Jus lightly tap on the top of the valve rod with your spoon ,just lightly It will stop. AND every time you are done casting and everything is cooled down. Clean out your pot,yes clean it. You wont believe how much crud is in the bottom. I have a bit driver on my cast table,just to take the valve rod out. Do this and you won't have a problem. And buy the way ,you will get a little drip. Nothing to worry about ,just clean the drip off before you pour. I put the die right up against the nipple,when held right,this works great. Jerry
