Pressure and Flow Testing

(Local Authority) Building Control - (LA)BC. An unvented cylinder is a notifiable installation and as such either needs to be self certified by someone on an accredited installer scheme or they get building control to come and sign it off.

Ah, ok I see, so they are actually installing an unvented cylinder.
Correct

Just make sure they complete the benchmark and with their full name and contact details etc

The top box of the benchmark has been completed !but not by me! My phone number is an old one I last used years ago. The commissioned by name is unreadable. The Registered Operative ID Number box has not been filled in.
At the bottom of this part of the benchmark there is a space for a Building Registration Notification Number. In Scotland, do I need this bit?need one of these?i

and make sure the warranty is registered

Do I do this or is it up to the installer

and it is BC notified/self certified.

Don’t know what BC stands for or the ‘notified/self certified’ bit.

The full benchmark document should be completed properly. Yes a new unvented install, and open vented, should be notified to Local Authority Building Control ((LA)BC)

Do I do this or is it up to the installer

Depends - I as an installer would do it but that could be completed by the client, though I would have expected that to have been discussed with you by the installer

Don’t know what BC stands for or the ‘notified/self certified’ bit.

As above - the BC is your local authority building control.

Plumber says:
The Local Authority Building Control is not required in Scotland”.

OK - let me check, my understanding is that it is as the Building Regs in Scotland follow on from Part G in England but I can confirm easily.

 

[bolo 2]

Found it Madrab. Only needs LABC in Scotland, if 3 story’s or more or flats (SNIPEF).

 

[Madrab]

Thanks for that - There's been a lot of changes when it comes to building regs over the last few years and what is classed as notifiable and what is classed as permissible.

I always register my installs through GS so they automatically notify the install with the LABC, same with the boiler installs even though in Scotland they aren't compulsory notifiable either.

The saga continues! Discovered today that a discharge pipe which exits the wall at height, simply does a u-turn and at first sight looks as though it goes back into the wall 100mm or so below but doesn’t . In flagrant disregard of G3 regulations ( I’m told) It is simply cut and stops just before it touches the wall. It should, (I am again told) go all way down to ground level. What to do now?

Edit: “It should, (I am again told) go all way down to ground level”. Confirmed by manufacturer!

Are you sure, that pipe is not attached to a Pressure Release Valve (PRV)?

I’m not sure but the head of a large plumbing concern and the manufacturer’s rep were.

What cylinder is it? Make/model? Most manufacturers in the UK quote the building regs in their install docs as to how to terminate the D2.

The requirements for D2 termination is that it is it terminates in a safe location - high up terminations would need to be into a metal hopper or similar.

A return to the wall termination wouldn't be deemed safe any more IMO especially if the location is where anyone could be in the vicinity.

It follows the same standard as the others as far as termination of the D2. Return to the wall termination is no longer considered safe enough IMO, if anyone has the ability to be underneath it.
