No hot water at all
Usually a burnt-out element or a failed thermostat. Both are same-day repairs and far cheaper than a replacement.
Element, thermostat, valves or a full replacement — done properly, certified on the day, and quoted before we touch anything. Insurance paperwork handled.
Send it through and you'll have a call back — usually inside the hour.
Most geyser failures give you warning. Catching it at this stage is a repair. Leaving it is a new ceiling.
Usually a burnt-out element or a failed thermostat. Both are same-day repairs and far cheaper than a replacement.
A short in the element, almost always. If your DB trips whenever the geyser heats, stop resetting it and call.
A few drips while heating is normal expansion. A steady flow means a failing pressure valve, and it is wasting your water bill.
Water is already escaping above the board. This is the last warning before the ceiling comes down.
A failing element, sediment build-up, or a thermostat set wrong. Worth a look before winter.
Corrosion inside the tank. A geyser at this stage is usually near the end of its life.
Any of these and it's worth a call. Costs you nothing to have us look.
Call 075 014 4354A new geyser is a significant spend, so we do not reach for one first. We test the electrical and plumbing components and tell you honestly whether a repair will hold. Elements, thermostats and valves are all same-day jobs.
If it genuinely needs replacing, every install we do meets SANS 10254 and you get a PIRB Certificate of Compliance on the day — the document your insurer will ask for, not one that arrives next week.
| Element & thermostat | Replaced same day. The most common cause of no hot water and of tripping electrics. |
|---|---|
| Burst geyser | Emergency drain-down, removal and replacement, plus help with the insurance claim. |
| Valves | TP valves, vacuum breakers and pressure reducing valves — the usual cause of a dripping overflow pipe. |
| Solar & heat pump | Installation and servicing of solar geysers and heat pump systems. |
| Compliance | PIRB CoC issued on completion for every installation and major component replacement. |
By law a geyser replacement must be signed off by a registered plumber. Anyone who cannot issue you a CoC cannot legally do the work — and your insurer can decline the claim.
No queue, no "someone will be in touch". Here's the clock from the moment you dial.
A plumber picks up. Not a receptionist reading a script, not a callback form.
Before we've even left, you'll be talked through which valve to close. That part is free.
Typically inside the hour anywhere in Sandton, Randburg, Fourways and surrounds.
You see the problem, you hear the price, you say go. What you're quoted is what you pay.
Not an emergency? Same process — we'll book you a slot that suits you, usually the same or next day.

Geyser installs, COCs and certificates handled properly — the paperwork your insurer asks for.
Floors covered, mess taken with us. You shouldn't be able to tell we were there.
You don't pay for us to come and look. You pay for work you've agreed to.
Managing units? We deal with tenants directly, send one invoice, and keep you posted.
Geysers, drains, leaks and installations — the day-to-day of keeping houses running.
Geyser burst just after 9pm and the ceiling was already sagging. Called Prime Flow expecting a voicemail — someone answered, told me exactly which valve to close, and was at the house within the hour.
Two other plumbers wanted to lift my bathroom tiles to find a leak. Prime Flow traced it in about twenty minutes without breaking a single one. Quoted before starting and charged exactly that.
I manage a block of rentals and I've been through a lot of contractors. This is the first one where the tenants stopped phoning me to complain. On time, tidy, invoice comes through the same week.
Blocked main sewer line on a Sunday morning. Cleared it, then showed me the root that caused it and what to do about the tree. That's the bit other plumbers never bother with.
The emergency line is answered around the clock — weekends, public holidays, 2am — and it costs you nothing to get us out there. Close your main stopcock, then call.

We stay inside a tight radius on purpose — it's the only way to keep the 60-minute promise honest. Tap your suburb and we'll start your quote.
Just outside the list? Call anyway — if we can't get there fast enough to be useful, we'll say so.
Close the main water supply at your meter, switch the geyser breaker off at the DB board, then open a hot tap to drain what is left in the tank. Then phone us. Keep out of any room where the ceiling is sagging.
Most household policies cover geyser replacement. Insurers want the job done by a registered plumber with a compliance certificate, which is exactly what we issue. Photograph the damage before anything is cleaned up.
Age and what has failed. An element or thermostat on an otherwise sound geyser is a straightforward repair. A corroded or leaking tank cannot be repaired safely. We will tell you which one you are looking at before you commit to anything.
Nearly always a short circuit in a blown element or a failed thermostat allowing water contact. It is a same-day fix. Repeatedly resetting the trip is not safe.
A few drips while the geyser heats is normal expansion. A continuous flow means the pressure reducing valve or the temperature and pressure safety valve is failing, which wastes water and should be replaced.
Yes. Every geyser installation or major component replacement we do comes with a PIRB CoC you can submit directly to your insurer.
