Arnavutköy Backflow Valve Installation

In a small workshop, the ground-floor drain may work normally in dry weather, yet dirty water can still come up through the same drain after a heavy shower. If a building caretaker has to open the basement door and sweep out water after every rain, the cause may lie in the building's lower drain line. In cases like this, Cantley first inspects the line with a CCTV drain camera, finds where it joins the sewer, and decides where to place the backflow valve based on what the camera shows.

Arnavutköy is a fast-growing district where old village houses stand next to new housing complex blocks, helped by its links to Istanbul Airport. In new complexes, leftover mortar from the construction period can end up in the lines, while older houses often have later additions with too little fall. Both put extra load on the street sewer. This mixed building stock can raise the risk of backflow on rainy days.

In warehouses and workshops around Hadımköy, rainwater coming off large roofs can add a separate load at the point where the building's line meets the street. That is why a backflow valve is the first protection to consider for premises with low drains. In houses with gardens in Taşoluk and Bolluca, outdoor drains can carry soil and gravel in the rain, so the valve should also be placed where it can be reached for maintenance.
