Explain the permitted toilet waste and paper, and provide a bin for everything else. Clear everyday language helps prevent misuse without requiring users to understand the mechanism.
What the observation means
The exact instructions should follow the unit's manual. Avoid claims that the appliance can handle any flushable product.
A useful next step
Include a clear instruction to stop using the toilet and report poor drainage, unusual running or leaks. Make sure guests know where the alternative facility is. A notice supports proper use; it does not replace maintenance or make an already faulty installation safe.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
