When water is running across the floor, nobody wants to waste time guessing where the main shut off valve is. Yet that happens all the time. Homeowners know they need to stop the water, but they have never been shown exactly where to look.
In Sandton properties, the shut off point depends on the age of the home, the estate layout, and whether the property has been renovated. The good news is that there are a few common places to check first.
Common places to find the main shut off valve
- Near the boundary wall where the municipal line enters the property
- Inside or next to the water meter box
- In the garage on the incoming mains line
- Near an outside tap where the main supply branches into the house
What does it usually look like?
It may be a lever valve, a round stopcock, or an older style isolation valve. In some homes it is easy to spot. In others it may be hidden under a small cover or inside a service box.
What should you do once you find it?
- Turn the valve fully off
- Open a tap inside the house to confirm the supply has stopped
- Switch off the geyser if the leak affects the water supply to the system
- Move valuables away from the wet area
- Call a plumber for the permanent repair
What if you cannot find it?
If you cannot locate the shut off point quickly, do not keep searching while water continues damaging the property. Call for help immediately. A plumber can often guide you over the phone while travelling to site.
Why this matters
Knowing the shut off location before an emergency happens can reduce damage dramatically. It can mean the difference between a manageable repair and a flooded ceiling, warped cupboards, or a damaged floor.
