Pool Leak Detection Specialists in KwaZulu-Natal

Losing water from your swimming pool is not normal in Durban’s climate. If you are topping up more than once a week, you need professional pool leak detection.

Fornez is KwaZulu-Natal’s dedicated pool leak detection company. We do not do general plumbing. We find leaks in swimming pools every day for homeowners, estates, schools, hotels and resorts across Durban, Ballito and Umhlanga.

Using acoustic listening, tracer gas and underwater diving inspections, we pinpoint leaks in pool shells, pipes, skimmers and drains without draining your pool or breaking your paving.

Two Services, One Speciality

Domestic Pool Leak Detection

For homes, complexes and estate pools. We use low-pressure testing and sensitive acoustic gear to protect older PVC pipes and delicate finishes.

Why Pools in KZN Leak

Durban and the North Coast present unique challenges:

  • Soil movement: clay soils in Hillcrest and Umhlanga shift, stressing concrete shells
  • High water table: in Ballito and Salt Rock, hydrostatic pressure pushes up on pool floors
  • Salt air corrosion: coastal properties see faster deterioration of metal fittings
  • Ageing estates: many 15 to 20 year old pools in complexes now have multiple small leaks

This is why a plumber with a listening stick often misses the real problem. Pool leak detection requires pool knowledge.

Our Non-Invasive Pool Leak Detection Process

Step 1: Confirm the water loss

We start with a bucket test to separate evaporation from a real leak. In KZN summer, evaporation is 20-25mm per week. More than that indicates a leak.

Step 2: Pressure test every line

We test suction, returns, cleaner lines and heating circuits individually to isolate the leaking pipe.

Step 3: Find the exact spot

For underground pipes we use a safe hydrogen-nitrogen tracer gas. For shell leaks we dive the pool and use dye testing around lights, skimmers and cracks.

Step 4: Report and mark

You receive a detailed report with photos, marked leak locations and repair recommendations with a quotation for the required repairs the same day.

Step 5: Advise and Quote

We provide repair options and a quotation for those repairs that same day.

This process works for all pool types: marbelite, fibreglass, vinyl liner and tiled concrete.

How Much Water Is Your Pool Losing?

A small 2mm hole in a return line can lose over 7,000 litres per week. That is R800 to R1,200 on your eThekwini water bill monthly, plus chemical costs and pump wear. Early pool leak detection typically pays for itself in under 60 days..

Pool Leak Detection FAQs

1. How do I know if my pool is leaking or evaporating?

Do a bucket test for 24 hours. If the pools water level drops more than the buckets, you have a leak and need leak detection for your pool.

2. Will you need to drain my pool?

No. All our domestic and commercial leak detection testing is done with the pool full.

3. Can you find a leak under my paving or deck?

Yes. Our tracer gas and acoustic equipment pinpoints leaks within 10cm under paving, concrete and even pool decks.

4. How long does it take?

Most domestic pools take 90 to 120 minutes, while commercial pools can take 3 to 5 hours depending on the pool size.

5. Do you repair the leak?

Yes, we professionally repair pool leaks. Once we have completed the leak detection process and identified all issues affecting the pool system, we will provide a detailed quotation outlining the required repairs. Upon approval, our team will proceed with the necessary work to restore the system efficiently and to a high standard.
