Unvented pressure release into sink waste pipe - smelly

Complete lash-up.
I would imagine the installer doesn’t hold a G3 ticket.

OK, this is what he did for us :-

Pressurised the heating system
Replaced our vented system with an unvented cylinder

Apart from the smell all seems to be working well without issue.

Just a thought - was we supposed to receive a certificate of some kind ?

Yes, the cylinder needs to be registered with Building Control and you should receive a compliance certificate. It also needs registering with the manufacturer for the warranty

ok, registered for warranty but didnt get any BC certificate. Looks like another plumber on the scrap heap ffs. I guess I should get a proper G3 plumber in to check it all over and get it registered ?

However, is not true that if the plumber is G3 then BC is not required ?

Just checked Gas Safe register. He is on there and he is ticked against all of the following :-

+ Building Regulations
+ Combustion performance gas analysis
+ Domestic Cookers/hobs
+ Gas Fire
+ Gas Boiler
+ Gas installation pipework
+ Domestic flued range cookers
+ Unvented Hot Water storage Cylinders
+ Vented hot water storage cylinders
+ Gas Water heaters

So I guess all is cool and I should simply get him back to fix the smelly pipework / tundish.

No. His G3 registration allows him to self-certify with Building Control without a BC inspector coming to assess the work. The installation still needs to be registered
