" Well, let's meet Steve Bottazzi, a plumber."
" Hi Bob."
" I thought you'd be working up there cutting that vent pipe through. What's happened?"
" Well, we're positioning the vent because in this house here, we have two fronts for the house. We have a lakeside and we have a street side."
" And the pipe that comes through the roof isn't the prettiest thing."
" Right. So we're just trying to position it so it's not seen, trying to keep it out of sight."
" Under the- the edge of the"
" cheek wall"
" The cheek wall, good. Now how do you actually cut it through?"
" I'll take you inside and I'll show you."
" Okay."
" Alright Steve, so you're 24 inches off the cheek wall, but why are you gonna cut an oval."
" Because in order to put a round pipe through a pitch roof to have it come out straight, you've gotta cut an oval hole."
" There you go. Now let's go up on the roof and see how we make a weather tight."
" Okay, get that pipe out of the way Steve."
" Hi Larry."
" Hi Bob."
" Now what's that thing in your hand?"
" It's a roof shoe. It's designed to keep a piece of flashing that goes around the roof vent, so that water can't go down the pipe or enter the roof somehow."
" How do you install it?"
" Well, I've loosened up the nails in this roof shingles around the area of the pipe so that we can- we can locate it properly. Now what I'm gonna do is slide it up underneath and over the bottom force and Steve is gonna stick the pipe through and work it through slowly."
" So that rubber gasket makes it weather tight. You don't need any roofing cement?"
" No."
" And then you- you just put around with roofing nails?"
" So roofing nails at the top underneath- beneath the paper here."
" Right in to the plywood?"
" Right in to the plywood."
" [unk] hold it."
" Let's go right there. There we go."
" Okay."
" What about down here?"
" No. You don't put nails down here because the water, when it sheds up the roof, it's gonna hit the bottom in this metal and then back on to the roof and down and off."
" Right. That's all there is to it? You just put your"
" Basically I just have to replace the shingles around here and it's done."
" Great. Okay. Now why don't we go down to the basement and find out from Steve how he [unk] this plastic to the old cast iron. Anytime you're remodeling an older house, chances are you've got to deal with cast iron and plumbing pieces that wanna be connected to plastic pieces and how do you it, Steve?"
" Well we take a, it's called amana."
" Amana. This plastic joint piece is called amana."
" Right. And why do we need that thing?"
" It's a PVC amana but it changes from cast iron to PVC. "
" How'd you get it naturally?"
" We put oakum and lead."
" Okay. We just saw the lead."
" This is the oakum which has been around for centuries, and it's nothing more than jute, right?"
" Right. That's it."
" How do you fit it in?"
" Well we take it and we pack it. We put enough oakum in here that's why you've got about half an inch room for lead."
" So you're gonna wind around about three or four times?"
" Yes. Depending on the fitting, some it takes more"
" Alright, so now you have to fill it up with melted or molten lead, how will you keep the lead from dripping out in a horizontal situation like this?"
" We have what's called a joint runner."
" A joint runner."
" A joint runner which goes over the manoff or"
" Now this is a temporary thing, right?"
" Right, it comes off after it's been poured."
" Yes."
" You take the joint runner over the manoff."
" Clamp it shut."
" Make sure it's nice and tight."
" And what, that'll keep the lead from running out and you can pour it in through the top?"
" Through the top, exactly."
" Wonderful."
" So we take that, we take a little piece of oakum. Hold down here."
" Now let's talk about the fun part when you get to melt the lead, you've already got, oh this is, wait a minute"
" Yes, I've got some leftover from another joint I had done."
" I see and they're hard and dried up again."
" Yes."
" So how do you gonna melt it?"
" Well, I'm gonna take the torch and we'll just melt the whole thing. It will take a few minutes because the lead is still cold."
" Alright, it will only stay melted for a little while so here we go and you pour it right in up the top."
" Oh no as soon as it gets to the top and starts pouring out"
" There you go."
" and it's full."
" It's full."
" Now, how long do we have to wait before it's done."
" Well, it will take, let it cool like a half an hour because right now we've soften the [unk] plastic"
" Sure."
" And before we can pack that pack the lead right into the oakum. After 30 minutes Bob, we can take that"
" Yes."
" Let's see what kind of joint we have."
" The lead is hardened up."
" It looks good."
" So that's it?"
" And we pack it so that just in case, we won't have any problem with leaking afterwards."
" Okay, so you have to push it back in still farther."
