Vent pipe burst


There is a junction of 3 vent pipes coming together in my attic. The original installation had them sloping down to all meet at a low point. It appears that condensation has been settling at that point over the years (house is 20 yrs old). I live in northern vermont and the cold temp froze the pipe which burst.

Noticeable change for the better for toilet flushing, but am concerned about the original design. Should I try and rebuild this junction so that condensation runs back to the toilet / sink? Any thoughts on this?

"If it's broke... fix it"

Sounds like you have a good handle on things.
If it isn't already all PVC... plan to adapt to that first.
You'll probably find that a new roof boot will be in order too.

All vents should pitch downwards, 1/4" per foot, to drain any potential condensation.
