The Complete Guide to the New Saniflo Range: Sanisuite, Saniswift, Saniswift Multi & Sanicondens SK6

For over forty years, Saniflo has been the name UK homeowners and installers trust when a bathroom, kitchen or utility room needs to go somewhere conventional drainage can't reach. The new-generation range — the Sanisuite, Saniswift, Saniswift Multi and Sanicondens SK6 — continues that tradition with four units covering everything from a single extra WC to a fully fitted-out basement. This guide explains how each one works, where it shines, and how to plan your installation.

How does a macerator pump work?

A conventional bathroom relies on gravity: waste falls through large-diameter soil pipes to the drains. A macerator changes the rules. When you flush, waste enters the unit and the motor starts automatically, reducing the waste so it can be pumped away under pressure through small-bore pipework — typically just 32 mm in diameter. Because that slim pipe can run vertically, horizontally, under floorboards and through walls, you can put facilities in places a soil stack could never serve: lofts, basements, garages, under the stairs, garden rooms and more.

Grey water pumps work on the same pumping principle but without the macerating stage, because they handle only waste water from appliances — sinks, showers, dishwashers and washing machines — rather than WC waste. Condensate pumps are smaller still, built to move the steady trickle of acidic condensate that condensing boilers and air-conditioning units produce.

Meet the range

Saniflo Sanisuite — the behind-WC macerator

The Sanisuite fits discreetly behind a close-coupled suite or low-level pan and takes waste from the WC and bathroom fittings. It pumps up to 3.5 m vertically and 45 m horizontally (or a combination of both) through 32 mm pipework — or 22 mm using the supplied adapter. It pairs with your choice of sanitaryware with a BS EN33 or EN37 horizontal outlet, requires no routine maintenance, and measures a compact 412 × 273 × 195 mm. Typical projects: under-stairs cloakrooms, loft en-suites, basement WCs, annexes and garden rooms.

Saniflo Saniswift — the grey water pump

The Saniswift handles grey water only — no WC — with four inlets accepting a sink, shower, dishwasher and washing machine. It must be installed with 32 mm pipework, and its compact housing conceals neatly inside a cupboard. That makes it the natural choice for kitchen islands, where waste has to travel up and away from the middle of the room, as well as utility rooms, garages, outbuildings and home bars.

Saniflo Saniswift Multi — the multi-inlet wastewater pump

The Saniswift Multi is the powerhouse of the range. Its rotomoulded tank resists high temperatures and mechanical impact, and six inlets in 40 mm and 110 mm diameters mean it can discharge a toilet, bidet, washbasin and/or shower while also pumping grey water from a kitchen sink, washing machine, dishwasher or bath. The 610 W motor delivers a recommended maximum lifting height of 8 m and horizontal discharge up to 80 m through its 32 mm outlet, and an adjustable outlet elbow tailors the drainage run to your layout. The removable cover and motor keep maintenance simple. Choose it for basement bathrooms, whole-room renovations and any project connecting several fixtures to one unit.

Saniflo Sanicondens SK6 — the condensate pump

The Sanicondens SK6 quietly (45 dB(A)) and automatically removes acidic condensate from condensing boilers, dehumidifiers and air-conditioning units, lifting it up to 4.5 m to reach a suitable drain. It handles PRV output (though not unvented cylinder discharge), mounts on the wall, and arrives ready to fit with a non-return valve, 6 m of flexible discharge pipe and fixings — ideal where a boiler lives in a garage, basement or internal room with no gravity drain nearby.

Planning your installation

A few principles apply across the range. Every unit needs an electrical connection, so factor that into your plans early and use a qualified electrician. Discharge pipework should follow the routes and sizes set out in each product's fitting instructions — you'll find the official data sheet and fitting instructions linked on every product page in our Saniflo collection. Remember that vertical and horizontal pumping figures work as a combination: the further you lift, the less horizontal run is available, so check the datasheet performance curve for your specific layout. And if you're in any doubt about which unit suits your project, ask us — we're happy to talk it through before you buy.

Frequently asked questions

Can I connect a toilet to the Saniswift? No — the Saniswift is for grey water only. For a WC, choose the Sanisuite or the Saniswift Multi.

What size pipework do I need? The Sanisuite, Saniswift and Saniswift Multi all discharge through 32 mm pipework (the Sanisuite can also use 22 mm with its supplied adapter). The Sanicondens SK6 comes with 6 m of flexible discharge pipe in the box.

Do they need much maintenance? The Sanisuite is designed to require no routine maintenance, and the Saniswift Multi's removable cover and motor make any servicing straightforward. All four units are supported by Saniflo's own nationwide engineer network.

What's the guarantee? Every unit in the range carries a two-year Saniflo manufacturer's guarantee.
