Unvented safety pipe to Hepvo

[ArtfulBodger]

Anyone used this? evidently Hepworth are now claiming it's all legal. I thought some individual BCO's were OK'ing it but not all.

How does it work anyway. Saying I'm coming off the tundish in 22mm, how does this connect to 32 or 40mm?

One more thing, how is it pronounced? hep vee oh?

This was posted elsewhere recently, if not here then screwfix, and supposedly been excepted by the BC. was posted in one of the trade organisation.

I can find NO BS number, which means I'm not looking in the right place or you can't use them.

I did my unvented a couple of months ago and it was just going through the final stages of acceptance then

As a manufacturer, I havent had anything official to say its approved, but like you, I have heard that it is passed.

It has been used by some installers so I have to assume that BC ok'd it, but it wouldnt be the first time that an unvented was installed without the proper procedures being used

Check with your local Building Control guys is the best advice to avoid hassle in future.

I use 'hepveeoh' when talking about it.
