I did the backs of a house this week, and just before packing up I was standing fiddling with one of the clamps, water still flowing as I couldn’t be bothered to bend down and pinch the pipe right at that moment.
Anyway, fiddling took longer than I thought, and when I looked up, the water jets had been squirting directly onto the clean washing next door, (in quite an artistic pattern too). Mainly towels and t-shirts.
Their back door was open, so I quickly packed up and left before someone came out.
Good job it’s hot weather, hopefully they dried before anyone noticed.
