Leak detection
Ramadan Drain CleaningAcoustic leak listening in Andalus
Acoustic leak listening in Andalus requires precision because the flats are numerous and the pipes sit close together in the stacks. Andalus is a co-operative residential suburb in Farwaniya, mostly apartment blocks of six to ten storeys on shared main supply lines.
When it works
When listening isthe right tool.
Listening works on one case only: a line under pressure losing water right now.
01
You hear water with taps shut
Late at night when the house goes quiet you can hear water running with every tap closed. That is the same sound we follow, except the probe hears it on the pipe instead of in the room.
02
A faint tremor in the tile
Put your hand flat on the tile above the pipe run. Sometimes you feel a faint tremor, because water escaping under pressure shakes the pipe and the bedding around it.
03
The sound rises near one spot
Walk the length of the pipe run and if the sound rises at one place and falls off past it, you are close to the opening. The sound is loudest directly over where the water leaves.
04
It stops when the valve closes
Close the main valve, and if the sound fades the source is a pressurised line. If it keeps going unchanged, it is not coming from the supply at all, and that is a different job.

What setsthis area apart
Andalus blocks are relatively modern with standardized pipework, but the branch lines from the main riser to each flat run inside walls and columns. When a branch line inside a wall leaks, the sound travels through concrete and mortar, making the height hard to fix. We use acoustic listening directly on the wall inside and out to narrow the area, and then ask the tenant to stop using water for an hour or two so the hiss becomes clearer.
Andalus is a co-operative suburb in Farwaniya governorate, located near the Fourth Ring Road with multi-storey residential blocks.
Most Andalus leaks occur in branch pipes inside wall columns, not in the main lines beneath the ground.

How we listen
Four steps on thesound.
The order is what turns a sound into a location instead of a guess.
We quieten it and charge the line
We stop the washing machine and any noisy unit nearby, and make sure the line is open and pressurised, because listening to an empty line gives nothing.
We listen at contact points
We start at valves, taps and the meter, because metal carries the sound further than the bedding does. Whichever one hears it strongest tells us which branch to walk.
We walk the run on the floor
Then we go down onto the tile itself above the pipe run, listening point by point at short spacings, noting where the sound rises and where it drops away.
We come back to the peak
We listen again on both sides of the highest reading to be sure it is the peak and not an echo, then mark that point on the tile.
Common questions
Questions about Acoustic leak listening in Andalus
Sound travels up and down through concrete, so we might hear the hiss from a lower flat when the break is above. We listen at multiple points along the riser to pinpoint the exact height.
A single flat's branch line leak does not affect the neighbour, but if the break is in the shared main line underground, all flats on that riser feel the pressure drop.
