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.
If ordinary use is inconsistent
A few notes of setting, stage and outcome can help. One successful use between faults is useful context, not proof that the problem is resolved.
Before obtaining a component
Ask the team to assess the actual product and proposed work. A web symptom or code from another family is not a reliable order for parts.
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 address
Give the full service postcode and describe the actual fitted access in Blackheath. SE3 is a broad postal reference. This guide does not establish a separate branch, service boundary or agreed attendance.
Discuss the proposed work
Call 0800 037 4915 with the model and sequence of events. Suitable work, charges and a Monday–Thursday appointment are checked for the individual request.
