If dirty water rises from the basement drain during rain in Bayrampaşa, the cause is often that the street line fills up and water flows back into the building the wrong way. Backflow valve installation in Bayrampaşa is considered to cut off that route. In terraced buildings built wall to wall, the lower floors are the first to feel every restriction in the floors above.

A backflow valve is a flap that keeps the line running in one direction only: water leaving the building passes through, while water coming from the street pushes the flap onto its seat and closes the line. For example, in the kitchen drain of a café or restaurant on a main street, grease and dough can build up and narrow the line. The lowest drain in the basement then becomes the first place to overflow in the rain. If you have just moved into a ground-floor flat and water rises from the toilet or shower tray when it rains, that can show the line is taking pressure from the wrong direction. So we first inspect the line on site and explain the cause, then move on to the work that is needed.

## How we protect the line in Bayrampaşa's older apartment buildings

In terraced buildings, narrow shared stacks and long horizontal connections add to the load the line carries, as floors are added over time and ground floors are turned into shops. That is why blockages and flooding usually show up on the lowest floor, in the basement or at the connection where the line leaves the building.

Because restaurants, bakeries, barbers and small workshops line the main streets, grease, dough, hair and fabric dust can end up in the drains. So instead of dealing only with the drain that is blocked, we follow the line out to the street with a camera and explain the findings, with the recording, to you and to building management. After that inspection, the backflow valve is fitted at the building outlet or at the connection under the pavement, at a point that stays reachable for maintenance.

## Frequently asked questions

### When is a backflow valve needed in Bayrampaşa?

If dirty water rises from a basement drain, a laundry room drain or a car park grate when it rains, that is the clearest reason for a backflow valve. The risk is higher in basements, semi-basement flats and ground-floor shops whose drains sit below street level. To be sure, the condition of the line needs to be inspected first.

### Is the floor broken up when a backflow valve is installed?

When the valve is installed in a manhole, the floor is not broken up, because the valve is usually fitted at a reachable point inside the manhole. If it has to go on a buried line in the basement, the work is kept to that one spot. When the job is finished, the area is cleaned and water is run through the line to check that it flows freely.

### What should be done if the existing backflow valve is not working?

First we find out why the valve is not working, then it is cleaned, repaired or refitted in the right place. A valve with a flap jammed by sediment, a worn seal or the wrong position can let water back into the building in the rain. We also explain to you and to building management where the maintenance cover is and when the valve should be checked for sediment.
