Outdoor ice, drainage and winter

01

Drainage decides whether it works at all

An ice machine produces meltwater continuously and has to send it somewhere with a reliable fall. In a masonry island the drain often ends up run to a gravel soakaway or a short stub under the structure, and both silt up. When the drain backs up the bin floods, the ice fuses into a block, and the machine reports a fault that has nothing to do with its refrigeration.

Where a pump is fitted instead, the pump and its reservoir need to be reachable. An outdoor pump behind an immovable stone panel is a repair that costs more in masonry than in parts.

Well water outdoors, and then winter

Where the house is on its own well, the outdoor machine gets the same sediment and hardness as the kitchen one, and typically with less filtration in front of it. Small cubes and a sticking harvest follow. And when the season ends, water left anywhere in the machine or the buried supply run will not survive a Sudbury January.

Twenty minutes in October

• Shut off the supply at the house, not at the island
• Drain the buried run, the reservoir and the machine itself
• Clear the bin, clean it and leave the lid or door propped open
• Clear the drain path and confirm it is empty rather than merely quiet
• Clean the condenser while it is accessible and dry
