Zeytinburnu Backflow Valve Installation
If dirty water comes out of the basement drain after rain, the first job when the team arrives for backflow valve installation in Zeytinburnu is to inspect the line with a CCTV drain camera. On the footage we tell whether the problem is at the street connection or inside the building, and the position of the valve is chosen based on that finding.
We talk through the camera footage with you: which drain the backflow starts from and which lines need protecting. The valve is fitted on the basement line or inside the manhole, and when the work is done inside the manhole the floor is not broken. After installation, water is run through the line to test that the flow is clear and that the flap closes against reverse flow.
Basements and newer buildings in Zeytinburnu
In Merkezefendi and Seyitnizam, small workshops operate in the basements of terraced apartment buildings, and the toilets and sinks are used heavily. Fabric dust and thread get into the line through floor drain grates, and when the shared line fills up, these workshops on the lowest floor are the first to see water.
For the building caretaker, the first sign is usually dirty water in the basement floor drain after rain, while for site management the problem points to the shared line. In the newer buildings around Kazlıçeşme and Telsiz, an outlet added to an old street connection can weaken the joint, so we first use the camera to find the point on the line where the backflow occurs.
Frequently asked questions
Which buildings in Zeytinburnu need a backflow valve?
A backflow valve is the most useful solution in buildings with basement, semi-basement or garden-floor flats whose drains sit below street level. The case for one is stronger if water rises in the ground-floor toilet when it rains, or if dirty water comes up through the car park grate.
What should be done if water still comes up in the rain even with a backflow valve?
In that case the flap of the valve may be jammed with sediment, the seal may be worn, or it may have been fitted in the wrong place. We first check how the flap moves and the sediment inside it, replace the seal if it is worn, and reposition the valve if the placement is wrong.
Does a backflow valve need maintenance after it is fitted?
Yes. When sediment builds up in front of the flap, the valve cannot close fully and protection in the rain is reduced. We show you where the valve and its inspection cover are, and we explain to the management how often it should be checked. If sediment is found during a check, the cover is opened and the valve is cleaned.
