I haven’t been able to find anything in a search here of other postings or in diagrams that I have to verify venting these water heaters together is right.
Is it? I normally see separate vents for each
both identical 50 gal tanks
and yes the tpr drain lines are PVC, and even stamped ‘cold water only’
as long as it passes the backdraft test, ill be fine with it.
i would have called out the pvc cold water only issue. remember tpv turn on at 210 degrees.
I have never seen them combined in hundreds of two water heater homes around the Houston area. hard to believe this is allowed. Less cost to the builder. One less pipe, roof jack, and opening in roof.
