Hi, our 3in1 boiling water tap occasionally has cold water come out of the vent behind the spout and also around the base, what do we do? Prev owner of the house installed it in 2017, we’ve only been here 18 months, changed the filters when it was indicated to do so.
I can hear what sounds like a tiny dripping sound inside the tap. It's been happening for a few days now, will leak from the vent hole maybe 3 times a day for a a few seconds
