Adalar Manhole Unclogging

The need for manhole unclogging in Adalar is usually spotted by a wet ring around the edge of the cover or by a smell. When the ground-floor sink backs up, it is not yet clear where along the line the problem lies.

A family returning to the island at the end of summer and finding mud around the garden manhole often wonders what to do. Cantley first secures the area around the cover and checks the water level from above the chamber, then talks through the cause with you. Only after that is the drain cleared with a motorised drain snake and high-pressure water jetting.

Manholes and drain lines in Adalar's old houses

Most buildings on the island are old wooden mansions, stone houses or summer homes that only open in the warmer months. In houses with gardens, wastewater often collects in a single manhole, and that manhole can easily clog with leaves, soil and pine roots. Because of the narrow, hilly streets, we carry our equipment up to the hills of Büyükada or into the inner streets of Heybeliada using lightweight machines.

When a building caretaker notices that the drain in a basement left closed over winter has slowed at the start of spring and lets us know, the first step is to lift the manhole cover and look at the condition of the chamber. In an elderly couple's flat, when guests arrive in early summer, the kitchen and bathroom drains slow down one after another and toilet water comes back up. In this case, checking the whole line with a camera shows the point where the old pipe meets the new connection.

Frequently asked questions

Why do manholes in Adalar's houses with gardens overflow so often?

In houses with gardens, the drain is often connected to a single manhole in the garden. Once leaves or roots build up, water comes out of the cover at the first heavy shower. Even if the manhole is cleaned, the problem returns if roots have entered through the joints, which is why we check the line with a camera.

What should I do first if a manhole overflows?

First keep children and pets away, and do not lean over the cover. Note when the water started and whether it is linked to rain, then call 0212 923 66 85 or message us on WhatsApp.

Does pouring chemical drain opener into a manhole work?

Chemical drain opener usually does not work, because it often cannot fully dissolve the layer of grease and wipes in the manhole. When the mixture reacts with the sediment, steam and a sharp smell can form around the cover, which is a risk for the person using it.
