    Can I just extend the existing pipe for my hot water heater relief valve to extend it to be within 6in of floor?

    Would adding the additional pipe and coupler still meet code, or do I have to replace the entire vertical pipe? The valve starts at the top of the heater and has one 90 degree elbow with 2 or so feet of pipe directed at the floor, it needs to be 20 inches longer.

    A coupling would be fine to extend the relief line.
