Lines that call for the jetter
- Restaurant branch lines lined with set-up fat
- Plaza mains that block every few months
- Building sewers with heavy scale on cast iron walls
- Storm drains and catch basins filled with silt
- Lines cleared by cable that keep coming back
How a jetting job runs
- Locate the cleanout and run a camera to see the problem
- Pick the nozzle: penetrating, rotating or root-cutting
- Jet upstream from the cleanout in controlled passes
- Flush the debris down to the city connection
- Run the camera again and save the video for your file
Margin note: A recorded camera pass after jetting is the best way to show a landlord or insurer that a line was left clean.
Protecting the building
- Fixtures upstream are covered so water does not spray back
- Floor drains and cleanouts are plugged where needed
- We dial the pump down for brittle or thin-walled pipe
- Work areas are cleaned and mats are rinsed before we leave
Preventive jetting schedules
Busy kitchens and older buildings often do better on a schedule than waiting for the next backup. After the first job we look at the video and suggest an interval, whether every quarter or once a year, based on how much build-up we found.
