Sultanbeyli Backflow Valve Installation
If dirty water rises from the basement floor drain when heavy rain falls, backflow valve installation in Sultanbeyli is the solution designed to stop it happening again. When the street line fills up, sewage runs backwards through the building's connection and comes out of the lowest drain below street level. The valve cuts off this reverse flow, but whether it works depends on fitting it at the right point.
At Cantley we start by running a camera through the line to find which drain sits below street level and where the line joins the main sewer. The position and type of valve are chosen from those findings, and the installation is carried out only where it is needed. We also show building management where the valve is and where its access cover sits.
Backflow risk in Sultanbeyli's apartment blocks with floors added on top
In Sultanbeyli, apartment blocks that were first built with a few floors and later had flats added on top are among the building types we come across often. The shared stack often stays at its original diameter while the load grows, so in a downpour the lower floors are the first to be affected. When a building caretaker sees dirty water coming from the basement laundry room drain in the rain, the problem should be looked for across the whole building rather than in a single drain.
In buildings with a bakery, grocer or coffeehouse on the ground floor, and in offices and business centres, the drains join the residential line. If an office owner notices the toilet bowl on the ground floor rising by itself in the rain, that pressure shows the flow is coming back from the opposite direction. In buildings like these we run the camera through every drain on the line and share with management which one connects to which line.
Frequently asked questions
Which buildings in Sultanbeyli need a backflow valve?
A backflow valve is needed in buildings where some of the drains sit below street level, for example buildings with basement or semi-basement flats. Even if these buildings have never flooded before, they can still be at risk of backflow in heavy rain.
Does fitting a backflow valve end flooding in the rain?
A backflow valve that is fitted at the right point and maintained protects the building side while the street line is overflowing. If sediment builds up in front of the flap, the valve may not close fully, so it needs to be checked from time to time.
I already have a backflow valve but water still comes up in the rain. What should I do?
First have the existing valve checked, because even where there is a valve it may be jammed with sediment, have a worn seal or have been fitted at the wrong point. If one of these is found in your building in Sultanbeyli, the valve is cleaned, repaired or refitted in the right place.
