I have a floor to ceiling cupboard in my new kitchen which will house a tumble-dryer, atop the washing machine. Behind this (on the other side of a stud wall) I have installed a downstairs shower/wc/basin room. Above the 'cupboard' (in the ceiling cavity) I have already installed a 4" flexible vent-hose which passes through a 9" wall and goes up through the garage roof to a roof vent, complete with mushroom cap!
What I need to do is vent the bathroom (via an extractor fan) and join the vent from the tumble-dryer onto the same trunking/ductwork but I'm concerned that the duct from the dryer should have some form of non-return valve built into it, either in the trunking, hose, branch connector or even as part of the bathroom extractor.... wherever really!
Is anyone aware of a product on the market that will allow me to do this in whatever method that can be adopted from the description above?
Any one tackled two appliances to one vent like this before?
Thanks for any pointers,
