Kartal Backflow Valve Installation
For backflow valve installation in Kartal, the first job when the team arrives at the address is to check which of the building's drains sit below street level. The basement floor drain, the car park grate or a ground-floor toilet are the first places dirty water will come out once the street line fills up. Then we decide which section of the line the valve should go on.
In Kartal buildings on the flat ground near the coast and on the slopes, heavy rain can fill the street sewer and push foul water back up the building's line. A backflow valve is a part that blocks this route and lets flow go in one direction only: the flap opens as waste water passes out, and pressure coming from the opposite direction seats the flap and shuts the line. At Cantley, we fit this part in the right position for your basement, car park or garden floor.
Why a backflow valve matters on Kartal's sloping streets
In Kartal, older apartment buildings near the coast and houses with gardens on the hillside stand side by side in the same district. On sloping streets such as Yakacık and Soğanlık, the basement or garden floor of a building set into the hillside can sit below street level. When the street line fills, foul water tries to overflow from this lowest drain.
In a detached house with a garden, the toilet or the laundry drain on a garden floor below road level is usually the first to show a sign. In site management complexes, new blocks added during urban renewal and connected to the old street line can put car park grates and basement drains at risk, so the line of each block is assessed separately.
Frequently asked questions
Do I need a backflow valve if water comes up the basement drain in the rain?
Yes. If everything is fine in dry weather but dirty water rises from the basement drain in a downpour, that is the clearest reason to consider a backflow valve. In this case, water from the street line may be flowing back into the building.
Can a backflow valve be fitted to an old building in Kartal?
Yes, a backflow valve can be fitted to an older Kartal building too. The position is chosen based on the last section of the building's line before it reaches the main sewer, inside a manhole, or on the basement line. When the installation is done inside a manhole, the floor does not need to be broken.
My building has a backflow valve but water still comes in when it rains. Why?
The existing valve may not be working: its flap may be jammed with sediment, its seal may be worn, or it may have been fitted at the wrong point. The valve is cleaned, repaired or refitted in the right place. Do not try to do this yourself by going down into the manhole or removing the toilet.
