Wasteflo WC4C - Bathroom macerator pumps


The Wasteflo WC4C macerator is ideal when transforming any area into a complete bathroom or en-suite.

The slimiline design of the Wasteflo WC4C macerator is designed for installation out of sight behind a stud-partition or other enclosed space and is ideal for use with a back to wall or wall-hung toilet.

An innovative watertight cassette unit enables easy removal, cleaning and maintenance of the working parts without having to remove the WC, cistern or pipework.


  • Macerators are a simple way to pump waste water from a sanitary appliance where there is no local access to a soil pipe
