A grinder pump is used when a property is located lower than the main sewer line – known as a ‘high head’ sewage application. If you need to pump uphill, are located in an area with a high water table or connecting by a gravity sewer line is not possible, a grinder pump is the ideal application.
In basements or underground toilets there is not enough slope to allow sewage to flow to the main system. Low lying properties are prone to clogging and require more pressure than a standard sewage pump. However sometimes even buildings on the same level as the sewer line or septic tank may require a grinder pump if the flow of gravity is not fast enough. Waste that flows too slowly can cause a build up resulting in a blockage. In these circumstances a grinder pump is used to pump sewage from a building.
The design of a grinder pump enables it to generate higher pressures than traditional centrifugal designs, allowing it to transport thicker substances over longer distances. A grinder pump is used when:
- Pumping to a pressurised sewer main.
- Waste is pumped a very long distance (750 feet or more)
- Sewage is required to be pumped a vertical distance (minimum of 30 feet)
- Managing solids larger than 2″ in diameter
