Agreed ... and I also make a note of that as a concern because there are still issues with that ... even though I see it all the time ...

No matter how common it might be in an area, I think there is a valid concern with the long term integrity of venting where a tee is used at the base of a flue riser instead of an elbow, and there isn't an accessible cap with drainage provisions at the lowest point of the fitting (e.g. a small drain hole in the cap) ... maybe there was one.

Without it it seems to me there would be the potential for long term corrosion of the fitting from moisture just sitting in the base ... or possibly even clogging if the cap can't be accessed. But at least the hole in the side gives you a view of the fitting base to see if it is full of moisture or debris and needs to be cleaned out ...

Only 20%??

It's the other way around here...I see about 80%--older or newer houses--double-lugged neutrals, neutrals with ground wire, and double-tapped breakers or service entry lugs.

I bet I could make a pretty good living getting "rewards" from the electricians.
