People ask whether backflow valve installation in Çatalca is needed most often after seeing dirty water rise from a basement drain in the rain. This sign shows that the street line is pushing back towards the building, and in most cases the answer is a valve that stops the reverse flow, fitted in the right place.

At Cantley, we start by following the building's line with a camera. We talk through with you which drain sits below street level and where the backflow is coming from, and only then decide where the valve goes. We do not install it before the cause is clear, and if the floor has to be broken, we tell you in advance. In Çatalca's buildings with basements, shops and garden floors, this order prevents unnecessary digging.

## Building drain lines and backflow risk in Çatalca

In central Çatalca, low-rise blocks of flats and shops stand side by side, while in the villages there are detached houses with gardens. In village houses, the drain pipe runs a long way under the garden, bends along the route, and sometimes a single line carries the wastewater of several buildings. In the centre, basements and shop entrances that sit below street level are the first places affected when the street line fills during a downpour. As weekend houses and farmhouses become more common, these kinds of lines come up more often.

If dirty water rises from the floor drain in the basement of a small workshop near the market whenever it rains, the problem is often the street line turning back in at the building connection. In a business centre with offices in the basement, the shared drains of several offices are connected to the same line, and even one overflowing drain can spread water as far as the corridor. In places like this, a backflow valve cuts off the line and helps protect both belongings and business continuity. At addresses like these, finding out which drain the line overflows from is the first step in choosing the right position for the valve.

## Frequently asked questions

### Which signs are enough to justify backflow valve installation in Çatalca?

If dirty water rises from a basement drain, a laundry room drain or a car park grate in the rain, that is the clearest reason for a backflow valve. If the ground floor toilet fills up by itself during a downpour, the same line may be taking back pressure.

### Does a backflow valve protect the building from water coming back from the sewer network?

Yes. A backflow valve that is fitted in the right place and kept free of sediment stops water entering through the lowest drain, even when the street line is full. If sediment builds up in front of the flap, the valve cannot close fully, so it needs to be fitted somewhere reachable and checked from time to time.

### Is the ground dug up for backflow valve installation in detached houses in Çatalca?

If the line has an accessible manhole, the valve is installed without digging. If it has to be fitted on a buried line in the basement, the work is kept to that one point and the area is cleaned up afterwards. For lines that run a long way under the garden, the position is chosen after the line has been inspected.
