non return valve fitted in the main steam line is chattering, as i have previously asked this question on 08-11-2002(by the name of zaib), and tom has rightly guessed that the boiler is running in battrey with an other boiler. NEXT I WANT TO ASK HOW THE CHATTERING OF THE VALVE CAN BE PREVENTED?
THANKING VERY MUCH FOR VALUEABLE COMMENTS..
