About a month ago I was out in the garden and saw the drain was overflowed with water. There were lots of leaves etc and I cleared it
and all seemed to be fine. And on Monday, I saw the same thing again but no leaves!!! And now we have a drain smell in the house. On the opposite end of the house weirdly.
Are there any things I can do before having someone in to look at it? Or has it gone past that stage?
