Bakırköy Backflow Valve Installation
Bakırköy backflow valve installation is one of the most direct fixes for dirty water rising through a basement or ground-floor drain while it is still raining. In Bakırköy this problem often starts when the sewer in the street goes over capacity in a downpour, because the pressure building up in the network looks for the lowest outlet in the building.
Cantley works 24/7 in all 39 districts of Istanbul. For drains that sit below street level in Bakırköy, the first job is to see where the problem is coming from. We inspect the line with a CCTV drain camera, find the risk point and the connection to the sewer network, and talk through with you at the building where the valve should go. We then carry out the installation according to that plan and, once it is finished, run water through your line to check that the flow is clear. We show you where the valve and its access cover are, and explain to building management when to check for sediment.
Where rainwater meets old drain lines in Bakırköy
In the older blocks of Ataköy, sediment that builds up inside the pipes can narrow the passage of the line. In the older villas and houses with gardens in Yeşilköy and Florya, tree roots and clay pipes can quietly narrow the drain line and set the stage for water to escape in the wrong direction.
A kitchen drain in a café or restaurant in the town centre may be connected to the same line as the flats above. If dirty water comes up from that business's drain when it rains, the valve position is chosen so that it does not block the waste from the upper floors. If an elderly couple living in a ground-floor flat in Yeşilköy or Florya see water rise in their toilet on its own during a downpour, the first thing to look at is why the line is running in reverse.
Frequently asked questions
Which buildings in Bakırköy need a backflow valve?
A backflow valve should be considered in buildings with a basement, a semi-basement flat or a garden floor below road level. In these buildings the lowest drain sits below the street line, so it carries a risk of backflow in heavy rain even if it has never flooded before.
Where is a backflow valve fitted, and is the floor broken during installation?
The valve is usually placed on the section of the building's line just before it joins the sewer network. This point can be inside a manhole or on a stretch of line in the basement. When the installation is done inside a manhole, the floor is not broken. If the valve has to go on a buried line, the work is kept limited to that one spot.
What if water still comes in when it rains, even with a backflow valve?
The valve flap may be jammed with sediment, its seal may be worn, or it may have been fitted at the wrong point, so water can still come in during rain. The first step is to see where the valve is and what condition it is in, and then it is cleaned, repaired or repositioned.
