Ejector pumps can also be installed if the homeowner feels that gravity is not sufficient to remove wastewater from their house.Ĭompared to other solid and liquid waste pumping systems, sewer ejector pumps are relatively efficient. Homes that are located at lower elevations than the primary sewer lines or have washrooms in the basement of the property have no other option than installing a sewer ejector pump. Perhaps the main benefit that a homeowner enjoys from a sewer ejector pump is the vast level of flexibility it offers. Unlike the submersible and self-priming ejector pumps, vertical pumps are suitable for less regular use. The larger part of the pump is not immersed in the wastewater and thus requires frequent lubrication. These systems come with a motor that rests on a plate and a pump shaft along with a discharge pipe that is both immersed inside the pit. While vertical ejector pumps have been largely out-fashioned by the aforementioned two ejector pump styles, they are long-lasting and they are mostly found in older homes. This is perhaps the oldest technology of sewer ejector pumps. These pumps are designed for shallower pits. Instead of being immersed inside the pit, they are installed atop it and filled with water, hence the name “self-priming.” Compared to submersible pumps, self-priming sewage ejector pumps are easier to uninstall for service maintenance and cleaning. Self-priming sewer ejector pumps are used where there is no adequate headroom inside the sump basin. Submersible pumps come in two types: single-seal design and double-seal design, with the latter being a bit more robust for a system that kicks on throughout the day, without “straining.” Some submersible pumps feature a grinding mechanism to help reduce the size of the solid materials further. They are the most prevalent types of pumps available. However, irrespective of the vast variety of these pumping systems, they are classified into three main groups, including submersible pumps, self-priming pumps, and vertical pumps.Īs the name suggests, these types of sewage ejector pumps are completely submerged inside a sump basin. There are different types of sewage ejector pumps based on style, and manufacturers are adopting different designs and materials to develop them.
