Hi

I cannot see any bleed at all on the hot potable circuit. There is an auto bleeder on the central heating circuit (I had to replace that too this weekend), but seemingly not one on the domestic water. Even of there were, my question is about bleeding air from the expansion vessel (the water side of the mebrane) because the expansion vessel is in effect on a spu at the highest point, I cannot see how bleeding from lower down can hel anyway.

I suspect over time the water will dissolve and come out that way.
