Expansion vessel on unvented system is hissing

[CNelson]

An engineer came to take a look at it today and heard the noise. The expansion tank is a bit too big for the system, it is currently 18L. It needs a smaller one.

thanks for the responses.

Rubbish! I've never heard of issues with a slightly (which yours is) oversized expansion vessel. Undersized, yes. Oversized, never!

Bet the vessel pressure was incorrectly set!

It does not need a smaller one !!!! You can not over size an expansion vessel, trust me. It is the charge pressure that is wrong.

If you want to go over 100 Deg C you may need a bit more pressure, but not on a domestic, OP will be back next week under another name, Title "My Safety Valve is leaking water"

Nelson, do you get the distinct impression that your man has just opened a can of snakes, how long did it take him to come to the conclusion it was too big ???
