sink waste connect to bath waste?

[Vass]

Any reason why I can't connect my wash basin waste to the Bath waste before it goes out through the wall?

[Peter Taylor]

If you're not worried about the basin water coming up through the bath plughole, and not concerned about going against Building Regulations and all good advice, then no.

Do you mean 'can you connect both wastes to the same waste pipe' before it goes out through the wall, or connect one directly to the other?

Never happened on ours, seems pretty unlikely.

Is it against building regs?

Our old house had the wastes combined. You may find that you get get gurgling from the other was, this can be sorted with an air admittance trap.

yes connect both to the pipe that goes out the wall into the hopper outside

Thats how mine is and I've never had any problems - I assume its standard practice.
