Saniflo and macerator pump installation in London
A macerator lets you put a toilet somewhere the soil pipe does not reach: a basement, a loft conversion, under the stairs. It works well when it is the only option and badly when it was chosen to avoid a slightly harder job. We fit them, service them and unblock them, and we will tell you which of those two situations you are in.

Worth knowing first
Some of this may save you a callout entirely. We would rather tell you than not.
Three things go in it, and nothing else
Waste, water and toilet paper. Not wipes — including ones sold as flushable — not sanitary products, not cotton buds, not kitchen roll. Nearly every macerator we are called to has been stopped by something on that list.
A macerator is a last resort, not a first choice
Gravity waste to a soil stack has nothing to break, needs no power and makes no noise. If a conventional run is possible at reasonable cost, take it. We will tell you when it is, even though it is the smaller job for us.
It needs power, access and a warm room
A fused spur, a way to get the unit out for servicing, and somewhere that will not freeze. Boxing one in permanently behind tiling is a decision that gets regretted the first time it needs opening.
Descaling is what makes them last
In London’s hard water, scale on the blades and the pressure switch is what finishes most units off. A descale once or twice a year is cheap and roughly doubles the working life.
Common questions
What can I actually flush?
Human waste, water and toilet paper only. Wipes labelled flushable are the single most common cause of failure we see — they do not break down the way paper does.
Why does it keep running or start on its own?
Usually a leaking WC flush valve trickling water into the unit, or a scaled pressure switch. Both are fixable and both waste electricity and life if ignored.
How long do they last?
Well-treated and descaled, a good many years. Fed with wipes, sometimes months. What goes into it matters far more than which make it is.
Can I put a toilet in a loft conversion with one?
Yes, and it is one of the situations they genuinely suit. The pumped waste needs to reach a soil stack and the unit needs power and access, both of which are easier to plan before the room is finished.
