Cold Water Checks
Never allow cisterns to overfill. Water in overflow pipes can freeze, causing the cistern to spill over the sides.
In a long cold spell, open the loft hatch occasionaiiy to let in warmth from the house.
If you leave the house for short periods, keep the central heating turned on, turned down to the minimum. For long periods, drain the system by closing the main stopcock and opening all the taps. When water stops runnng, open the drain cock near the stopcock.
