Boiler Losing Pressure in Cedar Lakes
System pressure falls and the boiler needs repeated topping up. This page covers how we diagnose and repair it on boilers in Cedar Lakes.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Cedar Lakes is a high-value residential pocket of Fourways, 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.

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 Cedar Lakes?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Cedar Lakes falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
