Replaced an old one

I ordered this to replace a failed one of the same model. That made fitting it easier. It worked once installed. However, 2 notes. 1. The threads at the mount point were REVERSE of what the old model was. One was inside thread the the other outside. This would prevent the simple reuse of the old hardware so I had to install new hardware. Which brings me to... 2. Despite claiming the adapter was included, it was not. This required an extra trip to the hardware store. Not a really big deal, but something to be aware of when installing. I have another sump with an identical pump. I will order a new one once that dies.

Almost perfect

My house sits on a spring and there is a constant flow of water into the sump pit. Typical life for a sump pump in my house is about a year. Failure happens because of the sheer number of on-off cycles it goes through or the clogging up due to clay accumulating at the intake grates or the discharge pipes. At first glance the ground water looks clear, but there's a LOT of it being pumped (tens of thousands of gallons a day) that eventually the fine clay deposits get big enough. Therefore, every three months I snake the discharge pipes to clean them out. I used to get Rigid brand pumps form the local home supplies store every 12 months or so. My first Liberty pump lasted 15-months and cost about the same to buy as the Rigid. I considered it a success and bought another. It lasted 11-months. I could hear the pump running but no water is being pumped. This was winter and I replaced it with a WAYNE CDU790 pump (about 30% cheaper) and kept the Liberty pump to look at in Summer. The Wayne pump started to show the same symptoms at about 6-months. Inspecting the Liberty pump I took out, I found the intake grates to be completely blocked and cleaned it out with a high pressure hose. This did the trick and it is now back in the job pumping sump water out! I found the Wayne pump grates blocked and cleaned it out the same way. My plan is to switch the pumps every three months when I snake the pipes. The only gripes I have about the Liberty pump are: The float switch only allows about 4" of travel between on and off positions. This gives about 15 seconds of off time between cycles for the pump in my use. So it is constantly running - my guess is around 1000 cycles a day. I hooked up a Superior Pump 92010 Vertical Float Switch which has an adjustable float height to turn off just before the pump's float hits the off mark. This causes the pump's own float switch to be always in the on position and the secondary float controls the on-off cycles. It allows about 10" max travel between cycles and now the pump has 1:38 minutes of rest time between cycles and runs for 3:10 minutes each time. With the published pump specification of 30gpm pump rate at 15' head, this gives me an estimate of almost 30,000 gallons a day !!!! My second gripe is the 1/8" vent hole required on the discharge pipe. When the pump is running and the water level drops below the vent hole, there is a loud spray of water out of the vent hole that can be heard anywhere in the basement. We watch movies and listen to music in the basement and the water noise every 2 minutes or so is quite annoying. The Wayne pump does not require the vent hole and when the Liberty pump fails dies before the Wayne, I might consider getting another Wayne CDU790 just to avoid the noise issue. My application is not typical and ALL the pumps I have tried fail in about a year -- well within the manufacturer's warranty period. Since I literally work them to death, I don't think it is fair to claim warranty. The failures I encounter are due to excessive use. On a regular application (like my old house where the pump ran about 10-20 times a year) the failures might be due to age or contaminants in the water such as corrosion, bearing/seal decay, or stuck float switches. I have no experience to comment on how these will age in a long term application (my guess is that 10+ years might not be unusual) but for just for all-out heavy use, this Liberty pump hold out quite well.

Worked well then died at 4.5 years

Not sure if 4.5 years is worthy of 4 stars but it did work well while it lasted. Considering buying another but might go with another brand instead.

It has really great reviews on Amazon

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 wish the VMF switch could be adjusted.

We recently had an addition added to our house, which required a second sump pit in the new area of the basement and the plumber had installed another similar 250 series Liberty Pump VMF into that pit. Soon after, our old pump in our original pit started to die and I was impressed enough with the performance of the 1/4 hp version of the pump installed in the other location to purchase this for our other pit. These pumps are very (relatively) quiet, clear a cycle in only a matter of seconds and the whole package just looks and feels like a high quality piece of machinery that I can trust. Performance wise, they're great, no complaints. What I remain unsold on is the VMF switch mechanism. On the pro side, the VMF switch means there is only one cord leading to the pump instead of the traditional two with a separate float switch, everything is integral to the pump body. It also means that the switch is much less likely to get caught up on something inside or the side of the pit itself causing a no-pump or continuous-pump situation. However, my big issue with the VMF switch is that if there is no way to adjust the water level required to activate the and personally I feel it activates with too little water in the pit causing more cycles than I would personally have chosen if I could have adjusted the float position myself. You can set the whole pump on something like a brick in the pit so it takes more water before the pump cycles on however you are then in the situation where you will never pump out all of the water from the pit - it can only pump to the bottom of the pump body obviously - leaving you with more standing water. With a regular float you'd just raise the float as much as you want and then the pump would pump all the way to the bottom of the pit. This situation is ideal, in my opinion. It would be a 5 star product easily if the VMF mechanism had some adjustment built in to raise where the float activates, as it stands though I see this as a somewhat annoying drawback.

Well built, extremely quiet!

This sump pump really impressed me. First of all on looks alone this thing stands out as a quality product. You can tell it is very well made in the quality of materials used, it is also quite heavy compared to the first sump I purchased (which died after 1 year of use). The instruction manual is pretty sparse, and there is a good reason for that, its extremely easy to setup and essentially maintenance free. Other than having to trim the ABS pipe shorter (as the discharge on this unit sits higher) it was a very painless install. After using this sump pump for the spring thaw I am very pleased with how it operated, its is so quiet compared to my previous pump that we can barely tell when its running, our previous pump made a terrible racket to the point that we had to shut the door to the utility room or else it would wake our kids up sometimes. The only thing I wish I could change is the float sensor, I have a small sump pit and this pump is so powerful it drains it within seconds, making for a short cycle time. I would prefer letting it leave a bit more water in the pit before pumping out, however they do sell a model with a float switch instead so if this ever needs replacing I will go that route so I can control the water depth.

3.5 years, still flawless

This pump has been installed and operational without skipping a beat for 3 and a half years now. Runs very quietly, very reliably, and feels very well built. Honestly, the exterior finish looks nicer than I'd consider necessary for something that resides in a sump pit, but I can't deny that it does lend an aire of quality. Pairs great with Campbell's "the quiet check valve" for very unobtrusive operation. I agree with others that a means of configuring longer pumping cycle would be nice, but not worth sacrificing any of this pump's other excellent attributes.

A perfect worry-free solution for my cramped sump pit

The first day of the spring thaw and this pump is working like a champ First, a note about customer service: I noticed that my pump was cycling ON for 55 seconds and OFF for about 15 seconds and I wanted to know if the cycle time was OK or if it was too short. I used the Contact Us form on the Liberty Pump site. They responded in 9 minutes which IMHO is truly remarkable customer service on a Good Friday. BTW they said the duty cycle is fine and said "Typically you would want a pump to run for a minute before turning back off." If you have a chance, read the engineering specifications on the Liberty Pumps website, Aside from the build quality I like that they considered "serviceability" and will ship parts within 24 hours. This is a solidly built pump and is definitely built to last. I also like the float on this pump too, it's affixed to the body of the pump so you don't have to worry about it getting hung up on anything. I'm glad I didn't cheap out.

When a piece like this is heavy as it is

Wow.... Fabric, materials is impressive.When a piece like this is heavy as it is, it'S proof of quality. Believe me, as soon you unbox the unit, you'll understand. As of the performance.... it's amazingly quiet. My plumbing is about 20ft linear ( many plumbing elbows and about 10ft above the pump ) and it just throw out the water. >>> 3y warranty >>> 5A I also recommend the check valve probably at the bottom of your screen ( I paid 27$ ): Zoeller 30-0181 1-1/2 Inch Check Valve Works like a charm, easiest thing in the world to install.... ans the quietness ... priceless !! :) Looking for another Liberty pump for my redundant plan ! :)
