The fire wont go out!!!!

This probably isn’t helpful as it has been so long but...ages ago I had this problem and I put a sprinkler down and that fixed it after a long period of time. I couldn’t do the pool tactic which someone said above as I had a basement underneath. Sadly I have this issue again and it isn’t going but you could try what I said above. Hope this helps.


(I wrote this ages ago but forgot to post it so I will try post it again to see if it could help anyone)?
