Has anything changed recently with respect to the material for a T & P relief valve extension pipe? I have come across a few water heaters with Schedule 40 PVC being used on a 4 year old house, and new water heater installation by Sears. Did I miss the memo?

I have also seen no drip leg provided at the gas line to the water heater and furnaces, just an elbow turned into the gas valves. Did I miss something there too?

Nothing has changed. PVC is not allowed for TPR discharge. Sediment traps are required by some codes and most manufacturers, but not all.
