A leaking geyser wastes water and electricity at the same time, because the element keeps reheating water that is escaping.
Switch it off at the DB board first, then diagnose. Related detection methods sit under Leak Detection Pretoria.

Get a Geyser Leak QuoteWhat Is Actually Leaking
| Symptom | Likely cause |
|---|---|
| Steady drip from the overflow outside | Working pressure valve, or a failed one. Not always a fault. |
| Water in the drip tray | Failed connection, valve or the cylinder itself. |
| Warm ceiling stain below the geyser | Cylinder or hot line failure. Isolate immediately. |
| Electricity bill up with no usage change | Hot water escaping somewhere on the line. |
Repair or Replace
Valves, elements, thermostats and connections are repairs. A leaking cylinder is not; once the tank itself has corroded through, replacement is the only outcome. Most domestic geysers run eight to twelve years.

A geyser replacement must be installed to SANS 10254, with a drip tray, vacuum breakers and correct overflow routing. Those items are exactly what a plumbing certificate inspection checks.

Frequently Asked Questions
Why does my geyser overflow drip?
Some discharge from the overflow during heating is normal, as water expands. A continuous drip usually means a failed pressure control valve or mains pressure above what the installation allows.
Is a leaking geyser an emergency?
If water is reaching a ceiling or electrics, yes. Switch off the geyser breaker and close its isolating valve. A slow drip into a correctly plumbed drip tray can wait for a weekday booking.
Does insurance cover a burst geyser?
Most household policies cover a burst geyser and the resulting damage, and many insurers require you to use their appointed contractor. Call the insurer before you book anyone.
