Just wondering... Is it unusual to find a water supply main that is run through a furnace duct?

After I've won my suit against the contractor that hacked my furnace install, I am going to send a request for a refund from the state for the fee I paid for the inspector, who told me everything...

Do you have storm windows and/or double pane? Single pane?

It could be that the slightly curved pipe, leaving the furnace, is single wall that connects to a double wall, so it isn't a reducer after all.

I'm not a tech (yet), but am wondering if your furnace has a condensate trap on the exhaust vent, close to or inside the furnace. With the amount of condensate that is freezing on the roof, I would...

Done. That's how I was able to get my hands on the hacked concentric.

Thanks for the input.

This is Turtle.

You sure your looking at the furnace vent pipe and not the sewer drain vent pipe ? I'm lost looking at that home made kit.

It is hard to determine size of the pipes from the photos. Sorry I didn't post size of the pipes used in making up this concentric. The outer top pipe is 4", but then the guy necked it down to 3"...

It looks like the installer cut the concentric kit right in the middle, so he could lengthen the concentric, rather than lengthen the two pipes coming from the furnace.

Don't know why 3 and 4...

May we assume your crawl space has a dirt floor? If so, then, as the previous poster has suggested, you can hire just about anyone to spread out fairly heavy duty plastic sheeting. This is a very...

Koald,

Great critique. I suspect you and I are from the same epoch, but, "...only the Shadow knows."
Cheers!

Whatthehay?

So, how does one find, "...a true tech?" Do they have some identifying mark on their forehead or somewhere else?

You're right... I'm busted.
