But, uh, those, uh, the inside of that valve he got, it looked like it, uh, it's pretty stopped up with, you know, mineral deposits. So that's probably what's got both of them. Um, but I just want to let you know where we're at. I'll get, uh, I'll get them ordered and get them in here. I don't think they're supposed to have birds in the airport. Yeah, I'm not sure what the, uh, TSA policy is on that. What's up, dude? She said, well, it ain't never leaked. That make a 3/8 to a 1/2-inch flare, the 3/8 copper? I know I had what's called getting one at, uh, McKenzie. Yeah, that had to be 3/8 copper with 1/2-inch. You can't put a 1/2-inch, uh, flare nut on a 3/8 line and try to flare it out big enough to where the hole— oh, you can't put a 1/2 or nothing. You can put one of 3/8 hole and a 1/2-inch thread.

Um, it was a lot— be a lot Better and a lot easier if he can put the coil on in the furnace than had to put a slab coil on the duct on it, huh? Still going to have to fix the duct regardless. Yeah, you going to have to take that old one out and fix that piece. Probably got to do it with water anyway, hopefully. I don't know how much room is under, uh, the house on— where's it? Under Pigley, I guess, where that house is doing. Yeah, got to have some decent room under it if you got a slab coil on That's true. Room right there beside— well, you know what, if it had decent room, they might would have put the furnace all the way under there. And it might be why the furnace is sitting in the— some reason they went slab. Get your fund out. Heck, heck, heck!
