that's exactly how i do them toowhy do kitchen fitters assume they are bonafide competant plumbers? i mean that looks awful. i hate those rigs anyway, i got a 1.5 sink in my kitchen, i plumbed them up using two traps both joined in via a swept tee to one 40mm pipe.
now both sinks have a trap meaning no smells can eminate from either bowl. takes up a but more room under the sink but not that much to notice! and it will never leak!
