Silivri Backflow Valve Installation
For backflow valve installation in Silivri, the first job when the team arrives is to check which of the building's drains sit below street level. When the street line fills and overflows, water can come up through the lowest drain in the building, so this check decides where the valve goes. It matters most in buildings with a basement, a car park, a ground-floor shop or a garden-level flat.
If water rises from a basement drain or a ground-floor toilet in the rain, you first need to see where the backflow is coming from. That is why the team follows the line with a camera, finds the main manhole and the point where your line connects to it, and picks a spot for the valve where it can be serviced. After installation, water is run through the line and the flap is tested to confirm it closes against the flow in the opposite direction.
How do older buildings and newer housing complexes strain the line in Silivri?
In central Silivri, older blocks lived in all year round stand next to housing complexes built in recent years. In older buildings, grease built up in kitchen lines and a narrowed shared stack can disrupt the flow, while in newer complexes, material that slipped into the pipe during construction can do the same. In both cases, when the street line fills up, water can come back up through the same drain.
In the summer housing complexes around Selimpaşa and Gümüşyaka, the shared line may not have been built for summer, when every home is occupied at once. If site management reports water coming up through the basement car park grate in the rain, the team first inspects the shared line by camera and decides with management where the valve should be fitted. If dirty water rises from a low ground-floor drain in a small workshop in Silivri, the cause is most often found in the building's own line. In inland areas such as Değirmenköy, the line is long, so roots and sludge can build up.
Frequently asked questions
Does a building with a basement in Silivri need a backflow valve?
Yes. In buildings with a basement, or a garden level that sits below street level, the lowest drain is lower than the sewer line. Even if you have never seen water come up before, buildings like this can face a risk of backflow in heavy rain.
What should I do if water still comes up in the rain even though I have a backflow valve?
The valve first needs to be cleaned and checked to see whether it is fitted in the right place. Sediment that collects in front of the flap can stop the valve from closing fully. If needed, the valve is repaired or refitted, and the team tests it by running water through the building.
Can I maintain the backflow valve myself?
It is enough to know where the service cover is and to check for sediment from time to time. Trying to take the valve apart or open the line yourself can cause leaks and damage. The team will also tell you when the sediment check should be done.
