Heater was replaced about 15 years ago with a tankless. It's about in the same vertical location, 2 floors down. I don't see how it's connected to that though.
Tankless using natural gas? Anything with open flame will be venting though that pipe seems really big for a tankless heater.
Yeah, I know where the tankless is venting. There's some PVC running from it to the outside wall, all in the same room. My guess is that pipe was leftover from the previous heater?
Probably. It’s much simpler to leave the vent than patch the penetration. I don’t know how often you can expect to need to replace the flange on a useless vent, but I suspect it’s not often enough to make it worth removing and patching.
mmm tasty old house water.
Could be a situation where they’re telling you they don’t want to do it by bidding it sky high.
It does to me too. They replaced the furnace in my old house like a year ago (2 miles down the road) and the labor was only $2k. It's a drop ceiling with the tiles already taken out of it so running the line seems like it should take about 7 minutes to me but maybe there's something I don't know. Going to have to call around a bit in the morning.
