Boiler Losing Pressure in Cedar Hills
System pressure falls and the boiler needs repeated topping up. This page covers how we diagnose and repair it on boilers in Cedar Hills.
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 Hills sits within the Fourways belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. 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 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 Hills?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Cedar Hills visits carry heat pump and geyser spares together, since both are commonly installed on the same property.
