Saniflo Installation & Repair in London
Macerators put bathrooms where gravity says no, basements, lofts, under stairs.

They're brilliant until they're misunderstood: most “blocked Saniflo” calls are a membrane, a blade jam or an installation that never met the manual.
Saniflo installation & repair in London: what the price includes
- 01All major brands
Saniflo, Grundfos and equivalents, installation, service and repair.
- 02Installed to the manual
Correct fall, venting and pipe sizing, the three things that decide whether a macerator lasts fifteen years or fifteen months.
- 03Repairs and rebuilds
Membranes, micro-switches and blade assemblies on the van for the common units.
- 04Honest advice
Where gravity drainage is feasible, we say so, a macerator you don't need is a service contract you don't want.
- 05Sized to the fixtures it actually serves
A macerator rated for a WC and basin will not cope with a shower and a washing machine as well. Undersizing is why these units get their reputation, the unit is not at fault, the specification was. We size for what will be connected, plus what you might add.
Local conditions we work around
Macerators are everywhere in London because basement conversions and loft en-suites are everywhere, and gravity drainage frequently is not available. Hard water is unkind to them: scale builds on the blades and inside the discharge pipe, narrowing it until the unit strains and the motor eventually burns out. Descaling on a sensible interval is the difference between fifteen years and fifteen months. Where gravity drainage is genuinely feasible we say so, because a macerator you do not need is a maintenance commitment you did not want.
