Hi there. I have noticed a drip on the primary flow pipe going into the tank. Not sure what could be causing it. It seems to happen when the heating and hot water are off. Have attached a photo. It comes from the top and runs down the pipe.
No dripping in the tundish and we replenished the air bubble last week so shouldn't be that.
Thanks
