The manufacturer offers different macerators, toilets and wastewater pumps. A shared brand name does not establish identical function or parts.
What the observation means
Similar prefixes can refer to different applications, and an older revision may differ from the current product. A photograph alone may omit important identifiers.
A useful next step
Copy the accessible label and retain the purchase or installation record. Do not select parts or maintenance instructions from the closest-sounding name. The exact unit should guide advice, while service scope and manufacturer authorisation remain separate questions.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
