after one draw the red led flashes and wont let me use it again,if i turn the switch on the end off and then on again i can take one draw and then it goes back to flashing. Is this a fault that i can rectify or does it need sending back?

Sounds like either a bad battery or a bad atty. Try using another batt, then try a different atty.
