Foul small under kitchen sink
Hi, I have a terriable small coming from under my kitchen sink ( in the cupboards) I have cleaned out all the pipes which came to nothing as there was no blockages. Today I had a plumber out but he couldn't find anything just told me that there were no blockages ( I already knew that and I don't know much about plumbing) the smell seems to appear when its raining don't seem to smell anything when its dry, I have tried all the drain cleaners, soda's but again it still there. Any help to what it could be.. please be simply I am a women and me and plumbing don't seem to get on well lol
