What is a sewage pump unit?
Sewage pump units are compact pump systems that collect wastewater from plumbing fixtures — such as toilets, showers, washbasins, and washing machines — located below the sewer line or where gravity drainage is not possible, and discharge it under pressure into the sewer. They are particularly useful in basement bathrooms, retrofitted toilets, wet rooms in parking garages and storage areas, and renovation projects.
Category contents
- Macerating (blade-type) WC pump units: Shred toilet waste and convey it through small-diameter pipework.
- Greywater pump units: For wastewater without solids, such as from showers, washbasins, and washing machines.
- Tank-type pump stations: Collect wastewater in a tank and automatically pump it out when the level rises.
The category includes models from Wilo, Grundfos, Sumak, and Leo.
Selection criteria
First, identify the fixtures to be connected: washbasin and shower only, or a toilet as well? If a toilet is to be connected, a macerating model approved for WC use is required. Next, calculate the discharge height and horizontal distance to the sewer; the head and flow rate values in the product specifications must cover this distance. The number of inlets and their positions also vary by model.
Installation and use
A check valve must be installed in the discharge line, which should be routed to the sewer via the shortest and least-elbowed path possible. The unit's ventilation connection must be made in accordance with the manufacturer's instructions. Wet wipes, sanitary pads, grease, and construction debris can damage the unit and must not be flushed. The electrical connection must be made from a circuit protected by a residual current device (RCD).
Frequently asked questions
What unit is needed to install a toilet in a basement?
A macerating WC pump unit suitable for toilet waste must be selected.
Is a macerator needed for a shower and washbasin?
No; a greywater pump unit designed for grey water is sufficient.
Does the unit make noise?
It produces some noise during operation; it runs only briefly while water is being discharged.
What happens if the power goes out?
The unit will not operate; the connected fixtures must not be used during a power outage.
How is it maintained?
The tank and blades should be inspected and limescale removed at the intervals recommended by the manufacturer.
What do you recommend for higher flow rates?
For building- and facility-scale wastewater needs, you can browse sewage submersible pumps.
