I just got an atypically bad pump from Liberty, since so many others have posted such great reviews on this pump. I will try to update this review after a few months of using the replacement, hopefully with no problems.

Lesson learned: ALWAYS HAVE A BACKUP!!

I had a flotec 3/4 hp pump for about 7 years. It worked fine but it was quite loud. I would know upstairs that the pump was turning on.

I investigated several pumps at Home Depot, Menards and online. Most pumps at HD and Menards were made in China but I think there were a couple made in USA. The made in USA pump was being sold in several different brand names - but they appeared to come from same manufacturer. Often they had a tethered switch - which is rather inconvenient to set up. Also, I checked the reviews of those pumps and they had one common problem - switch failure after a few years!

Finally, this liberty pump. Made in USA and outer appearance does make it look superior to others - including the other unit made in usa (forgot the name brands).

We have had constant rains for past week in Wiscosin and this pump is more than sufficient for my need. 3/4 hp was over kill. I suspect for most people, as a sump pump, 1/4 hp is more than sufficient (unless you have a special situation/problem).

This liberty pump is very quiet. You would barely notice that it is working. It has a built in float and magnetic switch, which makes set up very convenient.

You should buy a check valve. I bought Zoeller but I think Campbell Mfg Quietsump Chk Valve would have been better. Buy a check valve which allows 100% flow through diameter. Cheap ones open only about 45 degrees or so.

If you are seeking to replace a sump pump and cannot afford failure (I have a $150,000 worth finished basement + $25,000 audio equipment), consider this liberty pump. Of course, I have not tested this for longevity. Flotec worked just fine for 7 years but based on the "sound of refinement", I get the feeling this liberty pump would work just fine for another 7+ years. Made in USA is a big plus for me and it outward build quality shows the attention to detail.

And yes, I do have a backup system - I use zoeller water powered backup system.

Btw, the instructions say that you should drill a 1/8th inch hole near the outlet - to avoid air lock. I did so but it was splashing water. Therefore, I replaced it with a connection without the 1/8 inch drill hole. The pump works fine. It does have a built in vent hole in the base/body of the pump and you don't need another vent hole. I am using zoeller check valve and I don't have an air lock issue.

The pump is fast and quiet. Because of the vertical float switch it fit into my very small sump pit. I also like how the switch seems to work up and down in a flawless vertical motion unlike others that get hung up on the walls of the pit. I installed it with a check valve that makes it operate more efficiently. Overall very satisfied so far. Liberty makes pumps far superior to what is sold in the big box stores and this even cost me less.

I've had a Liberty pump model 257 for over six years and had no problems to date. I recently purchased another Liberty pump model 257 as a backup. I wish this pump had a longer pump interval otherwise it has been operating great. We have a issue with our basement every Spring where snow melt and rainwater add to a very high water table. This pump runs almost continuously for weeks during the Spring. Great pump for small basin.

Just installed the Liberty 257 sump pump in a 16" diameter sump pit with plenty of room to spare. I love the compact design with unobtrusive vertical float. I had a major concern when, during installation, I discovered I have a 1 1/4 inch discharge pipe, not the required (per instructions) 1 1/2 diameter. I called Liberty technical support twice, and was told each time a 1 1/4 diameter discharge should be fine for this 1/3 HP pump.

All in all, I think the Liberty 257 is just as good, if not better, as the major competitor's green one, mostly because of the ingenious compact magnetic vertical float that the other one doesn't have. In addition, the green one requires a minimum 18 inch diameter pit, whereas the Liberty as small as 11 inches. The build quality is certainly equivalent.

This is a solid, heavy steel case pump. It has a substantial feel to it compared to big box store brands. It has a nice durable finish. My installer was quite impressed with the quality. It operates smoothly and quietly with a lot of power. Made in the US too.
I highly recommend it

I installed this sump pump about a year ago and it has worked efficiently and quietly since then. Installation was not hard, and the pump feels like a heavy-duty piece of machinery. This is the sort of product that you expect will work 15 years without any maintenance or bother, and I'm not close to that yet. However, so far, so good -- and I really appreciate that it was made in the USA.
