Smell from a little-used bathroom
Water in the traps. No acid. The stair = the manager.
A bidet or a waste shut for weeks lets the trap dry: a drain smell indoors.
A) 1–2 L of water in every little-used waste. That is often enough. B) No acids; if biofilm remains after hair, open the slow-drain page. C) Stack or several flats: who to call, not a gel.
What to do now (€ 0)
- 1–2 L of water in the bidet, shower, washing machine, basin. Trap seals if they sit empty for days.
Minimal DIY
Household moves, not a building site. A stick and a deodoriser do not fill a dry trap and do not repair the sewer.
