The waste outlet on a new sink is lower than the old one, and fitting a standard p-trap would leave it lower than the existing pipework (so no natural run-off).
A solution would be a shallow trap (eg shower trap) which would then go into a running trap in the pipework, but I gather running traps are prohibited by most authorities. Any reason why? It would save re-routing pipework through the wall etc
Thanks
