A Saniflo or macerator pumps waste where gravity cannot. Most faults come from a blockage, a worn part or a failed motor. Switch the unit off and stop flushing, because running a jammed unit can damage the motor. Then send us the model and the symptoms.
Why homes use a macerator
A toilet drains by gravity only when it sits above the main drain. A basement bathroom or loft en-suite may sit too low or too far from the soil stack. A macerator grinds the waste and pumps it away, since gravity cannot do the job.
That makes bathrooms possible where pipes cannot fall. However, it also adds a motor, a blade and a valve that can fail. Our guide to six common Saniflo faults explains each symptom.
Common faults and first steps
Stop flushing when the unit will not clear. Switch it off at the supply, because running it dry can burn out the motor. Use another toilet if you have one.
A humming unit often has a jammed blade, while a unit that blows a fuse may have a failed motor. A leak at the base can mean a worn seal, so switch off and send a request marked urgent.
What a Saniflo repair costs
Fantastic Services gives £90 to £250 including VAT for a Saniflo repair. PumpMaster shows about £125 plus VAT for a domestic visit, with parts extra. These are guides, not our prices, although they show the usual range.
Fantastic Services says a unit often lasts 10 to 15 years. If a repair nears the price of a new unit, replacing is usually better value. Send a request and ask for both prices, since the age of the unit matters.
Where we cover
We cover Northampton and towns within 30 miles. Local pages cover plumbers in Northampton, plumbers in Towcester and plumbing in Rushden, while you can also see our full list of areas.
If the pipe after the unit is blocked, see blocked drains. Planning a new bathroom? See bathroom fitting, since the layout decides whether you need a macerator.
Saniflo Fault Symptoms: Likely Cause and Urgency
| Symptom | Likely cause | Urgency |
|---|---|---|
| Will not flush or blocked | Blockage in the chamber or outlet pipe, often wipes, sanitary items or limescale | High: stop flushing, because forcing it can overload the motor |
| Blows a fuse or will not start | Electrical fault, failed capacitor or a seized motor | High: isolate the unit and keep it off until checked |
| Hums but does not clear | Jammed or broken blade, or a motor seized on debris | High: running it dry can burn out the motor |
| Leaks from the base | Worn seal, cracked casing or a loose outlet connection | Medium to high: water damage risk |
| Noisy but still working | Worn bearings, limescale on the blade or a hard object in the chamber | Medium: book a check before it fails |

How It Works
Describe the fault
Tell us the model and the symptom. Say if it will not flush, hums, leaks or blows a fuse, because each symptom points to a different part.
Your request is passed on
Your request goes to an engineer, who can get back to you with next steps. Switch the unit off while you wait.
Diagnose the cause
The engineer checks the unit, the valve and the outlet pipe. Ask for repair and replacement prices, since the age of the unit matters.
Repair or replace
The engineer fixes the fault or fits a new unit. Ask what to avoid flushing in future, since wipes cause many faults.
