Repair guidance / Saniflo / BR2
The unit starts by itself repeatedly
Describe the interval between starts and whether a toilet or other connected fixture is being used. Repeated short operation differs from a single long run. Give the exact model and connection details; do not alter discharge or non-return fittings as an experiment.
A different pattern: water backs up at a connected fixture
Stop using all fixtures connected to the pump. Identify which fixture backs up first and whether another fixture triggers it. Avoid drain chemicals and do not open a pressurised or contaminated unit to investigate the obstruction.
A fitted appliance behind a furniture door
Describe the visible furniture panel, plinth and surrounding cupboards. A built-in appliance needs its access and connection arrangement checked before removal; do not detach cabinetry or pull the appliance forward to make the enquiry.
Identify this Saniflo model
Copy the complete Saniflo model name from a safely accessible label. Different pumping units serve different connected fixtures; a similar shape does not establish replacement suitability.
Preparing the Keston visit
Keep the Keston address and complete postcode together with the equipment details. Mention whether this enquiry concerns a fitted appliance, an existing pump or a unit below the kitchen sink so the intended work is clear before booking.
Questions for this repair enquiry
What details help with “the unit starts by itself repeatedly”?
Keep the last successful operation separate from the first sign of the problem. For a report of “the unit starts by itself repeatedly”, say what still works and what no longer happens. If the other pattern, “water backs up at a connected fixture”, has also occurred, include its timing as a separate observation. Send these details with the full model and your Keston postcode; they prepare the enquiry without identifying a part in advance.
How does “water backs up at a connected fixture” change the enquiry?
Treat that as additional evidence rather than proof that both symptoms have one cause. Explain whether the two patterns began together or appeared at different times. Include the fitting context — a fitted appliance behind a furniture door — so the assessment can account for safe access as well as the reported behaviour.
