I have a tankless water heater. We had to run the vents 35' to the side of the house where there was no porch. The rise is better than 1/4" per 10'... And we used 3" PVC... However, because it has been below zero the PVC is freezing up on the inside of the pipe... Last night we had no hot water so I took a gallon of hot water and slowly poured it down the exhaust vent and that did the trick...
I figure as long as its -30 I might have to do that every other day? Any other ideas?
