Steam Boiler Pressure Problems in Melville
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 Melville.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Older housing stock, guest houses and restaurants with small commercial hot water systems. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

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 Melville?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Older plumbing often needs valve and pressure control correction.
