Leaking around joint of PVC pipes in attic
I had a high efficiency furnace installed in my garage 5 years ago (it's the only place the furnace could be placed). It's a pain and wish I'd never had it installed. Currently I have buckets collecting the condensation that is oozing out around the joints in the PVC pipes in my attic. The installer is coming out today to fix it but I'm concerned that it will just be a quick patch job and not corrected. My question is, if the installer just slaps on more sealant over the old, now wet, sealant, will it really seal? And even if the old sealant is removed, the pipe is still going to be wet and I don't see how a proper seal can be achieved. In my mind the two pipes need to be taken apart and sealant put in around the joint - but that's not going to happen. Is it possible this was never done right in the first place? Will I have to have the pipes resealed every couple years to prevent this from recurring?
