Try keeping the underflor siphon wet - I imagine it is for water from floor-cleaning etc? Those siphons just tend to smell bad, if they dry up.
I remember working in an office-space where some old guy watered the floor-siphon in one of the bathrooms on a weekly basis to prevent it from smelling like shit.
