Insulation on outside taps can be a pain. Insulation gets dirty and often falls apart after a bit of time. My current insulating cover wont fit on with the hose connector so I need to screw/unscrew the hose fitting every time I use it in the winter. Are there any tap/insulation combinations that work well? I've seen one from arrow taps called 'Tap in a Box' which looks ideal but it is very expensive. Does anybody know whether these taps are good? They recommend to drain the water out of the tap in freezing conditions but I suspect this probably wouldn't normally be necessary on the side of a heated house in the UK.
