Boiler Repair in Pontypridd

Pontypridd's terraces climb the valley sides, and elevation is the thread running through most of the boiler work we do here. Mains pressure and flow fall as you go up, and properties high on the hillside can be running well below what a combi boiler needs to deliver hot water to more than one outlet. That shows up as a shower that fails when a tap is opened, which is a flow problem rather than a boiler fault — replacing the appliance does not fix it.

Where flow is genuinely limited, the honest answer is often a system boiler with a stored cylinder rather than a bigger combi. We would rather measure the incoming flow rate and tell you that than fit a larger boiler that cannot be fed. It is a short test and it settles the question.

Exposure is the other factor. Valley-side properties catch weather from every direction, and frozen condensate pipes are a routine winter call — the boiler locks out, the fault code looks serious, and the cause is an unlagged plastic pipe on an exposed wall. On sealed systems we also see expansion vessel failures presenting as pressure that will not hold, which people commonly mistake for a hidden leak. It usually is not one, and it is a much smaller job than chasing water that was never escaping into the house.
