Tank leak repair in Al Sawari Jeddah

Al Sawari is a newly built district with owner-occupied villas and residential apartments, and tank ages and types are mixed here. Some tanks are new, others older, and piping systems vary widely, linking buildings to rooftop and underground storage. A leak may come from the tank itself or from inlet and outlet pipes, and finding its source requires closing the float valve and outlet, then careful level monitoring.

  • Potable-rated materials

    Linings and disinfectants cleared for drinking water tanks, not general-purpose products.

  • You get the downtime first

    How many hours the tank is out of service, told before we start rather than after we finish.

  • A first-draw flush

    We run the first draw off after refilling, and the tank is not handed back until the water runs clear.

  • Ground and roof tanks

    Villas, apartment blocks and premises that need a written record of each visit.

Why the job is different in Al Sawari

Buildings here are relatively new and tanks, both underground and rooftop, are of mixed age and type, some metal and some concrete. The ongoing urban development means some tanks have not yet seen many years of service. The method is set out in full on our Tank leak repair service.

The first reason

Rooftop tanks of mixed construction

Villas have rooftop tanks of metal or concrete, exposed to direct sunlight and seasonal expansion and contraction. Leaks begin with rust or hairline cracks in concrete, or at pipe entry points.

The second reason

Inlet and outlet pipes of varied age

Apartment buildings have old and new pipes running together and crossing walls and foundations. A leak may be at the point where a pipe enters the tank or in the pipe itself if it is old galvanised steel.

The third reason

Water pressure varies with season and demand

Summer brings high consumption and pressure fluctuation; winter brings lower demand but sometimes higher pressure. A small leak may only show under certain pressure, so monitoring after valve closure is essential.

Before treatment

Where the water leaves decides how it is repaired

A mixed, newly built district north of Jeddah between King Saud Road and Prince Abdulmajeed Road, with Aabir Al Qarat Street crossing it. Bounded by Taybah to the east, Al Firdaws to the south, and Al Yaqut and Al Zumurrud to the west.

Damp and salt on the outside wall

Fine cracks in concrete tank walls start from seasonal expansion and summer heat stress, widening under water pressure.

The kind of crack

Rust in metal rooftop tanks begins inside where water pools and sits, especially if tanks are not cleaned regularly.

The corner where a concrete floor meets a wall

The wall to floor junction

Inlet and outlet pipe leaks occur at entry points where the pipe meets the tank rim or at old connection joints.

Water pipes passing through a concrete wall

Pipe entries

Underground tanks in villas face groundwater pressure and soil moisture, causing cracks in the floor or walls.

How we work

  1. 1

    Inspect and locate the leak

    We close the float valve and the outlet, mark the water level and watch it fall, then check the fittings and the wall beside it. That separates a tank leak from a pipe leak or a float valve that never shuts.

  2. 2

    Drain, clean and dry

    We empty the tank, lift the sediment off the base, wash back to sound concrete and let the surface dry. No repair holds on a damp or dusty face.

  3. 3

    Repair the cracks and the entries

    We cut the crack open, fill it with a non-shrink mortar, inject anything still weeping and rebuild around the pipe sleeve. A joint that moves takes a flexible detail, not a rigid one.

  4. 4

    Refill, test, then sterilise

    We refill, read the level again to confirm the drop has stopped, then sterilise before the water is used, because the tank has been open with tools and hands inside it.

What tank leak repair includes

  • A technician inspecting with a flashlight

    A marked level test

    A reading before and after with everything shut, which establishes that the loss is the tank and not the plumbing.

  • A metal floor drain

    Draining and sediment removal

    Water and silt out of the base, so the floor and the walls can be seen as they really are.

  • A spray nozzle in close detail

    Pressure wash and dry back

    The weak layer and the dust come off, because a repair only holds on sound concrete.

  • A gloved hand applying bait into a joint

    Cracks opened and filled

    The crack is cut open and filled with a non-shrink mortar, and anything still weeping under water pressure is injected.

  • The visit report being written on a clipboard

    Refill and a recorded test

    We refill, read the level again and write the reading down, so the result is not a matter of opinion.

  • A clean kitchen counter after treatment

    Sterilised and back in service

    A wash and a sterilisation once the material has cured, and guidance on running the first fill off before the water is used.

The character of Al Sawari

Mixed district: shops at street level with homes above them

Al Sawari mixes villas with apartment buildings, so tank types and systems vary widely. Villas have separate rooftop and underground tanks, apartments may have shared central systems that are more complex, and repair approaches must adapt to each building type.

Questions about this district

How do we know if the leak is in the tank or the plumbing?

We close the inlet and outlet valves and watch the level. If it drops, the leak is in the tank itself. If it holds steady, the leak is in the pipes.

Is a concrete tank better than metal in Al Sawari?

Metal tanks are older and prone to rust and holes; concrete tanks crack under pressure and thermal stress. Each has its weak point.

Can we seal a small leak with filler rather than full repair?

No, filler is temporary only. Proper repair requires draining, cleaning and drying the tank, then repairing the crack or pipe entry itself before any lining or coating.

Will recoating the tank interior stop a slow leak?

It may slow it but not stop it. If there is a crack or hole, coating masks it temporarily and water finds a path eventually.

Can we repair a pipe leak from outside the tank?

If the leak is at the pipe entry point, we may repair it from outside, but internal pressure may require draining the tank first.

How many times should we test the tank after repair?

We refill the tank post-repair and monitor it for hours, confirming stable level before the system runs at full capacity.

How much does tank leak repair in Al Sawari cost?

It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Al Sawari.
