Steam Boiler Pressure Problems in Alexandra
Pressure swings, safety valve lifting, or pressure that cannot be held under load. This page covers how we diagnose and repair it on steam systems in Alexandra.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Dense residential area with electric geysers and community hot water installations. 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 steam boiler pressure problems?
The usual causes are pressure switch out of calibration, modulating burner not staging correctly, carryover from high tds water, undersized steam header for demand. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Pressure switch calibration check; Burner modulation observation; Water TDS and alkalinity testing; PRV station inspection. 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 Alexandra?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Fast attendance from the nearby Sandton and Wynberg areas.
