Geyser Repair
in Rustenburg
Geyser repair in Rustenburg starts with a test, not a sales pitch: the element, thermostat, valves and wiring are checked before anyone mentions a new geyser. If your hot water runs brown after an outage, that grit is often where the fault began.

Most geyser faults are a part, not a new geyser
Most geyser call-outs come down to one of these. The test on the day says which.
-
No hot water, light still on
Power reaches the geyser but the water stays cold. A meter test shows which part has given up, without touching the cylinder.
-
Burnt element or stuck thermostat
Matched to the geyser's rating, then checked with a meter before the ceiling hatch goes back on.
-
Overflow pipe dripping
A pressure control valve that no longer seals, or a temperature and pressure valve doing its job. The test tells the two apart.
-
Tripping the electricity
A leaking element or damp wiring at the thermostat. Found with an insulation test, not by switching things on and hoping.
-
Brown or cloudy hot water
Sediment lying in the bottom of the cylinder. Drained out through the drain valve, and the inlet strainer cleaned.
-
Burst or leaking cylinder
Water off, power off, photos taken for your insurer and a replacement quote. See geyser installation.
Why Rustenburg geysers end up full of grit
Rustenburg Local Municipality publishes its own tap-water results. In April 2025 only 66.7% of its network samples met the SANS 241 limit for turbidity, the cloudiness caused by fine particles in the water. In May 2025 it was 62.5%. By June it was back at 100%, but for two months a lot of what came out of Rustenburg taps carried silt.
The grit has a source. The municipality supplies about 134.68 megalitres a day against a demand of 223.08, so supply here is rationed by time: night shutoffs, and a water-shedding timetable in December 2024. When the water comes back, the municipality warns that recovery can take up to 48 hours. On top of that, 778 km of its 1,477 km of water mains are asbestos cement, and a broken main lets mud and sand into the line.
A geyser is the slowest-moving water in the house, so it is where that dirt settles. It sinks to the bottom of the cylinder and builds up around the element, which then runs hotter than it should. The drain valve clogs, and the strainer in front of the pressure control valve fills with silt until the valve stops seating and the overflow starts to drip.
That is why a geyser call-out in Rustenburg checks more than the element. The inlet strainer is opened and cleaned, the cylinder is drained until it runs clear where the drain valve allows it, and the valves are tested under pressure. Whatever failed is shown to you, in a photo or as the old part in your hand.
Replacement only comes up when the cylinder itself leaks or the installation cannot be made safe. A burnt element, a stuck thermostat and a tired valve are all parts, and parts cost a fraction of a geyser.
When the water comes back after an outage, flush the line through a garden tap until it runs clean, and only then use the hot taps. The first rush of grit goes onto the lawn instead of into the geyser.

Repaired before replaced
A new geyser is only quoted when the cylinder leaks or the installation cannot be made safe.

What does a new geyser element and thermostat cost in Rustenburg?
The parts are the smaller part of the bill. Elements sell for a few hundred rand, and people who have claimed through their insurer report paying about R1,000 for an element and thermostat with the call-out covered. Rustenburg plumbing directories list hourly rates of roughly R360 to R900 in 2026. You are told the call-out fee on the phone, and the full repair price is written down before any work starts. See plumbing prices for more.
Is my geyser burst, or is it just the thermostat or element?
A burst geyser leaks from the cylinder itself: water through the ceiling, a full drip tray, or a steady run from the body of the tank. A failed element or thermostat leaves you with cold water and no leak. A drip from the overflow pipe outside is a third thing, usually a valve. If water is coming through the ceiling, switch the geyser off at the isolator and close its stopcock before you do anything else.
Why is my geyser not heating when the light is on?
The light on the isolator only shows that power reaches the geyser. If the water stays cold, the element has usually burnt out or the thermostat is not switching it on. Both are tested with a meter, and both are replaced as parts.
Why is my geyser dripping from the overflow pipe on the roof?
A steady drip usually means the pressure control valve no longer seals, often because silt has got into its strainer. A gush of hot water while the geyser heats points to the temperature and pressure valve, which opens when the water gets too hot, so the thermostat is checked too. The test on the day tells which it is.
Why does my geyser keep tripping the earth leakage?
Something in the geyser is leaking current to earth, most often an element whose sheath has cracked, or water reaching the thermostat. Leave it off at the isolator until it is tested. Resetting it over and over can burn out the wiring as well.
Will my insurance pay for a thermostat, or only for a burst geyser?
That depends on your policy. Many cover a burst geyser and the damage it causes, but treat a failed element or thermostat as wear and tear. Read your schedule or ask your broker before you claim. Either way, you get an invoice that names the fault and each part, with photos, which is what an assessor asks for.
Can you show me the old part you took out?
Yes. Every part that comes out of your geyser is shown to you or left with you, and photographed if you are not home.
Why is the hot water coming out brown?
Brown hot water with clear cold water usually means sediment has built up in the geyser. In Rustenburg that is common after outages, when the network refills and fine silt gets through. The cylinder is drained through the drain valve until it runs clear. If the cold water is brown as well, the dirt is coming from the supply, and running an outside tap until it clears helps.
