Tracing Hidden Water

Slow Leaks Turn Into Emergencies

Most hidden leaks start small: a pinhole in old pipe, a weeping joint under the floor, a shower waste that's lost its seal. Left alone, they rot ceilings, lift tiles and push up the water bill until something gives. If a damp patch is spreading fast or water is dripping through a light fitting, switch off that circuit and close the stopcock.

We trace leaks with acoustic listening equipment, thermal imaging and pressure testing, then open only the area where the water is escaping. In apartment buildings, that often means proving which unit or riser the water is coming from before anyone starts breaking. We repair the pipe and can give you a written report for your insurer or a municipal billing query.

Scenario by Scenario

Leak Signs and What to Do

Water Dripping From a Light

Switch off that lighting circuit at the DB board, close the stopcock and call the night line.

Stain Spreading on the Ceiling

Put a bucket under it and check upstairs. We find whether it's a pipe, a geyser or a shower above.

Meter Moving With Taps Off

Something's running. Note the reading, wait ten minutes, and book us to find it.

Leak From the Unit Above

Report it to the building manager. We trace it and confirm which unit it's coming from.

Swollen Skirting or Lifting Tiles

Usually a slow leak in the floor or wall. We pinpoint it before opening anything.

Toilet Cistern That Never Stops

Close the angle valve for now. A running cistern wastes a lot of water each month.

Why It Happens Here

The Usual Triggers Around Sandton

Hard water, ageing pipes in older houses, pressure systems in towers and the odd violent storm are behind most of these call-outs. Each note includes what to do while you wait:

Pressure in Towers and on Ridges

Apartment blocks rely on booster pumps and pressure-reducing valves to get water to the upper floors, and a ridge-top house can see very different pressure from the one at the bottom of the street. When a PRV fails open, taps bang, flexi hoses balloon and fittings start to weep. Close the unit's isolating valve, tell the building manager and call us. We replace the valve and use leak detection to check nothing behind the walls has given way.

Original Pipework That Finally Splits

Some of the older homes in Sandton still run on galvanised steel laid when the house was built. It thins from the inside for years, then one day a seam gives way behind the tiles. When that happens: main stopcock off, geyser isolator down if the water is hot, and towels against the skirting. We make it safe that night and come back to replace the corroded run rather than leave a clamp in the wall for good.

Frozen Pipes on Winter Mornings

A few nights each winter dip below zero, and exposed copper on a south-facing wall, a garden tap or a roof-space pipe can freeze solid. The split usually only shows once the sun thaws it. If a pipe is iced up, don't pour boiling water over it. Open the nearest tap, warm the pipe gently with a hairdryer, and if it starts spraying, close the stopcock and ring the night line.

The Moment the Mains Come Back

A scheduled Joburg Water shutdown or a burst main up the road can leave Sandton dry for hours. The danger comes at the end: air trapped in the lines blasts through when the supply returns, and a tired ball valve, flexi hose or geyser fitting can let go while nobody is watching. Keep the stopcock half-closed when water returns and open it slowly. If cuts keep catching you out, a JoJo tank with a booster pump carries the house until the supply settles.

Water Where It Shouldn't Be in Sandton? Do These Three Things

One: turn the main stopcock clockwise until it stops, usually at the meter or where the supply enters the house. Two: if anything hot is leaking, switch off the geyser isolator at the DB board. Three: keep water away from plugs and lift what you can off the floor. Then phone 082 550 3306, staffed all night, every weekend and on public holidays. Non-urgent bookings go to 087 700 7781.

From Phone Call to Final Repair

Three Stages of an Emergency Call in Sandton

1

Isolate, Then Phone

Close the stopcock or drop the geyser isolator first if you safely can. Then ring 082 550 3306. Day or night, a person answers, asks a few short questions and tells you what else to switch off.

2

Make It Safe on the Night

A plumber who covers Sandton arrives with the van stocked for common failures, explains what has happened and gives a fixed price before touching anything. The after-hours surcharge was already agreed on the phone.

3

Finish It Properly

If a lasting repair needs parts, daylight or a building manager's go-ahead, the night visit stops the damage and the permanent fix is booked through 087 700 7781. Either way, the workmanship is guaranteed.
