I have always got my flow valves from Gardiner's up to now, but I have found them to fall apart too easily.
When holding it in your hand whilst cleaning windows the red end caps can easily loosen and pop out because of the hose being pulled by gravity as you lift the pole up and down whilst cleaning.
Also my most recent nuance with them is you only have to get your pole hose caught or snagged once whilst walking and the red cap and internal metal retaining clip can fly out. And in my experience once the retaining clip flys out, if you find it, the valve is never the same again.
I called up Gardiner's today to let them know that the valve i purchased broke on the first job ( hose got caught whilst walking up steps ) but they said i was at fault because I yanked the hose.
For the record I try to look after my gear and appreciate the fragile nature of these flow valves, so don't just go yanking my hose everywhere... I digress...
Anyway, I need a more robust flow valve, any ideas or recommendations?
