Quick answer
Fox Plumbing provides non-invasive water leak detection in Springs, using harmless tracer gas and a detector to locate hidden pipe leaks without digging. Based in Benoni and serving the East Rand, owner Evan Pretorius is a qualified registered plumber with more than 20 years of experience. Most leaks are found within the hour, although difficult pipe layouts can take longer.
Signs you may need water leak detection
An unexplained increase in water use, a persistent damp patch or wet ground during dry weather can point to a hidden leak. The place where water appears is not necessarily where the pipe is leaking: water can travel beneath floors or along walls before becoming visible.
Before booking, check accessible taps, toilet cisterns and appliance connections. If you have an individual water meter, turn off all taps and water-using appliances, allow cisterns to finish filling, then check whether the meter continues registering use. This can indicate a leak, but it does not identify its location.
- Damp flooring, lifting finishes or peeling paint with no clear cause.
- A patch of garden or paving that stays wet when surrounding areas dry out.
- Water use that remains unusually high after checking your bill's reading period and whether the reading was estimated.
- A meter that continues recording consumption when no water should be running.
What affects the cost of leak detection?
Detection costs depend on how much pipework needs testing, access to isolation valves, the layout of the property and the time needed to narrow down the source. Several leaks or pipe branches that cannot easily be isolated can make the investigation more involved.
Fox Plumbing agrees the price upfront, and the call-out fee includes the first hour of work. Ask what the agreed scope includes and how additional time would be handled. Locating a leak and accessing the pipe for repair are separate tasks, so clarify any repair costs before authorising that work. Pensioners receive a special rate.
- The length and complexity of the pipe network.
- Access to meters, stopcocks and the areas being tested.
- Whether one or several leaks need locating.
- The time required for testing and any separately agreed repair work.
Preparing for a leak detection visit in Springs
Fox Plumbing serves Springs from its Benoni base. When booking, send your address, describe the symptoms and share photographs of any visible dampness. Mention whether the suspected pipe runs beneath a driveway, paving, a floor or a garden, and whether the property shares a meter or water supply.
Arrange access to the meter and stopcock, and let occupants know that testing may require a temporary water interruption. In a complex or rented property, involve the managing agent or owner where permission or access to shared pipework is needed. If water is escaping rapidly, close the property's stopcock if it is safe and you know which valve controls your supply.
- Keep recent water readings or bills available if unusual consumption prompted the booking.
- Point out previous repairs and provide pipe plans if you have them.
- Keep clear of wet electrical fittings; do not touch switches or equipment affected by water.

How we do the job
- 1
Discuss the symptoms and agree the price
Describe the water loss, dampness or meter movement. Confirm access arrangements, the detection scope and the price before work starts.
- 2
Check the supply layout
The plumber assesses accessible pipework, valves and visible signs of leakage to establish which section needs testing.
- 3
Prepare the pipework for tracer gas testing
The relevant section is isolated and prepared as needed, then harmless tracer gas is introduced into the pipework.
- 4
Trace the escaping gas
A detector is used to check for gas escaping through the leak and narrow down its location without digging. Most leaks are found within the hour, but this is not a guaranteed time limit.
- 5
Explain the findings and repair access
The findings guide the next decision about accessing and repairing the pipe. Non-invasive detection does not mean a buried pipe can always be repaired without opening the surface; agree any further work separately.
Common questions
Will you need to dig up my paving to find the leak? +
Fox Plumbing uses harmless tracer gas and a detector to locate leaks without digging. Repairing a pipe beneath paving or a floor may still require localised access once the leak has been located.
How long does water leak detection take? +
Most leaks are found within the hour. The pipe layout, access and the number of suspected leaks can extend the investigation. The call-out fee includes the first hour of work; clarify arrangements for additional time when agreeing the price.
Does a damp wall always mean a leaking water pipe? +
No. Rainwater entry, waterproofing problems and condensation can also cause dampness. Tell the plumber when the patch appears and whether it changes after rain or water use, rather than assuming the nearest pipe is responsible.
Will my insurer pay for leak detection? +
Cover depends on your policy and the circumstances. Ask your insurer about detection, access and repair cover, and any approval requirements before authorising work. Fox Plumbing's job insurance is separate from your household or building insurance.
How do I book a visit in Springs? +
