Does a plumber or electrician fix a geyser?+
Usually a plumber handles the actual repair or installation — the tank, pipes, valves, and internal electrical parts like the heating element and thermostat. But the Electrical Certificate of Compliance (CoC) for the connection itself is issued by a registered electrician, not the plumber — many installers work as a pair, or hold both qualifications, so confirm upfront whether the CoC is included in the job. An electrician gets involved directly when the fault is upstream of the geyser itself — a tripped breaker pointing to a wiring fault elsewhere on the board, or a problem with a dedicated wall switch or timer.
How much do plumbers charge to install a geyser?+
For planning, a standard callout/repair (element, thermostat, valve) often falls around R800–R2,500 in labour, excluding parts. A full 150L electric geyser replacement — unit plus standard installation — typically totals R6,500–R15,000. Geyser size, access, and how much of the existing plumbing/electrical needs to be brought up to SANS 10254 standard move the final number, so use a written site-specific quote rather than treating any range as a guarantee.
How long does a geyser installation take?+
A straightforward like-for-like replacement is commonly done in three to six hours. Ceiling-space access, an unusual mounting position, or bringing older plumbing/electrical work up to current standard (drip tray, pressure/vacuum valve, isolating valve) can extend the job — the plumber should explain what's included before starting.
What is required to install a geyser correctly?+
A correct installation under SANS 10254 needs a drip tray under the geyser, a pressure relief valve, a vacuum breaker, an isolating valve, and (for electric geysers) a compliant electrical connection signed off with a Certificate of Compliance. Skipping these isn't just a compliance technicality — it's a common reason insurers and geyser manufacturers cite when refusing a claim later.
