Part L Pressure Testing - how does that work with trickle vents, I assume they must be closed during the test ? from my experience they are not the most sturdy/air tight bits of kit.
Trickle Vent Extractor Fan - is there such a thing, be easier that drilling a huge hole through the wall. I want to control, on a timer when a room is vented for a tenant - who's room is constantly damp from all the clothes drying, despite asking for a top window to be left open, it never is, trapping all the moisture.
