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.
A sound has changed
Explain whether the sound starts immediately or at a later stage, using words such as buzz, scrape, tap or rattle. Burning, smoke or uncontrolled movement mean stopping use, not making a demonstration.
Where several functions are involved
Separate the affected function from those that still respond. Keep each observation in its own sentence rather than combining them into a component diagnosis.
When the last use followed an interruption
State the interruption and what happened next, without treating the timing as proof. The model and ordinary operating sequence still matter.
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 Lee address
Give the full service postcode and describe the actual fitted access in Lee. SE12 is a broad postal reference. This guide does not establish a separate branch, service boundary or agreed attendance.
