The waste water in my bathroom basin is draining very slowly but there is no blockage in the waste pipes to the soil stack and this is not blocked as the bath waste run is flowing ok into it and out. What could be the problem.

Is it seperate to the bath waste?

Have you took apart the basin waste - right back to the stack?
yes they are seperate but go into the stack together. There's no blockage in the basin u-bend or any of the pipe and the stack is not blocked :confused: :confused:
