Water Hammer in Steam Lines in Craighall
Loud banging in steam mains, sometimes with pipework movement. This page covers how we diagnose and repair it on steam systems in Craighall.
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 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. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

The usual causes are condensate accumulating in the main, failed or undersized traps, incorrect pipework gradient, sudden valve operation. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Trap survey along the affected main; Gradient and drip leg inspection; Valve operation review; Insulation and condensate load assessment. 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?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Craighall falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
