Hi,
My builder installed under floor ducting to run from my downdraft hood to the garden, about 7 metres. Now we're at the point of installation I'm very concerned. He has used 100mm Square section pipe. The hood requires 150mm, and the run is long and has a couple of links to look up with the box.
Everything is telling me this is going to be a problem - is it best to link up the ducting and see how well it works, or just give up, curse the builder, and buy a recirculation module and...
Extractor ducting size - help please
