Loft bathroom creates bad smell.

[Andwarr]

We have a loft bathroom, and whenever we use any of the facilities... flush, sink or shower, it creates a bad smell around the rest of the house. We have a Saniflo Pro, but have had it checked by a plumber and there is no fault there. We've also had it checked for leaks. I didn't think the upstairs pipework was even linked to the downstairs, which is adding to my confusion.

We have all the correct pipes in each trap in the house, and none of them are dry.

Confused... hoping there's something I can do, if anyone has any ideas please?

Much obliged.

Where does the saniflo discharge to. If there was no fault there would be no smell so your plumber hasn't checked the entire installation properly or is wrong.

Saniflo new? have you had new changes in the home?
