Empty a full waste tank in minutes — a 12GPM macerator at £109.99

A macerator pump uses spinning blades to chop solid waste into a fine slurry before an impeller pushes it out through a narrower discharge hose. That chopping step is what lets waste travel through a hose a fraction of the width of a standard gravity drain outlet, which is why a macerator empties a tank in minutes rather than the longer time a wide-bore gravity valve takes.

Rated at 12 GPM, it's built to clear a typical caravan or motorhome grey or black tank within a few minutes rather than the longer gravity-drain time of a standard valve.

Macerator pumps typically draw more current than a standard fresh-water pump because of the cutting motor — check the rating plate on this model and fuse the circuit comfortably above the stated draw.

Yes — as a macerator it's designed to chop solids in the waste stream before pushing the mixture through the discharge hose, unlike a plain transfer pump.

Macerator pumps of this type are built for fixed grey or black waste tanks with a pump-out outlet, not cassette toilets, which empty by removing and pouring the cassette directly. Check your tank's outlet fitting against this pump's inlet connection before ordering.

The overcurrent thermal protection cuts power to the motor if it stalls against a blockage, protecting the windings rather than letting the motor overheat.

Check the listed lift and run distance in the specification table — most macerator pumps of this type are rated for several metres of lift and a longer horizontal run, which covers most disposal point layouts.

It's designed to connect to your existing waste outlet with the hose and fittings included, so it can be fitted as a permanent installation or kept as a portable unit depending on your setup.

It runs from a 12V leisure battery supply through an inline fuse, matching standard caravan and motorhome 12V wiring practice.
