was fine until last week were it makes me awake most of the time. the boiler name is MYSON MIDAS but i cant find the manu. date. Every time somebody open and closed the tap (either hot or cold) it makes a noisy sound (like vibrating piping touching each other inside the boiler).I ask few friends and they said maybe the air pressure is low but not so sure. I am working night so its difficult to get sleep during the day because of noisy boiler. please can somebody help i dont any about boiler. please.
