Grundfos Toilet macerator · your observations
The appliance and its connections belong together.
Give the macerator label and the sanitary fittings connected to it. A WC macerator differs from a greywater pump; do not assume every product accepts the same waste.
The unit continues running
Explain which connected fitting was last used and when the behaviour began. Incoming flow, activation or pumping may need assessment. Stop connected use if waste backs up; do not open the casing or add chemicals.
The controls do not respond
Does the panel remain dark, or is it illuminated but unresponsive? Include any recent interruption. Leave electrical housings closed and do not attempt live measurements.
If the symptom has returned
Mention whether previous work was carried out and what changed afterwards, using dates or documents you actually have. A similar symptom does not necessarily share the same cause.
If you are considering a replacement
Discuss the existing connections, fitted space and actual product. Similar dimensions or a shared badge do not prove interchangeability.
The Grundfos reference
Distinguish WC/cutter models from greywater-only pumping products. The exact unit and connected fixtures matter; a family name alone does not establish what the product accepts.
At your Blackheath Royal Standard address
