John Dirks Jr Posted August 28, 2010 Report Share Posted August 28, 2010 I was on a 1992 colonial today. The roof was relativly new but had fabricated lead boots. I could lift the cap off and see the PVC underneath. Never seen that before. Are these guys the "best practice" type or what?

mgbinspect Posted August 28, 2010 Report Share Posted August 28, 2010 Nice indeed. A similar product was touched upon within the last few weeks, if it's helpful. Quote Link to comment Share on other sites More sharing options...

Remember that, strictly speaking, the PVC isn't supposed to be left exposed to UV. A common problem with them is that squirrels will develop a taste for the lead. I rarely see them without little squirrel chew-marks on them. Every so often, I'll find them completey eaten up. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Inspectorjoe Posted August 28, 2010 Report Share Posted August 28, 2010 I've never seen it done like that. I occasionally see something like this: Click to Enlarge 26.36 KB In a cold climate the restriction can allow frost to build up and plug the opening.

The best I can figure is the vent is too small and the builder slipped the bigger piece over it to fool the muni inspector. Quote Link to comment Share on other sites More sharing options...
John Dirks Jr Posted August 28, 2010 Author Report Share Posted August 28, 2010 Whats the hooked vent for Joe? Maybe they were trying to provide separation between those two. Quote Link to comment Share on other sites More sharing options...
Inspectorjoe Posted August 28, 2010 Report Share Posted August 28, 2010 I don't recall, John. I doubt I figured it out. I just looked at the report and my only comment was that they are to close to the windows. I don't know of any prohibition on the return bend. I don't know if I ever saw another one on a stack vent. Maybe someone here knows why you would use it. Quote Link to comment Share on other sites More sharing options...

Inspectorjoe Posted August 28, 2010 Report Share Posted August 28, 2010 No, the furnace is in the basement and it's vented though the wall. Around here, Cat IV furnaces usually aren't used in attics because of the chance of the condensate freezing. When they are used, sometimes an insulated 'room' is built to enclose them.

robert1966 Posted September 4, 2010 Report Share Posted September 4, 2010 Yeal, most of the hooked or elbow vents I see here are for the Cat IV or high E furnace intakes and exhaust. Quote Link to comment Share on other sites More sharing options...
