Hi,
I have a Manrose in-line shower fan that exits through a roof space and through a pipe that goes up through a flashing plate in a pitched roof.
What do people find is the best option to stop back draughts happening? I’ve looked into a back draught shutter that fits on the fan spigot, but I understand these can be noisy, banging when the wind blows against them. At the moment there is just a weatherproof mushroom cap on top of the external pipe coming out of the roof.
What other options are there and what’s the best option?
Thanks in advance!
