Hi, my hot water system (50L Dux Proflo) has an ECV (expansion control valve) that was fitted in 2019, ever since then it drips pretty much after every shower or usage of the hot water, now normally this wouldn't be an issue but the system is in an interior cupboard which means the constant addition of moisture to the air is helping mould grow in the cupboard and give the cupboard that hot musty smell. The pipe drips into an overflow pan and then into a pipe that takes the water outside but its just the fact the water is there and the unit puts off so much heat into the cupboard I think it must start to evaporate some of the water. I wish I could lift the system to pipe it directly into the drain and not the pan but its such a tight fit I would need someone to disconnect the whole system to do that, The place I live at has high water pressure so should I look at turning the non return isolating valve down a bit to reduce the amount of water going into the system and hopefully reduce the frequency of the dripping? would that help at all? thanks in advance
