#WATER HEATER OVERFLOW PIPE REQUIREMENTS CODE#
The T&P relief valve discharge piping was required to meet the code in effect at the time the new water and new T&P were installed - i.e., the discharge piping had to be rerouted to terminate in the same room or space as the water heater was located. This requirement goes back to maybe 2003 or 2006, I'd have to look it up to verify when it changed.

Q: On the TP relief value you recommend this be re-routed to the outside per industry standards.
