Maltepe Backflow Valve Installation
For backflow valve installation in Maltepe, our team first runs a camera through the building's line as soon as it arrives at the address. This inspection shows which basement, car park or ground-floor drain sits below street level and where the line connects to the sewer. We do not fit a valve without seeing the cause.
In buildings where dirty water rises from the basement drain in the rain, the problem usually comes from the street line filling up and pushing back into the building. At Cantley, we choose the position and type of valve based on this finding, and we do the installation inside the manhole where possible. When the job is done, we show you where the valve is and where its service cover is.
Why drains back up after rain in Maltepe
Old and new buildings stand side by side in Maltepe. In areas close to the coast such as Küçükyalı and Altayçeşme, when a new building's outlet pipe is joined to an old line, a level difference or a reverse slope can be left at the junction. A tenant who had just moved into Altayçeşme called the landlord when water rose from the basement drain during a downpour, and the landlord did not know where the building's line connected.
In mid-rise blocks in Cevizli, İdealtepe and Zümrütevler, kitchen and bathroom drains connect to a shared stack, and the source of an overflow is often grease and sediment built up at the bend of the stack. A camera inspection also shows which flat is connected to which branch, so the tenant and the landlord see the same picture.
Frequently asked questions
My basement flat in Maltepe floods when it rains. Will a backflow valve help?
Yes. If dirty water comes up through the drain and the cause is the street line filling up, a backflow valve is often the right solution. First we confirm with the camera that the backflow comes from the sewer.
I am a tenant. What can I do if my landlord does not want a backflow valve installed?
Start by photographing which drain the water comes from on rainy days, as this gives your landlord something concrete to work with. You can then ask building management, together with your landlord, to have the building's line inspected.
Does a backflow valve need no maintenance after it is installed?
It does need checking, because sediment collecting in front of the flap can stop the valve from closing fully. That is why the valve is fitted somewhere accessible and checked at intervals.
