is this extraction fan fitted correctly?

[Brian C.]

The fan was fitted over the shower cubicle in November 2014. During the first year the firm that fitted it had to return 3 times as the unit was either not woking or making a terrible noise, each time there was a lot of water in the extraction tubing and the fan unit. The last time they came they fitted the insulation visible in the enclosed photos.

This week I took a look myself and once again found a lot of water in the pipe and in the unit. I am not by any means an expert but it seems to me that as the unit is fitted 14 inches lower than the outlet in the wall allowing steam and condensation to flow back towards the unit.

Am I right in thinking that the fan unit should be fitted higher than the outlet, this would then allow the water to flow down and out?

I hope the pictures are of some help and would be grateful for any guidance.

You are correct in your thinking.

the fan should be at the highest point.
if that's impossible for some reason, you can get these:
