Slow Constant Tapping ALL Night From Megaflow Tank
Posted: Fri Oct 25, 2019 7:13 am
There is a dull constant "tapping" sound coming from somewhere all night in the cupboard where the Megaflow tank is. It happens in the day and when the system is off. It seems to be coming from the pipe that goes up to the red expansion tank. I can feel it tapping/ light thud/drip when I hold the pipe. I "think" its coming from some strange big black valve looking thing (I have a photo) its got a black plastic knob and what looks like an Allen Key clip holder on it too with Allen key in it.
