How do you stop the thin flexi pipe/hose popping off the poly hose during watering? We have recently installed a new watering system on a timer for our garden and just about every time it turns on one of the flexi tube risers pop off the poly hose during watering and we get a streak of water shooting into the backyard. It’s getting very annoying having to fix them all the time. It’s not the same one each time either, it’s like a lucky dip 🤔 “which one will it be today?”
