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.
Liquid appears outside its normal path
Describe the earliest visible point and the stage when you noticed it. Do not move connected appliances to follow a leak, and stop use where liquid approaches electrical equipment.
When another person noticed it first
Retain their description of the setting and result rather than replacing it with a guessed cause. The original observation can help establish the sequence.
When the model is hard to reach
Existing receipts, manuals or a safely visible label may help identify the product. Do not move a connected appliance just to expose the rating plate.
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 Greenwich address
Give the full service postcode and describe the actual fitted access in Greenwich. SE10 is a broad postal reference. This guide does not establish a separate branch, service boundary or agreed attendance.
