Plumbing in Llanishen

Llanishen mixes interwar semis with substantial postwar development, so we see two fairly distinct sets of systems here. The older houses tend to have original pipework and steel radiators that have been through decades of alteration, which is where sludge and lost inhibitor become the story. The later properties are more standardised, and there the common thread is boilers fitted in the same period now arriving at end of life together.

Because north Cardiff's water is soft, none of this is about limescale. An annual service here earns its place by checking system water condition, expansion vessel charge and the condensate route rather than by descaling anything. The condensate route matters more than people expect — where it runs externally, it is the single most common cause of a boiler locking out in a cold snap.

Bathroom work in Llanishen is generally less constrained than in the terraces: there is usually more floor depth to achieve fall for a level-access shower, and more freedom about where a WC can sit. It still comes down to where the soil stack is and which way the joists run, which is why we look at the floor properly before promising anything.

That is a frozen condensate pipe. Where the condensate runs outside it freezes overnight and clears as the day warms. Lagging or re-routing it is inexpensive and prevents the whole problem.

Often, yes. Properties here generally have more floor depth to work with than the inner-city terraces, but it still depends on which way the joists run and where the soil stack sits. We look at the floor before promising it.

Combustion and flue integrity, seals, controls and safety devices, system pressure, expansion vessel charge, inhibitor level and the condensate route — with the readings recorded. Descaling is not the point of it here.
