Basin Trap

[carver]

Hi
I have just purchased a chrome trap for my new bathroom sink. Although a '32mm' trap the chrome waste pipe supplied is actually 30mm and appears too small to make a seal in standard 32mm push fit fittings.
How do I connect this ??
Also this supplied chrome pipe is about 300mm long, not long enough to go all the way through my external cavity wall. where should I aim to make the connection ??
Thanks

buy it at Bodgit & Quit did we ?
to connect to white or grey waste you will need a compression joint not a push fit

Thanks.
As the chrome pipe will not go all the way through the wall, where should I make the join to the grey pipe. I am concerned about having this inside the cavity but it will appear ugly on the indside of the room ?
Thanks
