Soweto · Priority
Boiler Losing Pressure in Soweto
System pressure falls and the boiler needs repeated topping up. This page covers how we diagnose and repair it on boilers in Soweto.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Large residential area with a high volume of electric geysers and growing heat pump uptake. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

FAQs
Frequently asked questions
What causes boiler losing pressure?
The usual causes are leak in the system pipework or radiators, failed expansion vessel, passing safety valve, heat exchanger leak. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Isolate sections and pressure test; Expansion vessel charge check; Inspect safety valve discharge for flow; Verify gauge against a calibrated instrument. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
Usually yes, for a short period, but efficiency and component life are both being lost while the fault persists.
Do you attend this fault in Soweto?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Domestic geyser repairs and element replacements handled same day where possible.
