Week 1; Turn off the outdoor water supply at the stop valve and drain the pipe between the tap and the stop tap.
Insulate outdoor taps with proprietary lagging
Empty hosepipes, wind them up and store under cover.
If the cold has made the hose too rigid to coil easily, try running warm water over/through it.
Week 42>; Commence clearing away dead/dying annual bedding and fallen leaves as necessary.
Week 44>; Prepare / protect outdoor containers containing less than hardy plants.
Week 52; Make certain that all exposed water pipes (including drained ones) and taps are lagged, as severe cold can 'creep' along metal pipes and cause problems indoors.
A stop valve should he situated somewhere along the spur line connecting the indoor mains and outside tap, enabling the pipe to be emptied by means of a drain plug.
