The first I knew about it was when I saw Just Drains on site yesterday afternoon with the drain clearing equipment. The stink was so bad I couldn't have much of a conversation with Gary about it. So I am afraid I am in the dark. I am sure that RMG are aware of the health repercussions and are dealing with it.
Update at 10:45, Just drains are on site working on the problem now. If you have any suggestions then pop round and speak to them direct.
