  4 Questions
Q: 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
by B Crotty from Colorado on July 04, 2016

A: B Crotty,

I would not recommend putting a sump pump in a 5-gallon bucket.

18x22 is a standard basement pit.

How high vertically & how far horizontally are you pumping?
by Jim, Product Expert
Q: is the switch replacable & how much thanks
by Richard G from Michigan on December 03, 2014

A: The switch is replaceable however we do not offer these parts. These can be obtained through the Liberty Pumps WEBSITE. Please refer to them for pricing and availability.
by Jim, Product Expert
Q: 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?
by Scott S from Maine on September 08, 2013

A: There really isn’t an advantage over cast iron or aluminum for you application. My concern would be the iron building up on the float of a model 237 and not allowing it to operate properly. You would need to periodically inspect it and clean it off. The other option if you have the room is to go with a model 233 which has a tether float switch.

by Jim, Product Expert
Q: What kind of warranty do you have on your pumps?
by John from Pennsylvania on July 03, 2012

A: Pump warranties vary from 1 year to 5 years depending on the pump and the manufacturer. That being said, all pumps should last a good 5-7 years or more providing they are installed properly.

Sump Pumps Direct Recommended

Built in the good ol’ U.S.A. the 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... more

The sump pump looked to be built with quality. At first test it performed excellent. I thought the price a bit high but with the free shipping and quality it was worth the buy.
Pros: High Quality, Easy To Use, Exceeded Expectations, Fast

Liberty Pumps 257
Bought this pump to replace a failed pump used in a basement at a rental property. Failed pump was a 3/4 hp motor. The Liberty Pump is only 1/3 hp, the pump is very quite, can hardly hear it run, it pump's great and pumps a high volume of water. Cost was very reasonable. Only down fall is the short cycling due to the float's short distance between on and off cycle but that seems to not be a big deal. I'm am highly satisfied with this purchase. And hope to have long life from the pump.
Pros: Quiet, High Quality, Price, I'd Buy It Again
Cons: None So Far

First Ever Experience With Liberty
The pump I purchased was tested out of the box when received. I filled a 55 gallon barrel with water and cycled the pump. It worked as expected. I measured the on and off points and made notes. I put the pump in inventory for the future, either in my storm sump or a septic lift station. I expect at least a 5 year life span.
Pros: Quiet, Price, Durable
Cons: None So Far

Replacement Pump
With the external vertical switch the pump turns on more often due to the swtch distance. Just installed the pump in the same position as the old pump and now will probably raise the new pump to a higher level in the pit to reduce the frequent cycling. Otherwise a good American pump solid and quite operating.
Pros: Quiet, I'd Buy It Again, Durable, Easy To Use
Cons: None So Far

Excellent Sump Pump
I replaced an older model Liberty Pump. After 15 years, I thought it was time to retire the original pump with a new pump. The pump worked exactly as expected and the vertical float design allowed it to fit into a smaller sump basin. Customer service rep. Aimee was really helpful in determining the right pump size for my application as model number and HP rating was no longer readable on the original pump. I sent her pictures that she shared with internal staff to come up with the right... more
