Before inserting the valve back into the trumpet, put enough valve oil on the valve so that that the surface is wet, but not dripping.
Insert the valve into the trumpet, and screw in the top clockwise.
Be sure to grasp the top of the valve and twist until a clicking sound is heard and the valve locks in place to ensure that the trumpet is ready for playing.
