Backflow valve installation in Ümraniye is a safeguard that protects basements and ground floors when the street line fills in the rain and surges back into the building. In sites with enclosed car parks in Atakent and Çakmak, the first sign is usually water dripping from the car park ceiling or waste water overflowing from the manhole cover.

Cantley takes calls in Ümraniye 24/7 and starts by inspecting the problem at your address. We follow the building line with a CCTV drain camera to find where the connection meets the main sewer, and only then decide on the valve position together with you. In an office or business block, the basement storage room and floor drains are often the first risk points. In a new residence, it is usually the foot of the car park ramp.

## Drains below street level in Ümraniye

Sites in Atakent and Çakmak connect basement and car park drains to a shared line, so drains below street level are a common sight there. In the five or six storey buildings of Yukarı Dudullu and Tantavi, the basement or the ground floor shop sits at the lowest point. In workshops in Dudullu, heavy use of the floor drain can mean it is the first place to overflow in the rain.

When buildings renewed through urban renewal share the same garden manhole with their older neighbours, you need to work out which building the overflowing water is coming from. Once a backflow valve is fitted, your own line is protected and nothing flows back in, even when the street line is full.

## Frequently asked questions

### If dirty water comes out of the basement drain in the rain in Ümraniye, is a backflow valve essential?

If dirty water rises from the basement drain in the rain, it usually means the street line is pushing back into the building. First the line should be inspected with a camera to confirm that the water is coming from the sewer. Once that is confirmed, a backflow valve stops this reverse flow.

### What should I do if water still comes in during rain even though the building has a backflow valve?

The valve flap may be jammed with sediment, or its seal may be worn. In that case the valve is cleaned, repaired or refitted in the right place. Do not try to remove it yourself.

### Does the floor have to be broken for backflow valve installation?

The floor is not broken when the valve is fitted inside a manhole. If the valve has to go on a buried line in the basement, the work is kept to that spot and the area is cleaned when the job is finished.
