How do I stop my Sadia H Water storage tank vibrating?

Question

when I use hot water the pressurized tank sometimes vibrates quite badly I have checked all the pipework and it is all clipped so I don't think it is a loose pipe. the system is about 18 months old

Answer 1

They make a device called a water hammer arrester for a  permanent solution, install a water hammer arrester as close to the source of the problem as possible. This includes a body of air which is isolated and sealed from contact with water so that it remains effective ongoing.
