Sultangazi Combi Vacuum Jetting Truck

The Cantley team first inspects the problem at the address and shows you the cause with a camera, then moves on to unclogging the drain. No line is flushed unnecessarily before it is clear which cover to approach from. A drain problem hitting several flats in the main line at the same time is handled with the same method.

In Sultangazi, four- and five-storey apartment blocks built wall to wall are common, and many have had an extra floor or attic floor added later. The shared stack and the building's outlet line, however, have often stayed at their original diameter. Grease from the kitchen and hair and soap residue from the bathroom collect at the bends of these narrow lines, and the blockage is usually felt first on the ground floor or in the basement. When buildings renewed under urban transformation share the same street line with their older neighbours, the new building's clean connection can also be affected by a blockage in the old line.

Bakeries and restaurants on the main street put a grease load on the shared line, so when we inspect the drain of a shop on that street, we use the camera to tell which business the load is coming from. When water comes back up from the basement drain of a small workshop, fitting a backflow valve at the basement outlet after cleaning the line is the lasting fix. On sloping streets, soil washed down by rain must also be taken into account.
