Hi,
I'm new and have tried searching for the answer but it seems my problem is too basic!
We noticed one of the the down pipes for the guttering was growing a kind of mould, due to a constant supply of water running down it (and a few plants growing in the gutter!).
I've traced the problem to the overflow for a small cold water tank in the loft. It seems that the tank is warped and the water level is now just over the overflow pipe.
Firstly what is this small tank for? The water in there seemed 'old' and had sediment in the tank (which was easily stirred up just by experimenting with the ball c*ck). I run all the water in the house and couldnt make the tank empty as it all came from the huugae cold water tank next to it. (this tank is about the same size as a toilet cystern)
Secondly how to I go about adjusting the ball c*ck level so that it no longer 'leaks'.
I noticed on this site everyone says 'find the outside water supply tap before touching anything'. What am I look for here, a small man hole cover?
Any help is much appreciated!!!
