Geyser Repair
Kempton Park
Geyser repair in Kempton Park starts with finding the part that failed, whether the element, the thermostat or a valve, and showing it to you before anything is replaced.
Six geyser faults that are a part, not a new cylinder
Each one is tested before it is replaced, and each is cheaper than a geyser.
Element
No hot water and an isolator that trips usually point here. The element is tested with a meter before a new one goes in.
Thermostat
Water that is lukewarm, or far too hot, points to the thermostat. It is checked against the real water temperature, then reset or replaced.
Pressure control valve
The valve on the cold supply that holds the geyser below its rating. A worn one shows up as weak hot water or a drip that never stops.
Temperature and pressure valve
The safety valve on the cylinder. When its seat wears, water runs from the overflow pipe outside. It is tested and replaced if it no longer seals.
Vacuum breakers
Small valves on the hot and cold sides that stop the cylinder siphoning empty when supply drops. Leaking ones are swapped out.
Drip tray and overflow pipes
A tray under the geyser and pipes that end outside, where a drip gets noticed. Cracked, blocked or missing ones are put right.
The drip your insurer will call wear and tear
Home insurance generally pays out when a geyser bursts. Absa's homeowners cover, as one example, lists the "bursting, leaking, or overflowing of geysers" among the damage it pays for. The same policy excludes "loss or damage resulting from a lack of maintenance, gradual deterioration, or wear and tear". Between those two sentences sits the slow drip.
A geyser rarely goes from sound to burst overnight. It tends to give notice first: a valve that lets by, an overflow pipe that runs a little every morning, a drip tray holding water, a brown ring spreading across the ceiling board. Each of those is a part asking to be replaced. Ignored for a season, the same drip can rot the ceiling under the tray and the timbers the geyser stands on.
Ekurhuleni's Water Services By-laws are written so that somebody notices. The overflow of a fixed water heater, and its heat-expansion pipe, must discharge where the water "will be readily visible", and never into a sewer or a stormwater drain. The SANS 10254 compliance tables plumbers work to say the same of the drip tray: its pipe goes to the outside of the building, easily seen. That pipe on your wall or roof edge is there to be watched.
Visibility works both ways. A drip that anyone in the garden could see for months is hard to describe as sudden, and an assessor looking at a collapsed ceiling under a long-leaking tray can ask how long the water ran. Kwikot, the geyser maker, adds that an insurer "is within their rights to reject the claim" where the installation is not compliant. A geyser repaired when it first drips is the cheapest evidence that the house was looked after.
So the first drip is the repair, not a warning to file away. In most cases it is one valve or one element, and the paper that comes with fixing it (what failed, what was fitted, when) belongs with your policy documents. If a real burst ever does follow, that invoice shows the geyser was maintained, and the claim starts from firmer ground.
If water runs from a pipe on your outside wall or roof edge, have the geyser checked that week and keep the invoice that names the part. It is the simplest proof that the next leak, if there is one, was sudden.
What a geyser fault usually turns out to be
Read across: what you notice, the part most often behind it, and what the visit checks first.
Geyser faults, Kempton Park homes
| What you notice | What it usually is | What it needs |
|---|---|---|
| No hot water, the isolator trips | An element shorting to earth | Element tested with a meter, replaced if it fails |
| Water barely warm, or scalding | Thermostat stuck or set wrongly | Water temperature measured against the setting |
| A steady drip from the overflow outside | Temperature and pressure valve, or the pressure control valve, letting by | Incoming pressure measured, then the failing valve replaced |
| Strong cold, weak hot | A clogged strainer or a worn pressure control valve | Strainer cleaned, or the valve replaced |
| Water in the tray, a brown mark on the ceiling | A leaking fitting, or a split cylinder | Cylinder inspected: fittings repaired, a split tank replaced |
A split cylinder cannot be patched. Almost everything above it on the board can be repaired.
Four things a geyser repair visit sticks to
Built from what people complain about most after a plumber has been: surprise charges, guesswork and a new geyser they did not need.
The charge, explained on the phone
When the plumber phones you back, you hear what the visit costs, what it covers, and what you owe if you decide not to go ahead.
A test you can watch
Element, thermostat and valves are checked with a meter or a gauge. A part is replaced only after it has failed that test in front of you.
Parts before a new cylinder
A new geyser is quoted only when the tank itself leaks or the installation cannot be made safe. Otherwise the fix is the part.
An invoice that names the part
What failed, what went in and the labour, on separate lines. If you ever claim, it shows the geyser was maintained.
From a cold shower to hot water, in four steps
No step happens without your go-ahead, and no time is promised that has not been booked with you.
Describe the symptom
Send the form with what the geyser is doing: cold, dripping or tripping. If water is leaking, switch it off at the board first.
A plumber phones back
A few questions narrow it down, such as the geyser's age and where the water appears. The visit is booked and its charge explained.
Test, show, price
Element, thermostat and valves are tested on site. You see the reading or the failed part, then get the repair price in writing.
Repair and check
The part is fitted, the cylinder filled before it heats, and the overflow watched until it stays dry. The invoice lists every part.

Geyser questions from Kempton Park homes
Ask yours in the call-out form and the plumber answers it when they phone.
Before anyone drives out, how is a geyser repair charged?
In two parts. The call-out charge is explained when the plumber phones you back, and the repair is priced in writing once the faulty part has been found. Nothing is fitted until you accept that price.
As a rough market guide only, online cost guides put a replacement element at about R400 to R800 and a thermostat at about R300 to R600, with a pressure control valve costing more. Your quote depends on the geyser and what failed. How a written quote should be set out, line by line, is on the plumbing prices page.
There is a wet patch on the ceiling board below the geyser. Is that a burst?
Not necessarily. A burst cylinder leaks from the tank itself and keeps leaking while water reaches it. A ceiling stain can also come from a fitting, a valve or an overflowing drip tray, and those are repairs.
Turn the geyser's breaker off, shut the valve on its cold feed if it is safe to reach, then send the form. The plumber tells you which it is once it is in front of them.
A pipe near the roof keeps dripping onto the paving. What is it?
Almost certainly the geyser's overflow or drip-tray pipe. Ekurhuleni's by-laws require it to end where the water can be seen, so that a fault gets noticed.
A steady drip usually means a valve is letting water by, often the temperature and pressure valve or the pressure control valve. It is a small repair now and a ceiling later.
Why does the hot tap only trickle when the cold runs fine?
The usual suspects are a clogged strainer or a worn pressure control valve on the geyser's cold feed, which starves the hot side only. Both are checked with a gauge on the visit.
In older homes the hot pipe itself can be the problem. An industry paper on South African homes found that 90% of failures in a common type of galvanised steel pipe were on hot-water lines, which is one reason those pipes were replaced with copper and plastic. If yours are galvanised, see water pressure repairs.
Can the element just be replaced, or do I need a whole new geyser?
If the cylinder is sound, an element is replaced on its own. The geyser is drained, the old element removed, the new one fitted and tested, and the cylinder refilled before it heats again.
A new geyser comes into it only when the tank leaks or the installation cannot be made safe. You are shown why before anything is quoted.
The power came back after a cut and now there is no hot water. What should I check?
Start with the free checks: the geyser's breaker or isolator on the board, and any timer, which Eskom reminds households to reset after power returns. Eskom adds that restored power can arrive with a brief surge, which may damage electronic controls.
If the breaker trips again when you reset it, leave it off and send the form. That pattern usually points to the element or the wiring at the geyser, and it should be tested before it is switched back on.
Should I phone my insurer first, or a plumber?
Stop the water first, then do both. Switch the geyser off, close its supply valve, and photograph the damage before anything is moved.
Insurers set their own claim steps, so phone the claims line as soon as you can. The repair invoice names the fault and every part fitted, which is the detail an assessor asks for.
Will you tell me if my geyser is not worth repairing?
Yes, and you will be shown the reason. A leaking cylinder cannot be repaired, and an installation that cannot be made safe needs more than a part.
If the tank is sound, the repair is quoted instead. When a replacement is the honest answer, the geyser installation page explains what a compliant new installation includes.
