When it freezes like it will this week night after night after night it will still freeze up,you have water in the system somewhere ie the pump the joins and the bends in tubing the fitting going into the reel the list goes on.
If you do get it going the hose will be so stiff once you get it off the reel you won’t get it back on it lol.
Well, plugged my £15 radiator in last night and guess what ?
None of the above happened.
Just cleaned my own windows as a test run. No issues whatsoever.
Still wouldn't want to be out working today/tomorrow and I don't need to be. Pavements are still iced up and the wind chill doing my own windows was enough , I've got to tend to my wood burner anyway
