So i use the Pure Freedom Pole Flow Control Valve, and a few weeks ago i had a kink in the hose which was spewing water out. It took me ages and was a right pain to get the O clip off to then put some new hose on without any kinks in. I ended up slightly damaging the control valve where the O clips go onto just because i was really rough with it as i was struggling to get the clip off. Is there an easy or straight forward to take O clips off? For some reason whenever i do it, it's a right pain!
