When I turned the screw, water started spraying out.
Literal
I [subject-が] screw [object-を] turn-[when-と] water [subject-が] spew-come.
The conjunction と marks immediate temporal/conditional consequence — 'when [clause], [result].' ネジを回す ('to turn a screw') with と chains to the next clause. 吹き出す ('to spurt, to gush, to start spraying') is a compound: 吹く ('to blow') + 出す ('to come out'). 来る (てきた form) adds the directional 'came out toward [me].'
