No Hot Water
The cause is usually an element that has gone or a thermostat knocked out by a surge. Both get tested where they stand and renewed, instead of the cylinder being written off on an assumption.
Home / Geyser Repair
Geyser repair in Alberton usually gets quoted as a replacement, and a good share of the time the tank is perfectly sound. We test the element, the thermostat and the T&P valve first, and we read the date stamp before anybody mentions a new unit, because a geyser inside its five year warranty may cost you nothing. Where the tank really has gone, we handle the replacement too.
Tell us the symptom and the make if you can see it. If you can reach the date stamp on the tank, that helps even more, because it tells us whether the warranty is still live.
Most of a geyser is repairable and the tank is the only part that really is not. Planning a new unit rather than a fix? See geyser installation in Alberton.
The cause is usually an element that has gone or a thermostat knocked out by a surge. Both get tested where they stand and renewed, instead of the cylinder being written off on an assumption.
A weeping overflow is the quiet warning before a burst. We replace the valve and check whether high supply pressure is the real cause behind it.
A geyser fed above the pressure its valve is rated for will keep failing whatever you replace. Fitting the right pressure control valve ends the cycle.
Weeping unions, perished flexible connectors and a drip tray that has rusted through. Small leaks that stain a ceiling long before anything dramatic happens.
Circulation pumps, controllers and sensors on solar systems, and the plumbing side of heat pumps. The panels are rarely the fault.
Power off, feed closed, tank drained, ceiling made safe. Then photographs, an itemised invoice and the certificate your insurer will ask for.
The standard geyser advice in South Africa is written for hard water, and it does not describe what happens in Alberton. This town runs on treated Rand Water supply, not on borehole water drawn through mineral-heavy ground, so the furred-up element and the silted tank that dominate most geyser articles are not the everyday failure here. Two other things are.
The first is pressure cycling. The City of Ekurhuleni manages demand by reducing pressure in high-consumption areas and closing reservoir outlet valves at night so storage can build back up, which is published policy. A geyser therefore sits on a line that falls away overnight and re-pressurises in the morning, every day, for years. Metal that is loaded and unloaded on a cycle fails by fatigue rather than by wear, and a tank that has taken that for a decade splits at a seam without ever having looked unwell.
The second is the temperature-and-pressure valve, which is the one part that decides whether a fatigued tank survives. Its job is to let pressure out as the water heats. Corroding partly shut is a slow, silent process, and a valve that can no longer relieve turns every heating cycle into a stress test on the weakest seam in the cylinder. A new T&P valve costs a fraction of a geyser and we check it on every single call, including the ones we were not called out for.
Third, and specific to this country, the electrical side. Every load-shedding cycle puts the element and thermostat through a power interruption and a restart surge, and those two parts account for most of the repairs we do. Switching the geyser off at the board before a long scheduled outage genuinely extends its life, and costs nothing to do.
The rule we publish: if the tank is sound, we repair it, whatever the geyser's age. We only recommend replacement when the cylinder itself has failed, when a second repair inside a year would exceed what a new unit costs, or when the installation cannot be brought up to standard. And before we quote any of that, we read the date stamp, because a geyser under five years old is very often a warranty claim rather than a purchase.
Whatever you phoned about, these five get looked at, because four of them are what turn a small fault into a ceiling.
Four commitments, all of them things you can check afterwards.
The date stamp gets checked before a replacement is quoted. Inside five years the unit may be free.
Sound tank means repair, whatever its age. That rule is on this page so you can hold us to it.
Parts and labour on separate lines, plus photographs of the failed component.
Water mopped, insulation pulled back to dry, and the tray and overflow put right before we leave.
The questions that come up when the hot water goes.
A repair is the cheap end of this, which is why it is worth establishing whether you need one before anyone sells you a tank. An element or a thermostat is a part plus an hour or two, and a temperature-and-pressure valve is less again. A replacement is an order of magnitude above that. Coming out to test which of those you are looking at costs you nothing, and you get the figure in writing before anything is fitted.
The tank decides it, not the age. If the cylinder is sound and the fault is an element, a thermostat, a T&P valve or the overflow, repair it. Once the tank itself has split, the only honest answer is replacement. The part people miss is the warranty: most geysers carry a five year manufacturer warranty, and we check the date stamp before quoting anything, because inside that window the unit itself may cost you nothing. We would rather find that than sell you a geyser.
Not scale, which is the usual explanation and is not what happens here. Alberton runs on treated Rand Water supply through a network the City deliberately depressurises overnight, closing reservoir outlet valves so storage can build back up. Your geyser therefore sits at the end of a line that empties and re-pressurises daily, and that cycling is what fatigues a tank, seizes a T&P valve and works the element seal. Add load-shedding surges through the element and thermostat and you have the two real Alberton killers.
For a long outage, yes. Repeated power cycling and the surge as supply returns are hard on both the element and the thermostat, and those are the two parts we replace most. Killing it at the board ahead of a scheduled slot and restoring it afterwards takes that punishment away entirely, and because a full cylinder stays hot for hours you give up almost nothing by doing it. For a two hour slot it makes little difference either way.
It is the geyser telling you something, and it is worth acting on. A temperature-and-pressure valve that weeps is often doing its job against supply pressure that is too high, in which case the fix is a pressure control valve rather than a new T&P. A valve that has corroded partly shut is the more dangerous version, because the pressure it is meant to release now has nowhere to go and the tank becomes the weakest point. Either way it is a small job now and a ceiling later.
A burst cylinder and the soaking it causes sit inside almost every household policy written in this country, so lodge the claim before reaching for your own money. Two practical things decide whether it pays smoothly. Your insurer will want the invoice split into parts and labour rather than a single figure, and where a compliance certificate applies they will want that too. We itemise as standard and issue the certificate on the day, so the claim is not held up waiting on us.
Usually one of three things. A thermostat that has drifted or failed low, an element that has partly burnt out so it heats but cannot keep up, or a mixing problem where cold is bleeding into the hot side through a failed mixer cartridge somewhere in the house. The third one fools people, because it looks exactly like a geyser fault and no amount of work on the geyser fixes it. We test for it before condemning anything.
Yes. On solar systems the faults are usually in the circulation pump, the controller or the sensors rather than the panels, and on heat pumps it is typically the fan, the sensor or a refrigerant issue that needs a qualified technician alongside the plumbing. Either way the hot water cylinder itself, the valves and the pipework are ordinary plumbing and we handle those. If the system is beyond economic repair we say so rather than keep billing you visits.
