  • Did water heaters have 2-inch flues at one time?

    Seeing Hosh's photo make me wonder.

    I'd take an educated guess - but I'm unqualified.

        That's a 4"x3". Pretty sure at least. 2" would be tiny. I'll double check it soon. Now it's all 4".

          Is that a water pressure gauge installed on the pipe? I won't mention about the vent being reduced in diameter

            most likely a thermometer. the ones i use from raypak are a combination temperature and pressure with 2 needles.

            a gravity/ atmospheric vent water heater never came in 2''. they don't sell 2'' metallic vent pipe. single or double wall.

                  Yes, it's not bad if your water heaters need to vent.
