Saniflo FAQs
How much does Saniflo installation cost in London?
Labour only (unit supplied separately): £180–£350. Supply and fit (we supply the unit): £420–£1,100. The range reflects model complexity and pipework required.
What is a Saniflo and how does it work?
A Saniflo is a macerator unit — it grinds waste and pumps it through a small 22–32mm pipe to the nearest soil stack. This allows a toilet to be installed anywhere without breaking up floors or digging drains. Common in London basement conversions, loft rooms, and extensions.
What can I flush down a Saniflo toilet?
Human waste and toilet paper only. Do not flush: wet wipes (even 'flushable'), cotton pads, sanitary products, dental floss, or paper towels. Blockages cost £85–£150 to clear.
Why is my Saniflo humming but not pumping?
Almost always a seized impeller or macerator blade — caused by limescale build-up (a major issue in London's 290mg/l hard water) or a foreign object. Try switching off for 20 minutes then restarting. If the hum continues, call us — descaling costs £85–£120, blade replacement £120–£180.
How often does a Saniflo need servicing?
Annual descaling recommended, twice yearly in London's hard water area. Annual professional service (£85–£120) includes descaling, seal inspection, and pressure test. Serviced units last 10–15 years vs 4–7 years unserviced.
Can a Saniflo be installed in a basement in London?
Yes — basement installation is the most common use case. The Saniplus and Sanicubic 2 can pump up to 5–9m vertically. We handle all basement Saniflo installations across London.
