About Little Giant Sump Pumps
Sump pumps manufactured by Little Giant can be installed in sump pits or basins, or used for other dewatering or water transfer applications. They are continuous-duty, submersible type pumps featuring a shaded pole motor with built-in overload protection.
Automatic Little Giant sump pump models include an integral or piggyback type switch of either diaphragm, vertical float or wide angle float type with model-specific “On” and “Off” ranges. Manual models can only operate when plugged directly into an outlet.
“CIM” and “CIA” abbreviations in the Little Giant sump pump model name indicate a “Cast Iron Manual” or “Cast Iron Automatic” pump respectively.
Little Giant 6 (Big John) and 6EN series are by far the most popular and fit most residential applications.
APS-115 and SPBS-12 battery backup systems can be used for flood protection and emergency dewatering applications.

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.
