Pendik Backflow Valve Installation
Seeing dirty water rise from a basement floor drain or a shop's drain on a rainy evening is usually the first sign that points to backflow valve installation in Pendik. In dry weather everything looks normal, because the line in the street only fills beyond its capacity during a downpour.
Your building's sewer line carries waste water to the main line by gradient, but once the street line is full, pressure can push back up through the lowest drain in the opposite direction. At Cantley, we first inspect the line on site with a drain camera, show you which drain the backflow is coming from, and then place the valve at the right point. The flap of the backflow valve opens with water coming from the building and closes under pressure from the mains line, sealing the pipe. You can describe your situation to us by phone or by writing on WhatsApp.
Why a backflow valve matters in Pendik's older shop buildings
In Pendik centre, the streets close to the ferry pier and the railway line often have older buildings with shops on the ground floor and flats above. In buildings like these, the basement, the laundry room or the shop's drain can sit below street level, and when the network is under the most strain in the rain, the first water comes out of these points.
A building caretaker will call when the water at the basement entrance dries by morning but leaves a mud mark on the wall. The owner of a shop on the main street will call when foul-smelling water rises in the ground-floor toilet after a downpour. In both cases we first look at where the line is running backwards. The valve is usually fitted on the section of the building line before it joins the network, or inside a manhole. If the work can be done inside the manhole, the floor does not need to be broken.
Frequently asked questions
When is backflow valve installation needed in Pendik?
If dirty water rises from a basement drain, a car park grate or a ground-floor toilet when it rains, you should consider a backflow valve. A building that sits below road level, an older flat above a shop, or frequent pooling of water in the street are also factors that bring it up.
Does the floor need to be broken to install a backflow valve?
In most cases it does not, because if the valve can be fitted inside a manhole or on the basement line, the floor is not broken. Which route is chosen becomes clear once the layout of the line has been examined on site.
Does an installed backflow valve need maintenance?
Yes, it needs to be checked from time to time. If sediment builds up in front of the flap, the valve will not close fully and water can still come in when it rains. After installation, we show you where the valve and its access cover are, and explain when to check for sediment.
