forgive the basic english of this post but not into plumbing!!!!
have a pressurised water system installed since house was built 3 yrs ago... and have an ACV tank in hotpress that shows a pressure of between 4 -5 bar. pump is down stairs in utility... cold water tank is external and not in attic..
nothing strange there ! over the last few days though everytime i turn on a tap or shower i can see & hear that the pressure in the tank drops until the pump kicks in, this has never happened before...
should i be worried or is there something i can do ??
