He said cut it off in the attic, then REPLACE with black ABS. He never said to vent it in the attic.

I'm sure it would make a difference if it was on an area of the roof that sees direct sunlight.

I wonder if simply painting it black would help?

Calling someone a moron does very little to help others with a sewer vent issue.

Advice,
Absolutely wrap the pipes in insulation as they run through the attic.

Any heat that might be coming through the lines due to the venting needs to be conserved until that heat and moisture get to the outlet of the pipe on the top of the roof to prevent any freezing.

Try to insure that you have no horizontal or near horizontal runs in non heated spaces. This practice just leads to frozen vent issues.


-----------------
I know that in North Dakota where my brother lives, he indicates that normally folks don't have vent freeze up issues, until there are multiple consecutive days of -25f consecutively for several days.

But even for those folks who do have freezing issues have all been able to solve their issues by using the copper pipe with the copper cross pipe at the top of the vent to prevent the pipe from falling into the vent system as well as to let the copper pipe breathe and bring the heated vent air through the stack and out the top of the vent.

So, unless there are multiple days of really cold weather, often combined with similar days of howling winds that really remove the heat - then lead to potential vent pipe freezing.

Take care

That is the easy way to fix the problem. A little flat black paint took care of it for me. Probably time to do it again since the paint doesn't stick to ABS that well and weather eventually takes it off.

I wasn't referring to any members here as a moron. I was referencing the maker of the video for creating an illegal and potential hazardous condition.

As far as being helpful, I hope post #4 of this thread along with everyone else was helpful to the OP.

I haven't seen where you said what diameter the vent pipe is when it exits the roof. Nor did I see any mention of where it is freezing. If it is icing up in the stack, at and above the roof-line quite often increasing the pipe diameter there will help.
Is there a possibility there is a dry drain trap somewhere in the building allowing a draft to be created in the vent system ?
I have had personal experience with all those situations in different houses.

This vent never freezes unless the electrical supply is off for an extended period of time.
