Q: I have an engineer's drain field I use an affluent pump to pump my gray water to a drain field up hill about 15 ft at a distance of approximately 80 ft seem to be going thru a pump every 3 years tried them all from Zoeller to the box store brands same result 2-3 years what is the suggestion for my application
by Steven Trammell from Michigan on July 04, 2016

A: Steven,

What size piping are you using?
by Jim, Product Expert

Q: Hi Jim-
I have a 1 1/2 inch discharge line - will this unit, with a 2" discharge port, work with that line? Thanks.
Bob

by Bob from Texas on March 19, 2016

A: As long as you are not pumping any solids that may be larger than 1-1/2" reaching that pump, you should be fine. That said, it's always best to maintain the discharge port diameter on your discharge hose or piping, especially if you are dealing with high heads and long pumping distances.
Are you replacing a sewage pump or a sump pump or another type of pump?
If you have any other questions, please let me know.
by Jim, Product Expert

Q: How many watts?

Is this pump use regular plug?
Same plug, just like model of Liberty Pumps 257(I have this model)?

If this pump keeps pumping for 3-6 hours, will it be OK?

by Chuck from New York on July 15, 2014

A: The Liberty LE51A is rated at 120V with a standard AC plug just like the 257. The watt ratings are 1140 running watts and 2700 starting amps.
These pumps are rated to run for 8 hrs. continuous fully submerged, with at least an hour off in between.
by Jim, Product Expert

Q: Hi Jim - can this pump be used as a sump pump?

Liberty Pumps LE51A - 1/2 HP Cast Iron Sewage Pump (2") w/ Piggyback Tether Float

Also thinking of emergency use to dewater a flooded backyard.

Thanks!

by Brian from New York on August 23, 2012

A: Sure! Because of their higher capacity and small solid handling capability, sewage pumps are a common choice for outdoor applications. Just be sure to keep the electrical connections well protected and if its a permanent installation, please take proper steps to protect the pump and discharge pipe from freezing.

Sump Pumps Direct Recommended

This is a great sewage pump for light commercial duty applications and residential applications and earns our "Better" recommendation. This pump has a heavy-duty epoxy-coated cast iron housing making it more corrosion-resistant for extended pump life.

Another bonus is the 10' quick disconnect power cord which gives you the ability to easily replace the cord without breaking the seals.

Let's face it, you want to change out your sewage pump as infrequently as possible. It's... more

Liberty Pump Keeps My Vacation Home Working
I installed the Liberty Pump in an existing home built 3 foot diameter. 6 foot deep, brick lined septic tank. I built a PVC pipe framework to stand the pump about 3 feet from the bottom. The outlet of the pump is connected to a 220 foot length of horizontal PVC pipe to the main sewer. There is a 2 inch check valve and ball valve in a horizontal position about 6 feet from the pump. Two 90 degree ells and two 45 degree ells were used in the hookup. I was concerned about enough pump output... more

Unbelieveable!!!!!
At the recommendation of a friend of mine who is a master plumber, I purchased this pump. For the last two months, I have had at least 1-2 inches of standing water in my basement. I had an wet basement expert come by and quoted me $30K to solve my problem. A much lesser quote to install a pump that only did 3600GPH, that was going to cost over $1000. With some minor instructions from my plumber friend (I have zero experience with plumbing), I installed this pump and watched the water in my... more

Liberty Pump = Long Life
Pulled a Liberty pump that was installed outdoors in my yard to mitigate water. Installed in Nov 2005, died exactly 8 years to the month later....designed to run no more than 8hrs at a time - but there were MANY times it ran for days on end! Because the float and AC are hard-wired to a NEMA box - Liberty's design made it easy on me with a removable power cord - didn't even have to open the NEMA box to replace the pump! Took no time at all and I hope to get another 8 years out of the new one -... more

Receiving Dock Constantly Flooding
Every Spring when the rain comes down hardest, our receiving dock flooded and the pump we had installed wasn't keeping up at all with the amount of water that went into the bay. I recently purchased this pump to replace the old one and haven't had any problems with flooding or the pump. So far it has proven to be a great investment and I feel as though I definitely got a reliable pump. The old pump was an effluent pump and this one is a sewage pump. This one prevents small things clogging the... more

Happy Customer
Very happy with pump. Works great. Pumps poo with the best of them. The only issue I had was when I picked it up in the box after delivery I took two steps and one of the handles ripped and I dropped the heavy sucker right on my new hardwood flooring. Put a nice quarter size hole in my floor. The little woman is not a happy camper. I should of never trusted the handles. Other than that I'm happy with your company and will definitely buy from you again.

Home Owner
Brought this pump after doing research on all sewage pumps. This pump is backed by a 3 yr war. and is made very good and made in USA. Float switch plug on pump was smashed upon arrival, tried to fix it but didn't work. I called Liberty Pumps and they sent me out another one at no cost. Hooked it in and Perfect. Liberty Pumps back their products and I'm very pleased with the customer service. 5 starts. This pump was also very easy to install.

Extremely Pleased With Liberty Le51a + Sump Pumps Direct
My Liberty 1/2 HP LE51A replaces a Water Ace 3/4 HP unit that was purchased at Lowe's, and less than 5 years old. The Water Ace unit went bad for whatever reasons...Made in China.

After much online research, it became obvious to me that the correct purchase was the Liberty LE51A unit from Sump Pumps Direct. I ordered it online...It was delivered and sitting on my doorstep the following day.

Installation was VERY straightforward...I installed the new pump with a new 2" pipe and I... more

Had an old pump running an entire basement. Kitchen, bathroom, and washer machine with continuous troubles of overflows. Whether it was shower water or waste. All resolved with my new easy to install Liberty Pump. No fear or worries anymore. Highly recommended.

Heavy Duty Pump, Crazy Fast Shipping
First off, I have to confirm all the other reviews regarding how fast Sump Pump Direct ships their product. I ordered this pump on a Tuesday at noon. The next day (Wed), the pump was at my front door. As far as the pump goes, all I can say is that this thing is a beast. The pump I pulled out weighed in at around 15lbs at best. This thing is built like a tank and weighs in at around 45lbs. Easy to install, very quiet, and drains my sump pit in a matter of seconds. No doubt that I made the right... more

"As I said in my product review, I ordered this pump on a Tuesday at noon. It was on my doorstep the following morning. Doesn't get any better or faster than that. Loved all the reviews on the website, both those of average homeowners and also of installation pro's. Absolutely no doubt who I will be buying future sump pumps from."
