long kitchen waste run

[caz26]

Dear All,

I'm looking at a near 7 metre run to waste pipe outside for new kitchen. Is this feasible with 40mm waste and using an anti-vac trap. It would only be for a single bowl sink and dishwasher.

Should I take any other precautions? Not really any other option as waste pipe is to rear of house and sink now at front.

Thanks,

Caz

Do it in 50 mm and be prepared for a blockage in the future so make sure you can access the pipe to clean out.
