(Apologies if this has appeared twice, I've been having server probs.)
In our bathroom, the arrangement is - bath, then basin, then WC. The waste from the bath runs under the floor to join the soil pipe in a boxed in section in the corner. The waste from the basin runs between the cistern and the pan to join the soil pipe at a higher point. I'm about to change the WC for a close-coupled type, which means the basin waste will have to be re-routed. Is there any reason why I shouldn't take it from the basin trap down through the floor and T into the waste from the bath? I assume it would be better to use one of the connectors that produces a smooth curve rather than a right-angled T
TIA Steve
