were you using the fastcolour fastlusent flaming orange if so i have had the same problem with the water coming through and thought it was the gun or compressor but when i did another shell the same thing happened but it only happens with the orange paint and no other colours so have put the fault with the paint not the equipment so dont be to hard on yourself but it is anoying as hell as there seems to be no reason for it to happen, next time you try, try and avoid using the orange and see if you get any problems
