Google provided several.

Yes. That's the job!

I'm now curious to know what search terms you used?

"6 bar relief valve" copied from your posting!

Hmm...

I tried *pressure relief valve* and then filtered for 6 bar.

Then various flavours of the above.

Under counter heater manufacturers were found but seemed unprepared to
offer spares of this type.

Anyway problem potentially solved, subject to original plumbers comment
that *they always leak in high water pressure areas*.

Thanks to all who helped.

regards
