Over the past few months, I have been getting a stale smell, like wet-musty towels, in the bathroom. I have used bleach and caustic soda in all obvious orifices and the smell goes away for a week or so but then it comes back.
The smell seems to be coming from the plug hole in the hand basin so I removed the S-bend attached to the plug hole. There was some black damp / mould inside the fitting but this was only a very small amount.
I attach a photo of the pipes on the adjacent outside wall - I guess these are the pipes for the toilet outflow / stack and the shower tray waste and the hand basin waste-->

I read comments on this site about flaps ? Could there be faulty "flaps" somewhere causing this smell if the sewage smell could maybe be coming up the shared stack ?

Is it possible to undo the waste (plug hole) in the shower tray once a shower tray is installed ?
