I have to get a kitchen extractor and shower room extractor vented outside.
They are back to back to each other on the ground floor.
There are no external walls that lead to the outside.
I can run the ducting under the floorboards between the same joist (both extractors) all the way to the outside (approx 5m). Both extractors have one way valve on them.
My questions are;
1. Could I tee the ducting together with a Y shaped piece towards the end of the duct near the outside vent so it's just one vent on the outside wall?
2. Would I need additional one way valves put in the ducting? I cant see why, but years ago a building inspector insisted on it. My worry is that if the additional valves get obstructed/become faulty there will be no access to them under the floorboards.
3. The kitchen extractor will be more powerful than the shower. I have seen this once before and I noticed a marked drop in the efficiency of the shower fan if the kitchen fan was on. However, I have lived at my house for 10 years and never had both fans on at the same time whilst having shower. Even if it was once a year I can't really see this being a problem?
Thanks all.
