I have a stop connector on the microbore but whilst the pole is connected and the tap is off the pressure can be a bit much for that short bit of pole hose. Usually get caught out when i'm stood in the warm sunshine and a customer won't stop talking. The hose gets a bit supple and expands with the pressure. I always carry spares so it's easily fixed. Just a bit embarrassing when the water shoots down the front of my shorts.
do you have a pic of what you use ?
