Expert Saniflo Repair Specialists in London

This is the most common question we get asked every day. A Saniflo will last many years if looked after properly from new despite what people say. Follow the instructions in the Saniflo handbook. Descale 2–3 times a year in hard water areas, or once a year with a salt-based softener. Avoid flushing foreign objects. Install the waste outlet pipe to pump downhill to reduce motor wear. We can remove foreign objects quickly if needed.

If the Sanicompact buzzes but doesn’t flush, the blade may be jammed with a foreign object. If pressing the button fills the bowl with water but it doesn’t drain, the U-bend may be blocked. Both issues are easily fixed by us.

If your Sanicompact activates regularly day and night, it could be due to a leaking non-return valve. Limescale or a foreign object can hold the valve open. Descaling or replacing the valve will solve it.

If your Sanicompact has an old white single button, the air button may be worn, the air pipe may be loose, or the microswitch might be faulty. We can replace these components to restore functionality.

Check that the Saniflo has power and is switched on. Common causes of non-activation include a faulty membrane clogged with limescale, a defective microswitch, or a dead motor. Sometimes the toilet may be blocked and the macerator is not at fault. We’ll identify the exact cause.

The capacitor may be faulty, especially if the unit is pumping vertically. If not, the motor may be worn out. We carry spare capacitors and can often fix this in one visit.

Kitchen waste pumps like the Sanivite often get clogged by grease, fat, and coffee grounds. Once blocked, descaler won’t help — manual cleaning is required, and we can do that for you.

Possible causes include a blocked U-bend, stiff or leaking membrane, or a faulty microswitch. A leaking membrane may need replacing, as small pinholes are hard to detect. We can reseal the unit and replace the membrane to resolve this.

If the Sanishower has power, the fault may be a membrane, microswitch, or capacitor. We carry all of these parts. If the motor is faulty, a replacement Sanishower will be required.

This could be due to incorrect macerator installation or a dirty chamber. The toilet outlet should be level or above the macerator inlet. If it’s too low, water can run back. Regular descaling is essential. Saniflo Descaler.

If your macerator is vibrating or shaking around whilst in operation and not pumping the water away, it is likely due to a foreign object caught on the macerator blade. We can strip down the machine and fix this problem for you.

This is likely due to a faulty membrane, switch, or both. It may also be caused by a dripping tap, shower, or bidet, or a leaking appliance. Overflowing cisterns or expansion valves dripping into the Macerator are also possible culprits. We can fix this for you.

Try descaling your machine with Saniflo descaler. If the odour persists, it likely needs a manual strip-down and clean. We can do this for you and recommend regular descaling afterwards.

If the toilet is blocked, avoid flushing twice. It may be a simple U-bend blockage. If the machine is hot and unresponsive, the blade may be jammed. We can strip it down and repair it.

This could be due to a shrunken outlet pipe or the machine being overwhelmed by water due to a faulty switch or worn motor. We can replace the switch and membrane or advise if a new unit is needed.

Check the fuse, power supply, and that the machine is not switched off or in thermal cut-off mode. If it still doesn’t activate after cooling, the motor might be jammed. We can investigate and fix this.

This usually indicates a faulty internal connection or water ingress in the motor. We’ll inspect it to determine if a repair is possible before recommending a new unit.

Excess soap or bleach causes foaming. Dilute the contents and reduce cleaning product use in future. Use minimal toilet cleaner and descale regularly.

If multiple fixtures are blocked, the Macerator may be connected to all of them. Avoid using them until we investigate to prevent flooding. We’ll remove the water and repair the issue.

Only Saniflo Descaler has the correct ingredients to remove limescale. Bleach and toilet cleaners won’t work and can damage the motor. Always use a recommended descaler. Saniflo Descaler Instructions.
