I guess I'm wondering if there's a way to use the existing roof exhaust and run some sort of non corrosive liner up it (in conjunction with a new hi E water tank). This way it seems like you would save the higher costs of coring and installing a side PVC vent on your house.
At least it seems cheaper in my mind...
