    Default TPRV drain pipe on Tankless water heater

    Tankless gas water heaters are becoming more popular in my area and I am wondering if the termination height standards for the TPRV pipe are the same?

    Yes, the termination height if a factor of the most restrictive of all the following: 1) the code (not more than 6" above the floor, ground or receptor); 2) the manufacturer of the T&P valve (at least 6" above the floor, ground, or receptor); and 3) the manufacturer of the tankless water heater (does not matter what they say, between 1) and 2) you are left at 6" above exterior grade ).
