Geyser Burst? Here's What to Do in the First Hour
If your geyser has just burst, do these four things in order, before you call anyone: switch off the geyser at the DB board, close the main water supply at the stopcock outside, photograph everything for the insurance claim, and call a PIRB-registered plumber. A typical Cape Town geyser replacement in 2026 runs R5,500 to R12,000 including a SANS 1307-compliant geyser, installation, and the SANS 10254 CoC your insurer will ask for. The rest of this guide explains the claim, how to choose your replacement, and how to prevent the next burst.
Open your distribution board (DB board) and switch off the isolator labelled 'geyser'. If it isn't labelled, it's the breaker tripped or the one near the top labelled 20A or 30A. Switching off the supply prevents the empty element from burning out and causing further damage.
Find the stopcock outside your home, usually near the boundary wall or in the front garden. Turn it clockwise to close. Water will continue to drain from the geyser into the overflow for several minutes; that's normal.
Photograph the ceiling, the visible leak, water damage to walls, the geyser unit itself, and any damaged contents. Note the time. Most South African insurers require this for a water-damage claim, and incomplete documentation is the most common reason claims are reduced or rejected.
Your insurer will ask for the SANS 10254 plumbing CoC. Only a PIRB-registered plumber can legally issue it. If you call a cheap unregistered plumber and they finish the job, you may have to pay a second plumber to do the certification — or your claim may be reduced.
ClicknDone Pros target a 60- to 90-minute response window in the Cape Town metro for emergency calls. Funds are held in escrow until you confirm the work is done.
| Item | Typical 2026 cost |
|---|---|
| 200L electric geyser (SANS 1307) | R3,500 – R6,500 |

Insurance claims usually settle the replacement at depreciated value unless your policy specifies replacement value.
Most South African home insurance covers the geyser itself and the water damage to ceilings, walls, floors, and contents — provided the work is done by a PIRB-registered plumber and certified with SANS 10254. Common reasons claims are reduced: no documentation of the burst, work done by an unregistered plumber, the geyser was past its 5-year warranty and wasn't serviced, or signs of corrosion that suggest neglect.
A geyser's anode rod should be inspected every 5 years. The thermostat should be set at 60°C — higher temperatures accelerate corrosion and wear. A geyser blanket (insulation jacket) reduces stress on the element. Annual servicing by a PIRB plumber catches anode wear before it becomes a burst.
Geysers fail more often in winter because the cold water entering the tank causes greater thermal stress on the element and tank seams. May to August is peak season for bursts in the Western Cape. If your geyser is over 5 years old, consider booking a winter inspection before the rain.
