Beyoğlu Backflow Valve Installation

If you own the property, you first need to work out whether the problem starts inside the building or out in the street before touching the building's line. If you are a tenant, reporting it to management in writing makes it easier to discuss protecting the shared line. Cantley first inspects your building, checks the drains below street level and the point where the line joins the sewer network with a camera, explains the cause, and only then fits the backflow valve.

Most of the masonry apartment buildings in Cihangir, Galata and Tarlabaşı were built in the late nineteenth and early twentieth centuries. In buildings that were later split into flats or turned into hotels or short-term rentals, the bathrooms and kitchens that were added were connected to old cast-iron shared stacks with too little fall. The result is a tangle of lines that can block in several places at once. On the slopes of Kasımpaşa, the load coming from the upper street collects at the connections in the street below.

In the basement kitchens of restaurants, cafés and bars around Karaköy, Galata and İstiklal Caddesi, the drain outlet can sit below the level of the sewer. For this reason the backflow valve is usually fitted on the last section of the building's line before it reaches the sewer network, either inside a manhole or on the basement line. In pedestrian zones we plan the work for quiet times so that neighbouring businesses are not affected, and in tight spaces we work with portable equipment.
