Is the univalve fixable ?

[scottish cleaning service]

What I do know is that the green PU hose sold by Gardiners gets more stretchy with warm water. I can feel it. I have a roll of red Exceed hose which I'm going to swap over to if it's long enough for my current pole and see how that goes.

I bought 100m of exceed red pu hose and never had a problem.

It actually works the other way around.? The plunger closes the exit of the valve so water pressure would be forcing the plunger onto its seat.

OIC- makes sense
