Thanks for the advice. I'll start with lubricating the parts above ground and I was hoping I didn't have to work on the below ground part. How do you pull the inside part out of the tube?

I know I have a fair amount of iron/hardness and my garage faucet on hard water (a standard woodford frost free sillcock) is getting harder and harder to turn all the way off which is because when the water is left on but sprayer at the end of the hose is off then the iron settles in the parts on the inside of the faucet. I'm sure I'm going to have to figure out how to repack the guts on that faucet too unless there is a way to soak the parts in iron-out or something.

I suspect the hydrant by the pond also sets in water containing iron and probably is getting sludged up too.
