Spot the crack 👀
This hairline crack in the secondary heat exchanger assembly was allowing water to leak out of the heat exchanger and on to parts of the boiler that it shouldn’t be touching; causing corrosion. Left untreated, this can cause the boiler to rot through, leading to a dead boiler! Fortunately we spotted this on a routine service and a temporary repair was carried out, with a new assembly to be fitted soon.
Featuring my war wound from managing to drill in to my hand whilst servicing the AGA at this property - not sure how deep, but deep enough to bleed like a water fountain 🩸😬
