I've been mostly stuck on the furnace and water heaters for a couple years now so I've gotten somewhat rusty and pretty out of touch with proper practices.

Anyway, just wanting to leave a thank you note.
Never a problem. That's the biggest reason that most of us are here. TO LEARN!

When I started out, I pulled a vacuum through my manifold, watched the needle on the low side, listened to the vacuum pump and thought I was doing things properly.

My evacuation procedure is quite a lot different today, and I'm still not sure I'm doing things correctly.
