Boiler Losing Pressure in Alexandra
System pressure falls and the boiler needs repeated topping up. This page covers how we diagnose and repair it on boilers in Alexandra.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Dense residential area with electric geysers and community hot water installations. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

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.
