Leak Repair & Detection

Professional leak detection and repair services across South Africa. PIRB-registered plumbers find and fix hidden leaks fast.

WHAT IS LEAK DETECTION & REPAIR?

A water leak is not always visible. Many of the most damaging leaks occur inside walls, under floors, underground, or in roof spaces — completely hidden from view. By the time visible damage appears, significant structural damage and water loss has already occurred.

Professional leak detection uses specialised equipment and techniques to locate the exact source of a leak without unnecessary excavation or damage to your property.

Common leaks we detect and repair:

  • Underground pipe leaks

  • Hidden wall and ceiling leaks

  • Leaking water mains

  • Slab leaks under concrete floors

  • Roof and gutter plumbing leaks

  • Leaking joints and fittings

  • Pool and irrigation line leaks

  • Municipal meter leaks

  • Leaking geysers and supply lines

  • Leaking toilets and cisterns

SIGNS YOU HAVE HIDDEN LEAKS

Many leaks go undetected for months.

Watch for these warning signs:

  • Your water meter is running when all taps are closed

  • Unexplained increase in your water bill

  • Damp patches on walls or ceilings

  • Peeling paint or bubbling plaster

  • Musty or mouldy smell in rooms

  • Soft or sunken patches in your garden or lawn

  • Cracking or lifting floor tiles

  • Reduced water pressure throughout the property

  • Sound of running water when nothing is on

  • Rust stains around pipe entry points

How to check for a hidden leak yourself:

Turn off all taps and water-using appliances. Locate your water meter and watch the dial for 15 minutes without using any water. If the dial moves, you have a leak somewhere in your system. Call us immediately.

COMMON CAUSE OF LEAKS

Aging and corroded pipes

Galvanized steel pipes common in older South Africa properties corrode from the inside out. By the time a leak appears the pipe wall is serverly compromised and replacement is usually required.

Tree root intrusion

Tree roots seek out moisture and will penetrate even small cracks in underground pipes. Once inside, roots expand and cause major pipe damage and blockages.

High water pressure

One of the most overlooked causes of plumbing emergencies in South Africa. Municipal supply pressure can spike significantly. Pressure above 400kPa causes accelerated wear on pipes, geysers, and fittings. A pressure reducing valve (PRV) protects your entire system.

Poor Workmanship

Incorrectly joined pipes, improper fittings, or poor sealing on previous plumbing work are a common cause of leaks — particularly in properties that have had multiple plumbers over the years.

Ground movement

South Africa’s clay-heavy soils expand and contract significantly with moisture changes. This ground movement stresses underground pipes and causes joints to shift and leak.

Thermal expansion

Hot water pipes expand and contract with temperature changes. Over years this movement causes joints and fittings to loosen and eventually leak.

HOW TO PREVENT LEAKS

Annual plumbing inspection

The single most effective prevention measure. A qualified plumber identifies early signs of corrosion, pressure issues, and failing joints before they become leaks.

Install a pressure reducing valve (PRV)

Keeps your system pressure within safe limits and dramatically reduces stress on all pipes and fittings.

Monitor your water bill

An unexplained increase in your monthly water bill is often the first sign of a hidden leak. Don’t ignore it.

Replace aging pipes proactively

If your property has original galvanised steel pipes and is more than 20 years old, consider a pipe replacement assessment before a leak forces your hand.

Fix dripping taps immediately

A dripping tap wastes thousands of litres of water per month and indicates a failing washer or valve seat. Left unattended the leak worsens and damages the fitting.

Check your toilet cistern regularly

Put a few drops of food colouring in the cistern. If colour appears in the bowl without flushing, your cistern is leaking silently — wasting water and increasing your bill.
