About Liberty Sump Pumps
Most Liberty sump pump models can be categorized into sump pumps with cast iron and aluminum housing. Aluminum models offer a better heat dissipation than cast iron and come with a plastic base, which, if removed, allows suction down to 1/8". Select cast iron pump series feature a Liberty’s unique “Powder Coated Tough” one-piece housing, which resists corrosion better then similar models from competitors and has a longer estimated life span.
Standard cord options for 115V pumps are 10ft and 25ft, with 35ft and 50ft power cord models also available.
Manual sump pump models are operated in manual mode only by plugging the power cord into the electrical outlet, or in automatic mode by using a compatible external control.
Automatic models feature a wide-angle style float or a vertical magnetic float which regulates the On-Off operation of the pump.

Lead Notification
This product does not meet the new low-lead criteria defined in Safe Drinking Water Act
and cannot be used for potable water applications,
including for drinking and cooking. This product can be used for non-potable water
applications only.
Why don't we show the price?
While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
