I had to buy a new brush the other day, so at the same time I thought i'd renew my hose for my CLX as it was snagged and the male rectus fitting was leaking slightly. Ive got the hose onto the brush, but for some reason I cant get the hose to fit onto the pushfit flow valve. I can get the old hose in and out of the valve so the valve isn't faulty, but the new hose doesn't seem to push in, it seams a bit more softer than the old hose? Any advice please, what am I doing wrong?!
