Little Giant Sewage Pumps (Sewer Pumps) are mainly designed to discharge both solid and liquid waste from sewage basins, receptacles and tanks. They are typically installed in the lowest area of the location where waste water and solids removal is needed, such as basements.
All Little Giant Sewage Pumps are fully submersible and are generally divided into automatic models (with float switch) and manually operated models.
Sewage pumps are sized based on the system requirements and pre-existing conditions, such as size of solids, system pressure drop, size and length of discharge pipes, elevation, etc.
Retailers like PexUniverse have the legal right to set their own prices independently, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's "minimum advertised price", the manufacturer does not allow us to show you our price until you take further action, such as placing the item in your shopping cart, or in some cases, proceeding to the final checkout stage. The steps required depend on the details of the manufacturer's minimum advertised price policy. Taking these steps allows PexUniverse to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products.
This won't require you to purchase the product. You can easily remove it from your cart if you decide not to buy it.
We realize that this is an inconvenience and are regularly working to educate manufacturers on how their policies impact our customers.

They have 2" discharge outlet (3" optionally), can handle large solids of up to 2" in diameter, have 4/10 horse power rating and are best suited for medium to low pressure drop applications.
Little Giant 9S-CIA sewage pumps:
9S-CIA series Little Giant sewage pumps (i.e. sku# 509500) are automatic and come with a float switch to shut off the pump when the water level reaches a certain point. Similar to 9S-CIM series, they can handle large solids of up to 2" in diameter, have 2" or 3" discharge size and are best suited for medium to low pressure drops.
Little Giant 10S-CIM sewage pumps:
10S-CIM series Little Giant sewage pumps, such as sku#'s 511400 and 511420 are designed for applications with higher pressure drops and higher flow requirements. 10S-CIM models are manually operated sewage pumps.
Little Giant 10S-CIA sewage pumps:
Fully automatic, the 10S-CIA series Little Giant sewage pumps come with a float switch, which activates/deactivates the sewage pump once a certain waste water level is reached. These are designed to handle 2" size solids and are well suited for applications with high pressure drops and high flow requirements.
Little Giant 10SH-CIM sewage pump:
This model is specifically designed for use in high head applications and has a head rating (shutoff pressure) which is 40% greater than the regular 10S models. This model is manually operated and can handle 2" size solids.
