Pre-fit camera check
Line condition and diameter confirmed before valve position is chosen

Hawalli
Backflow valve installation in Salwa starts by lifting the main chamber cover and running a camera to check pipe direction, deposits and bends. We choose the valve position based on fall and pipe diameter, fit it, test full flow and confirm closure before sealing the chamber.
Dense Salwa houses have main sewerage lines running under streets toward the treatment plant, and these lines carry high pressure in summer when plants close for maintenance. The valve fits in the ground chamber before the main line connection, allowing normal flow but blocking any backflow. We open and sometimes dig out the chamber to make room for the valve around the pipe.
Salwa lies in Hawalli governorate and sits close to Salwa Co-op and Mishref Park, a district of established family homes.
After fitting, we run water at full pressure for minutes to confirm the valve closes if any backflow is attempted.
Line condition and diameter confirmed before valve position is chosen
Closest viable point to the public sewer for maximum protection
Valve set into the line without unnecessary tile breaking
Flap mechanism tested in both directions before the line is reconnected
Line filmed again to confirm valve seating and unobstructed flow channel
Correct siting verified relative to cesspit or inspection chamber position
How we work

Tell us what is happening and where, and the right equipment is loaded before we arrive.

We film the line from inside and know the kind of blockage and its exact place. No guessing.

High pressure water, a machine or a drain snake, whichever the line actually needs.

The camera runs a second pass and you see the line clear with your own eyes before we leave.
Same method, same equipment. Only the size of the job changes.

The valve itself needs no regular inspection if working correctly, but the chamber may accumulate silt that slows drainage. We recommend chamber cleaning every two years if your house has frequent blockages.
The valve stops water only, not odours or gases. If you smell sewage strongly the issue may be blocked roof vents or broken vent pipes. We check ventilation when opening the chamber.
