The FP400B is a versatile macerator that handles a full bathroom — WC, basin, shower, and bidet — with the added benefit of a top outlet alongside its standard side outlet. This extra flexibility makes it especially useful for retrofit projects, where connecting directly into an existing soil stack can simplify installation. With a powerful 400W motor, multiple inlets, quiet operation, and tool-free servicing, the FP400B combines strong performance with installer-friendly design for reliable bathroom specification.
