Had buddy of mine show the IRC concerning the questions I had about water heater tp relief valve drainage. Thanks to all who answered my previous posts.
The question I have is about the change they made from the 2006 to the 2012 under P2803.6.1 Requirements for discharge pipe.
#5 stated in 2006 edition that the drain pipe will "Discharge to the floor, to an indirect waste receptor or to the outdoors. Where discharging to the outdoors in areas subject to freezing, discharge piping shall be first piped to an indirect waste receptor through an air gap located in a conditioned area.
#5 in the 2012 edition says the drain pipe will "Discharge to the floor, to the pan serving the water heater or storage tank, to a waste receptor or to the outdoors. "
Does anyone know whey the 'subject to freezing' was removed from the 2012 language? I am not a plumber, just trying to learn here. I assume they believe the air gap requirement in #2 would prevent any real issues.
