header tank overflow

[Darken72]

Hi guys in need of advice. Header overflow pipe dripping and access to the tank is difficult.
The good news is that i intend to have a combi fitted, but not till early next year. If i put shut off valve on cold water feed to the tank , maybe open it once a week. Will this be ok?
Worried about the overflow freezing in the coming months.

Small tank or big tank mate ?

The smaller tank above the big cold water tank. Access to the small tank in the loft is very difficult.

Yh if it's the small tank mate that will b fine to isolate , just make sure you isolate the mains going into the ballvalve and not the pipe coming from bottom of tank , you shouldn't really need to switch water back onto it unless you vent rads . Keep an eye on the water level for about a week when you shut it off and see if the level drops
