We're planning on moving our waste water exit pipe for sink/dishwaser/washing machine from one side of the kitchen to the other and though we could use a outside drain on the new side rather than the old drain.
However, I'm told that waste water cannot go into the same drain as this is used for rainwater from the house gutters and that we'd have to route the pipe back to the original drain.
Now while I don't doubt this is the case I really don't see why. Is there two completely separate drain systems coming from modern houses (built 1997), and these never mix or do the two drains meet half way down the garden?
