I'm replacing my well pump and air pressure tank. I'm a little leary, in that the joints are rusty. Any tips to loosen them? I do have some pics but don't know how to post them here.

Most people here swear by PB Blaster and not WD-40. I would think either will work, and a little heat via a propane torch or heat gun would help too.

Thats because PB is a penetrant and WD is for moisture displacement and very lite lubrication.
 
WD-40 is great stuff for what it is intended for, but it's not a good penetrating oil. I don't know what it is that makes PB Blaster so much better than other penetrating oils, but it is fantastic stuff for rust and corrosion on tight fittings.
