WH vent pipe

I never saw this before - it looks like a dryer hose connected to the wh. All the references I have indicate a single walled metal pipe to be used as a gas appliance vent connector. Aside from that fact that it’s not screwed into the collar, this one doesn’t seem right. Any thoughts?

Yeah, this one was not double-walled and the ends were cut eliminating any labeling that might signify an approved material. I thought so. Thanks for the replies.

Hi Bill,

Looks like Dura Connect, single wall is fine until it goes through a ceiling. Was there double wall going through the attic?

I see these installations here regularly at newer homes, no problem.

Except for the missing connectors. . .

I think that was mentioned “Senior Zinsco”----:lol:

My point being - the connector is absolutely necessary at the B-vent transition. If it doesn’t have the proper connector, well, then it’s improper :mrgreen:

I cannot see the ceiling in the picture, but your (invisible observations) would be correct if the proper connector(s) is-are missing—

By the way…what’s with NO Zinsco Pictures for the LONGest time?..I truly MISS THEM “Mr. Santa Zinsco Clarita”—Cookin Baby…Cookin—:ack!:

You still in the “Inspection Business”?—:lol:

OK…I’d be happy to see at least one Federal Pacific doing a little cookin—:twisted:–:lol:…work with me ole buddy—O:)

Agreed. (Don’t overlook the insulation too close to the draft hood and vent pipe.)

Good call Dale - Dura Connect - a new one for me. Jeff, you got it right too - no connector at top or bottom. So: proper vent connector with improper connections at the wh and b vent. I love this bb!
Much appreciated guys.

Hi Bill…I was just looking at my link…you know, I think that is rated as Type-B…but I am not positive…it says one inch clearance to combustibles as “B”…but I do not know the rating of the material without doing a little more digging.

Jeff Pope may know whether it’s “B” rated or not even being single wall.

I know it DOES NOT bend all that easy (i’ve tried it)…really some tough material.

Oh…and I forgot about the “Twist Lock Connectors” which was cut from the portion you have posted at the draft hood.

From Dura Connect website:

I just came across this at an inspection yesterday. This doesn’t look right to me, what do you guys think?
