So I switched back to my microbore hose as I find it so much nicer to use when though I just can't get the same pressure through it to the jets. I've tried putting the de setting on my spring controller up to 70 to try and improve this but still not great. But what I've noticed is when I switch the tap on the pole hose off the pressure switch stops the pump before the de does. Does this mean I've got it set too high or is it ok to use like this?
