hi all
has anyone suffered from flow/pressure problems while using a sureflo?
ran out some micro bore today (about 30m), ran pump, connected pole - nothing! o actually a very very small trickle!!
went back to check for kinks, none! pump was running and then stopped as it had got upto pressure.
went back to pole - nothing! repeated the above 3-4 times before pulling all the hose back to van, then it started to work!!!!!?

i am thinking air lock or something?
