We have a problem with a drain smell in our cloakroom, which is fitted with a shower. I realise that it is possible to fit a non-return valve to the outflow, but access would be very difficult. Then I came across an Australian non-return valve which might fit in the shower drain:

And I also found "floor drain duckbill check valves" - but no associated web page.
Has anyone come across these, or anything similar?
There are three that work on the same principle:

Many thanks. My problem with that type of fitting is lack of access - which is why I wondered about the Australian non-return valve.
To answer other points made - I don't think the trap is defective, it's not very old, but it definitely isn't used much. But it has always been slightly smelly - and my wife has a very delicate nose!
