Hello, I have a Vaillant Ecotec combi boiler. The flue pipe extension has started to leak at one of the joints. The internal plastic connection pipe appears to be intact. It still drips when there isn't a demand for the boiler.
I've attached some pictures and moved the joint strap to see. Can anybody please offer any advice and guidance.
Many thanks...
