I have recently bought a property dated 1950's everything was fine but every now and then especially since the weather has got colder the upstairs toilet smell's like a sewage drain.
I know you may think its just the toilet but the smell seems to be coming up into the toilet from the drain at the base of the house, I have cleaned the drain when I first moved in and also flushed it through as best I could but the smell keeps returning.
Im a DIY novice I like to try my hand at things but plumbing scares me, I would rather build an extention than mess around with plumbing, I dont have alot of cash at the moment so need a cheap fix or solution.
Many thanks
