Inspection & maintenance

Carried out byAppointed third-party maintenance team
  1. Yearly: lift cover and check flow in the channel; look for build-up of fat, wipes or debris.
  2. Clear blockages by rodding or jetting from this chamber – never by hand.
  3. If blockages recur, arrange a CCTV survey of the connected runs.
  4. Record every visit in the log below (date, name, findings, action) with photos.
