OldMeg we have been having serious discussions about hoses as ours does 'surprise' watering and needs to be replaced. Our gardener/friend is very keen to instigate a system similar to that which you describe. He has only just embarked on his scheme and I am already bewildered. The hoses, clips, connections and sprayers, which he has purchased on our behalf and been repaid with our money, are a rainbow of colours and there does not seem to be a sensible system although I am assured that there is. I think I have just retired from watering!
