Hey thanks for that reply...It has probably been like that since the house was built but now is working correctly thanks to you :D . Albeit I have a sore head after cracking it on a joist :!:
I have 2 extractor fans in the house I have just moved into..one in the bathroom and the other in the en suite. Both are vented thru the ceilings. The bathroom extracts well but the ensuite actually blows air into the room when switched on which i assume it should not do. Removing the grill...
