    I've put in an inline extractor fan in the cavity loft in the bathroom just above the shower.The steam from the shower does not get sucked in and fills the room.I replaced the fan with a more powerfull fan and its still the same.Im at my wits end with this thing as the walls are dripping wet.Im now thinking it could be the position of the vent ,but surely above the shower is the best position.

    Where does it vent out too. Also in line fans usually have back draft flaps. If the fan put on the wrong way the fins dont open. Just double check.

    Well not a cheap 30 quid one then. Some have little dials to alter the fan speed check that is set higher. Also double check all connecttions of the duct work. Check the fan is suitable for the diameter and length of ducting you have.

    Please show us some photos of the ducting and the external vent.

    It sounds like it is obstructed

    Silly question but would the fan need direct feed from mains as currently it has the feed from the light ,it has this feed,like i said i bought the wrong model and direct feed means its constantly on.The ducting is actually smaller than than the fan outlet as the previous fan had 4 inch outlet,this is 6 inch which is currently connected via 6 to 4 inch adapter,hope that makes sense

    The external vent please.

    If you take off that ceiling mushroom, does it suck better?

    Will take a pic tommorow too dark,but there is a proper vent there.There is hardly any suction there with and without it.Ive put a tissue there and i have to put it in the ducting to see the suction.If i put my hand to seal it again hardly any suction.

    With a bit more investigating found out that the bach draft flap was installed the wrong way,so it was actually closing when it should have been opening.Glad it was that simple but fuming with the guy that installed it for me.Thanks for your input guys.
