Review Posted 04/15/2019
Built in the U.S.A., this Liberty model 257 is a well-known name among plumbers and is a superior pump for the money. This cast iron pump is very efficient with 1/2 the running and starting amps of most other 1/3HP pumps in the same league and with a pumping capacity of 2700GPH at a 5-foot lift and the magnetically operated vertical float switch, this pump is one mean sucker! The 257 will handle any light duty applications with ease.

Unlike many other pumps out there, this pump features a 16-gauge quick-disconnect 10-foot power cord for easy replacement if necessary and upper & lower ball bearings that allow for a smoother and cooler operating environment which translates to a longer motor life.

Coupled with a 3-year warranty, this pump gets our recommendation.

An Experienced Mechanical Engineer's Review
By Richard T, Registered Professional Engineer, Illinois 
Illinois
Purchased 05/02/2024 | 
Review Posted 05/24/2024 
Unique design features: It has an inverted bell jar design for the body casting. In other words, there is no top motor seal to leak and fail. Compared to competitors, it has one less gasket point of failure. Also, it has a magnetic induction float switch. Typical float switches has mechanical linkage seals which are notorious for gasket fatigue. In other words, this Liberty pump switch design has another feature...one more....less rubber seal to fail. For durability and service life, my current sump pump is now 15 years old in my own personal field testing and is still running strong. And since I have a high local water table, my sump pump runs frequently. Reliability is a key issue for me. Recently, I just pulled the pump for inspection, the epoxy coating laid over the cast iron body still looks great. No significant corrosion despite being submerged all these years. Further, all the stainless steel pump assembly fasteners and trim still appear shiny.

Best Practices. Keep a spare. I keep a spare pump on my shelf inventory at home for back-up plus all the necessary plumbing discharge fittings. My insurance claims experience tells me pumps can often fail late on a Sunday evening after the big box stores have already closed. Second, after big storms, next day, there is a purchasing run on available shelf sump pump inventory at Menards or Home Depot or Lowes. The point being, morning after a big storm, everyone then rushes out for a sump pump replacement and the store shelves get quickly picked clean of inventory. Third, sump pumps are a commodity item wherein one gets exactly what you pay for and the big box retailers only seem to stock the lower quality sump pumps for consumer price point. Fourth, avoid tethered float switches. Tethered float switch often get tangled up in the sump pit causing malfunction. Further, tethered float switches experience cable wire fatigue failure with age and movement cycles at or near the flexible attachment pivot point. Fifth, high water alarm devices in or near the sump pit are a good idea. Mine has saved me a mess a time or two in the past when my primary pump was struggling to keep up with a radical storm inflow which gave me additional time to drop in a temporary second discharge pump for added capacity. Sixth, recently, I added cam lock and groove fitting hardware set-up for rapid sump pump replacement (with all the attached plumbing fittings pre-configured).

This is my second one. I use it to help drain standing water from my back yard. So, it runs a lot when it rains. First one lasted for about ten years. Very reliable.

This pump requires a 10" diameter basin, but what about depth? Could I use it in a 5 gallon bucket that has an 11 inch diameter, and is 14 inches deep? My window well space is too small for a 22" deep sump basin

Considering making the Liberty model 257 my primary sump pump and then making our existing Zoeller an emergency backup. We have a lot of iron in our water. Would the aluminum model 237 be better or worse for high iron content?
