Hi guys I'm trying to help out a local windy who could do with a bit of luck. He's bought a backpack off ebay & the outlet pipe is just a length of pole hose. He already has what sound like (I haven't seen his gear) rectus fittings on a reel (female) & pole (male) which is what he uses when he plugs into a customer's outside tap. What he needs is a female connector on this length of pole hose which comes from the backpack, I can only assume (I don't have a backpack) that it also must be a water stop connector to prevent the unit from draining when disconnected? Two things spring to mind- can he replace this pole hose with a length of mini/microbore & just fit a normal rectus to that, or is there a water stop female rectus that fits pole hose size pipe? Any help here would be greatly appreciated, I will be viewing this back pack over the weekend & thus things might seem more obvious then.
