Hi everyone. In the process of planning some internal alterations. We're creating a downstairs WC and would like to make a utility space for washer and tumble dryer. Our only problem is getting them on an external wall for drains/ tumble vent. Drains I think I can deal with via a Saniflo that we're planning for the WC, but wonder about vent for tumble dryer. Don't want a condensing dryer but am happy to take a flexi vent pipe up the wall and across to the outside wall and box it in to make it look pretty. Is this a sensible thing to do, and is the run of 2-3 metres possible? I guess it will run vertically up to the ceiling (about 1.5 metres or so), then across horizontally for another 1.5 approx to outside wall.
