Kitchen Waste Run - A or B

[HugeWesty]

Hi guys,

I am a DIY'er and looking for advice on a kitchen waste run. Which run is preferable A or B?

For A, from the washing machine/dishwasher waste, I get the runs to join the main flow asap.

For B, I have slightly longer runs from the appliances (with slight drop in each) before returning to the main flow.

Which is best, or does it really matter? Thanks

I would just use a dual outlet with one standpipe if it were me.

Doesn't really matter. As above, you can use one standpipe but two is fine if you have plenty of room.
