I've got 3 on 3 different poles and two won't turn off.
The least used one is fitted to an slx 35 and used once or twice a week and works ok albeit a bit snatchy
The others are on a pole with a flocked brush for leaded glass and a stiff for all other glass, my every day poles.
The univalves on these won't turn off unless I fold the hose over, to stop the pressure and then pull as directed. This then works.
So a pressure issue I thought, although it doesn't explain why it works on the longest pole.
I've recalibrated the pump to try and lessen the pressure but it's made no difference.
Is this a sign of wear?
Thought I would ask on here before I try to get hold of Stephen
TIA
