Question about Plumbing
Can you adjust the stem on a ball valve so that it does not drip after being closed for the winter
Probably need to re-pack the stem with stem packing thread

It depends not the valve, if it a gate valve ( the kind that screw in as you turn the handle) then you can usually use a crescent wrench and tighten the bonnet that holds it together. If it is a quarter turn ball valve ( the kind with a lever handle) you came remove the handle on some of them and tighten the nut but not all can do this, last resort is replacement. There is a newer product out there that the do it youreselfer can use very easily it's called SharkBite and HomeDepote carries it.

Unfortunately, ball valves cannot be adjusted. The ball valve works by having a polished ball, which has a hole drilled through it, swivel on an axis. In one direction, the water flows through the hole, in the other, the water is blocked.
If a ball valve leaks, it's likely caused by the teflon packing surrounding and holding the ball in place has been scratched or damaged.
The worse news is that unless you can find the EXACT model and size of the existing ball valve, you won't be able to replace those packings. ((Best case scenario is to buy and exact match, steal the packings from the new one, and dismantle the old one to rebuild it with the new parts))
The worst case scenario, of course is having to replace the existing ball valve with a different one.
