Thanks for the video. I'm an HVAC contractor. First, concentric venting is most easily described as "a pipe within a pipe" it allows for a single penetration of a wall or roof instead of two pipes, each with their own Wall or roof penetrations. Next by my eye I would say that the concentric venting could be saved, and only the lower connection (exhaust) needs to be redone. There are tools available to take that joint apart and redo it thereby saving the concentric vent kit. Last, if you are in an area where the attic would experience temperatures below freezing, it is generally accepted practice to insulate the combustion venting. That wasn't done.
Out of curiosity why do you say the exhaust portion has to be redone? I presume all they would do is ensure adequate sealant is applied on the redo? Wouldn’t a far easier fix be just to caulk the joint at this point?
@@guoster4749 as I watched this video a year ago I can't remember all the minutiae, and I'm not going to re-watch the video I might miss something here. Having said that, when you have a bad connection on a PVC joint, you do not under any circumstances simply caulk the joint as you said, you need to redo the joint with proper techniques to make sure that it seals properly.
@@HeatGeek1 thanks for responding. Maybe caulk is the wrong substrate but I have seen a plumber simply add tru blue or the purple stuff to joints that aren’t sealed. Can you elaborate as to the technical reason why this won’t work?
@@guoster4749 okay "true blue" is a thread sealant. You have no pipe threads. The purple stuff you refer to is most likely PVC primer. It cleans the plastic surface and softens the plastic for better adhesion, but you do this before gluing not after. To use primer you have to establish a clean joint to start with. BTW, this is HVAC, not plumbing. While there is crossover, it is a different discipline.
I did HVAC for 2 years, became lead installer in 6 months. All the other leads I worked with never would glue the concentric kit for some reason, I always did and never understood why they didn't, maybe because gluing it was just a pain in the ass or something.
Very educational!

I've never heard of a combustion pipe freezing bad enough to stop the flow, but condensate drains on the other hand, big time freezers.

Excellent explanation. Do you charge a service call for these types of things?
Naw. Keep it simple. Just put a BUCKET under the leak! Haaaa
Nice , bet your very popular with the guys , but not with the lady's...😸✌️😘🍑☯️
