Hi all,
Anyone help on what part I need to get to fit to a 340mm diameter cast iron downpipe that does not serve the main sewage run?
I'm told I need an ' Internal air inlet valve with rubber joiner'.
The cast iron pipe will be cut, sealed then boxed in internally in a conservatory.
Links to the parts to get would be helpful.
thanks
Robster
