How Sewage Ejector Pumps Work

Occasionally, a toilet or even a sink needs to be installed below the nearest sewer or septic line, and the waste from the drain must be lifted to the level of the main drain with a sewage ejector pump.

A grinder pump or sewage ejector pump solves this problem and is used when wastewater cannot flow to its destination. PDM is an expert in sewage ejector pump repair, replacement and installation for residential and commercial service.

New Sewage Ejector Installation.

Sewage Ejector PitPDM installed some of the first submersible wastewater pumps in the mid-1950s. We’ve seen and done it all.

Class. There are two classes of submersibles sewage ejector pump, the smaller pump is used in home and light commercial, and larger pumps for large commercial buildings and municipal wastewater systems.

Size. The farther the distance the waste must be lifted, the more powerful the pump must be to do the job. A whole-house system must be larger and more powerful than one that services only one toilet. Residential sewage ejectors normally handle up to 2-inch spherical solids and range from 1/3 to 2 horsepower and are available in two types, non-clogs and grinders.

3 ways to size a sewage pump based on peak flow:

  1. The Fixture unit calculation estimates usage demands of a typical plumbing fixture(s). This method is suitable for residential and small commercial applications.

  2. The Larger Capacity System Chart takes fixture frequency of use into consideration. This method is appropriate for motels, apartment complexes, and large office buildings.

  3. The Population method is used when designing large-scale municipal sewage systems.

Types: Non-Clog And Grinder.

Non-clogs pump high volumes and can handle solids from 2 inches thru 4 inches and are used both in residential and municipal lift stations.

Grinder pumps grind solids instead of passing them. They are sized only for residential or small commercial locations, often pumping to a pressure sewer system but also in gravity sewers with high vertical lifts or long horizontal runs.

Ejector pumps can be installed in wet pits or sewage basins and typically sits in a hole cut through the concrete slab floor. By installing the ejector beneath the floor, the fixture need only be raised minimally to accommodate the flange and waste pipe.
