Thank you, I didn't realise this was meant to be common knowledge, bought one at the shop today and it had FA directions on what i'm meant to do with all the parts.Great hints on this channel for novice that dosent know even the basics. Thank you.if it bursts out often it is a good idea to cut the end of hose to get down to clean unstretched hose tip again. this may be harder/tighter to refit so just put end tip of hose in a small tub of hot water for a short time. it will warm up and this allows you to easily stretch/loosen the hose onto the adaptor for a more secure fitting. hose will cool down and shrink around fitting. tips my dad showed me.
