Sarıyer Manhole Unclogging

At Cantley, we first open the manhole cover and look from above at the water level in the chamber and which pipe the water is coming from. Once we have shared the cause with you, we clear the outlet line with a motorised drain snake and wash the chamber and the connected pipes with high-pressure water jetting. When the job is done, we send the camera into the pipe leaving the manhole and show you on screen that the line is clear. If tree roots or a broken pipe turn up, you can see that on the screen together with us.

In Tarabya and İstinye, some buildings sit very close to sea level and others lean against the hillside. In buildings on the coast the wastewater line has limited fall, so water flows slowly and backflow can appear in the basement during busy periods. In older houses on the slopes, cast iron and clay pipes from different periods have been joined together, so working without a camera means relying on guesswork.

In houses with gardens in Zekeriyaköy and Kilyos, the long line leaving the manhole runs through tree roots, and roots can enter through the joints. In an office block or on an office floor in Maslak, the line serving the staff kitchen and many toilets is affected by heavy use, and in these buildings we do the work at a time that won't disturb the people working there. In Sarıyer flats rented out as student housing or dormitories, if the sink and shower drains are connected to the same line, build-up progresses quickly.
