Furnace Leaking Water

[ItsNemo]

Hey, quick double check here...5 year old high efficiency furnace, PVC exhaust venting fully up to code, noticed a tiny drip of water coming from a glue joint at an elbow on the exhaust this morning.

Any concerns with just replacing the elbow and re-gluing everything? Or is this a sign of a bigger problem?

Checked the vent itself isn't plugged, slope is all good (back towards furnace), no issues prior, I know there's usually condensation in the exhaust...so just a matter of a joint that wasn't well sealed and finally started dripping? Or anything else to check before I replace with the to code pipe/glueing?

I would wiggle it around and see if it is loose. If not then I would more likely just try to clean it real good and then try and work some cement into the gap and see if it seals up.

If not then you have the plan

Ended up just calling the HVAC company who installed it today...as I was digging into it, I noticed a couple scorched wires up near the burner where the flame sensor/ignitor are. Given there might be some other minor issues with the furnace and how hard parts are to get for HVAC stuff and that stores are all closed up here right now (can only do curb side at home depot), I'll just pay someone else to sort out the problems.

Also, PVC is not allowed as a venting material in Canada. Speak to your dealer about that as well.

What do they use to vent 90plus furnaces up there?

Most likely PP (polypropylene)

Uh yeah it is...? There's PVC rated for the application that's used pretty much everywhere in high efficiency applications.
