If you are considering adding a new shower or hand basin to your house or apartment, a greywater pump could be the ideal solution to ensure optimal wastewater removal. Let’s explore what a greywater pump is, how it works, and how to choose the right model for your needs.
What is a greywater pump?
A greywater pump is a sanitary device designed to assist in the removal of wastewater when it cannot drain naturally due to a height difference with the sewer system or the main drainage network. This equipment is particularly useful in bathrooms located in basements or below the drainage network. It is typically installed on the floor, behind a partition, or within a cabinet.
How does a greywater pump work?
The operation of a greywater pump is relatively simple but essential for managing wastewater. When a sufficient amount of water is collected in the pump's tank, a float automatically activates the pumping mechanism. The device then draws in and propels the loaded water toward the drainage network.
Pumps can be equipped with different types of motors depending on the capacity and power needed to lift water to a sufficient height.
Choosing the right lifting pump for your bathroom depends on several factors. Here are the main criteria to consider when selecting from all available products:
- The type of water to be removed: If you only plan to evacuate water from the shower or sink, a pump for clear water will suffice.
- The number of sanitary fixtures to connect: Different models of greywater pumps offer varying numbers of inlets. It’s important to carefully consider the equipment you want to install in your water room to choose the right product.
- The height and length of lift: It’s important to know the height to which the water will need to be propelled to reach the main drainage network, depending on the location of your room. This is called the lift height, a crucial piece of information when selecting your pump. Similarly, you need to consider the distance the wastewater must travel to reach the main drainage of your home.
We recommend consulting a plumber for your project, as they can help you choose the right product based on their experience, manage the delivery and connection of your device for a safe and durable installation.
In summary, a well-chosen greywater pump ensures the proper functioning of your bathroom, whether for draining wastewater from the shower, sink, or basin. Don’t hesitate to compare models based on their performance and consider the installation and maintenance needed to optimize the durability of your setup in your space.
