Crawling under the house to deal with the well pump has led me to take a look at the water heater. I was going to drain it because I doubt the previous owners of the house ever did. However, the plastic valve is stuck closed! I'm afraid to wail on it for fear of breaking it. Would spraying inside the spigot with WD40 help or would that just eat away the plastic? Any suggestions? Note that the valve is probably stuck closed by iron and mineral deposits--in fact I can see that dreaded orange tinge on the ball valve inside the spigot.
