Steam Boiler Pressure Problems in Craighall North
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 Craighall North.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Craighall North is a high-value residential pocket of Rosebank, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. 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 Craighall North?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Craighall North falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
