Toilet macerator · your observations
Identify the box and what already drains into it.
List the connected fixtures and the one last used before behaviour changed. A WC macerator, greywater pump and lifting station have different applications. Keep the installed unit’s complete designation and leave its casing closed.
Connected fixtures identify the application
A WC unit, greywater-only pump and lifting station should not be treated as interchangeable. List the existing fixtures and exact unit. Commercial or multi-fixture work needs an individual scope discussion.
The pump keeps going after its usual cycle
Name the connected fitting last used and whether there is any backing-up waste. Incoming flow, activation and discharge questions depend on the exact unit. Stop connected use for backup; do not open it or add chemicals.
A message, number or symbol appears
Copy every character and preserve letters, zeroes and punctuation. The meaning depends on the exact product. A similar-looking warning on another appliance is not a reliable component diagnosis.
When replacement is being considered
Discuss the existing unit and connections first. Similar appearance, dimensions or a shared badge cannot by themselves establish a compatible replacement.
When the sequence is hard to remember
Start with the last ordinary use you can describe reliably. Keep uncertain details identified as uncertain rather than filling them in with a likely-sounding explanation.
