hi all , i have a shower fan/light installed and although it seem to be working as it should i'm getting water dripping through where the steam should be going?? it is running into the loft space and out thru the side gable end with a grill on it with the 3 flaps. last week the vent tube was full of water and i have now angled it up from the light to the fan ( mid tube) and then down to the grill at wall. any suggestions as to why its happening. thanks
