I am struggling to find a replacement 6 bar relief valve protecting an
under counter unvented water heater.

The unit was installed by tenants and is now dribbling!

I have tried releasing water to see if grit has lodged in the seating
without success.

There are no obvious manufacturer details and general Google searches do
not lead to a supplier of parts.

This must be an item fitted with all such heaters so somebody must supply
replacements.

any ideas?

Google provided several.

Yes. That's the job!

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