My soil stack is 5 metres away from the kitchen waste outlet. I'm going to connected a washing machine and a dish washer through a washing machin waste trap with two spigots connected. The kitchen waste will have its own trap and I'll put a tee fitting below it with a pipe run of 2metres for the appliances waste. My problem I don't know where the best place to fit aav? I've done a drawing with two locations can you recommend best practice?
