Hi
Our dishwasher is connected to the sink waste above the trap as per normal. I can see the logic in this, as the trap prevents drain smells getting to the dishwasher.
However, last week SWIMBO had poached haddock for dinner - and I can't abide the taste or smell of fish.
When the dish & plate were put in the dishwasher, every rinse cycle resulted in a horrid fishy pong coming up from the sink waste.
Any way round this apart from a separate waste?
