Am in a relatively new house and have been messing about in the loft. I have two separate cold water tanks joined by a connector at the bottom of the tanks.
There were no lids and the tanks poorly insulated. I've fashioned some lids (being unable to find exact fits anywhere) out of marine ply, covered with plastic flysheet sandwiching some celotex type insulation in there to insulate the lid.
Anyway the water in one tank looked a little "stagnant" (small amount of white stuff on the surface. I've had a little read and it looks as though perhaps not plumbed quite right. The feeds for the hot water tank and the cold water to the bath and also the ballvalve where water enters are on the same tank. (The overflow is on the "stagnant" tank, with none on the other tank (I imagined a situation where the bottom connector froze and I would then be left with a single tank without an overflow, but I probably worry too much).
Should I be looking to have the ballvalve moved to the other tank? Should I be looking to leave the existing ballvalve and add another ballvalve to the second tank? Is the overflow arrangement standard or should each tank have separate arrangements?
Sorry for the all the questions - I really appreciate the help.
