I asked not so long back about my gas dryer getting fitted, mainly, do i need a 5" exhaust to go with my 4" tube, and was told,(can't actually find it) the post, to get a fitter as the question i asked, probarbly reflected my knowledge on the subject, that was not the case, i went and got a 4" exhaust, was told i need a five" so, got a refund, plumber turns up with same 4" and fits it, soon to get signed off, is this right
5" exhaust= flue through wall (ok, not a flue)
4" pipe= tube/flexie, from dryer to exhaust
5" exhaust= flue through wall (ok, not a flue)
4" pipe= tube/flexie, from dryer to exhaust
