Macerators are devices used in plumbing systems to break down and dispose of waste materials. They use a combination of cutting blades and a pump to grind up solid waste and toilet paper into a fine slurry. This slurry can then be pumped through narrow pipes, allowing for more flexible installation of toilets and other sanitary appliances, often in locations where traditional plumbing would be difficult or impossible. Macerators are commonly used in basement bathrooms, loft conversions, and other areas far from the main sewage line. A complete bathroom can be operational in half a day. While the macerator itself is typically concealed behind the toilet, it's important to leave access for servicing the pump and water valves.
