Leak Detection in Pretoria: Hidden Leaks, Leaking Toilets, Burst Pipes and High Water Bills
Leak detection in Pretoria costs R1,200 to R3,000 using acoustic, thermal or tracer-gas methods in a Pretoria plumbing guide dated March 2026, with the repair quoted separately. Section 26 of the City of Tshwane Water Supply By-laws states that a customer gets no reduction for water lost in the installation, so a hidden leak is paid for until it is found.

A sudden jump on the water bill, a meter that turns with every tap closed, a damp patch on a wall or a cistern that never stops filling are the usual reasons to call for leak detection.
Check for a Leak Before Calling Anyone
The City of Tshwane publishes this test for a leak on a property:
- Close all taps on the property, indoors and outdoors.
- Isolate the geyser if possible.
- Check whether the counter digits on the water meter are moving.
- If they move, check toilet cisterns, taps, exposed pipe work and damp patches on walls with pipes in them.
- If nothing is visible and the digits still move, the leak is underground.
A moving meter with no visible cause is where leak detection starts.
Where Hidden Leaks Are Found
| Location | Sign | Related work |
|---|---|---|
| Toilet cistern | Water trickling into the bowl, cistern refilling on its own | Replace the inlet valve or flush mechanism |
| Geyser and its valves | Constant drip from the overflow, water in the drip tray | geyser installation in Pretoria |
| Pipes in walls and behind showers | Damp or bubbling paint, lifting tiles, musty smell | bathroom renovations in Pretoria |
| Pipes above the ceiling | Stain or sag with no roof or geyser fault | ceiling repairs and installation |
| Under the floor slab | Warm or damp floor patch, meter moving | Pipe re-routing or slab repair |
| Garden line, meter to house | Wet patch or green strip in the lawn, meter moving | Pipe repair; may qualify for the City's leak claim |

Acoustic listening picks up the sound of water escaping under pressure. Thermal imaging shows the temperature difference that a hot or cold leak makes in a wall or floor. Tracer gas is pushed through an emptied pipe and detected where it escapes. The method is chosen by where the pipe runs and what it is buried in.

|---|---|
| Section 26 | A customer is not entitled to a reduction in the amount payable for water wasted or for water losses in a water installation |

The City of Tshwane's Internal Leak Claim
The City of Tshwane accepts a claim for an undetected, non-visible leak on a residential property, subject to conditions on its internal water leak page:
| Condition | Detail |
|---|---|
| Where the leak is | Between the water meter and the connection point of the house |
| Excluded | Geysers, toilets and any leaks in the house or in walls |
| Repair work refunded | Up to R1,000 |
| Water loss | Up to R2,000, calculated from consumption records |
| How often | One claim per event per year |
| Documents | A letter, the plumber's invoice detailing the repair and materials, a sketch or photo of the leak, and an affidavit stamped at the nearest SAPS station |
| Other insurance | Claim on any alternative insurance cover first |
The repair invoice from a leak detection job lists the leak's type and location, which is what the City asks for.
Water Restrictions and High Consumption in Tshwane
The City of Tshwane's notice of 27 August 2026 states that its Level 1 water restrictions were never withdrawn and still apply, and that it will impose fines and restrict supply to consumers who do not comply. On the same date the City reported consumption of 932 Mℓ per day, 265 Mℓ per day above its permitted limit, and asked customers in Regions 1, 3, 4 and 6 to cut use. The notice lists suburbs from Soshanguve to Faerie Glen and Rooihuiskraal under its highest-consuming reservoirs, and asks residents to check toilets and taps for leaks regularly.
Burst Pipes and Leaking Toilets
A burst pipe is isolated at the nearest valve or the main stopcock, then cut back and joined, or re-routed if the old line is corroded along its length. A leaking toilet is usually the inlet valve or the flush seal, a part swap rather than a new toilet. Under section 57 of the Consumer Protection Act 68 of 2008, a repair's new or reconditioned parts, and the labour that fitted them, carry three months of statutory cover from the installation date. Misuse cancels that cover, and normal wear and tear falls outside it.

Pretoria Home Repairs: Frequently Asked Questions
How much does leak detection cost in Pretoria?
A Pretoria plumbing guide dated 26 March 2026 lists water leak detection using acoustic, thermal or tracer-gas methods at R1,200 to R3,000, with the repair quoted separately. A national guide reviewed in September 2026 gives R850 to R5,000 per detection visit across domestic, commercial and more complex jobs, with repairs priced separately.
How do I check for a water leak on my property?
Close every tap indoors and outdoors, isolate the geyser if possible, and watch the water meter. If the digits still move, check toilet cisterns, taps, exposed pipes and damp walls; if nothing is visible and the digits keep moving, the City of Tshwane's own guidance says the leak is underground.
Will the City of Tshwane reduce my bill for a leak?
Not as a rule. Section 26 of the City's Water Supply By-laws says a customer is not entitled to a reduction for water wasted or lost in a water installation. The City's conditional scheme accepts one claim per event annually for an undetected, non-visible leak between the meter and the house, with repair costs capped at R1,000 and water loss at R2,000; applicants must state whether it was above ground or underground.
Does the City's leak claim cover a leaking toilet or geyser?
No. The City of Tshwane's internal-leak claim excludes geysers, toilets and leaks inside the house or in walls. It covers non-visible leaks between the water meter and the connection point of the house.
Is a leaking toilet worth fixing quickly?
Yes. A cistern that runs into the bowl wastes water all day, and section 55 of the City of Tshwane Water Supply By-laws says no customer may permit a pipe or water fitting to leak and the owner must repair the part causing it.
What happens after the leak is found?
The leak is marked and the repair is quoted: a pipe section, a valve, a cistern mechanism or a joint behind tiles. Opening and making good walls, floors or ceilings is listed separately.
