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

Hawalli
Installing a backflow valve in Anjafa starts by lifting the main pit cover and sending in a camera to film the internal ceiling and falls. We locate where water backs up during heavy flow and position the valve on the main drain line based on the slope. We clear debris, fit the valve and pressure-test it fully before replacing the cover.
Older Anjafa houses have deep pits beneath the front yard with drain lines connecting every bathroom and kitchen, all feeding the main pit from one direction. When street drainage floods after heavy rain, water backs up through the lines and overflows from the nearest outlet, usually the ground floor. A backflow valve stops this but must sit near the pit outlet where full pressure builds, not mid-street where flow is weak.
Anjafa sits in Hawalli governorate, an older residential neighbourhood where each property was built with its own separate pit.
We test the valve by filling the pit from an external supply line and checking that no water leaks backward through the flapper.
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.

It blocks backflow from the street only. Normal household drainage flows forward freely because the valve opens with forward pressure and closes when pressure reverses. We test it by injecting water from the external line to confirm no backflow can pass through.
After installation, we open the pit every two years to check the valve and confirm no silt has stuck the flapper open. If your street floods regularly, we check more often because debris builds wear quickly.
