One of the loos in our rented house is smelling intermittently, but getting more frequent, of drains!
It's a rented house and blocked drains is about the only thing we're actually responsible for.
The loo is not blocked, it's flushing well but just smelly. It's just not getting better on its own.
What can I do now that will mean I'm not going to have to get the plumber in?
