    Default This gas line can't be up to code... right?




    Obviously, it needs straps, but I just can't imagine that having this gas line running in front of the tank to the furnace is a) a good idea and b) code.

    Then again, I am a mere GC and not a plumber!

    Thanks in advance for advising me.

    I can't tell you about code, but from a practical standpoint, I sure isn't what I'd do. When the water heater needs replacing, you will have to disconnect the furnace pipe. I can't see in the picture where the line come from, but I'd go up, across, and down to the furnace. This probably could be done with ready cut and threaded pieces of pipe plus a few fittings. On a different topic, what is the hose connected to the water heater drain valve for? Many of us remove the original valve and replace it with a ball valve. Works better than the el cheapos they put on at the factory. I would not leave a hose running across the floor unless I was draining the tank.

    Code doesn't care about location.

    It does need earthquake strapping on the tank.

    It's a bit tricky replacing a heater when the pipes are like that, but we see that sometimes.
    It can take a bit more time.

    Yep, our plumber was draining the tank to change it out. And yeah, if there was ever a tank that needs straps this is it!

    I thought it was poor design at the very least and I guess I'm used to seeing flex lines...

    Thanks, all! This forum is so helpful!

    You can't have obstructions in front of the tank. The tank needs to be able to be replaced without having to remove all of that pipe. However, not a lot of inspectors are going to make a fuss over it either.

    There is nothing against code about it, and it is done whenever the gas line is NOT located in the space between the two devices, but, WHY does it need seismic strapping? Are you in an earthquake zone? A more common method, however, would have been to install the valve on the pipe at the tee and extend a 36" flexible line across the front of the heater to the furnace gas inlet.

    The tank is quickly removable by virtue of the two flex connectors. I actually have a similar connection on my WH. The gas valve is on the rights side wall at top of tank height. A flex connects over to the Watts 210 valve which replaces the TP on top, then hard pipe goes to the left, down to a drip leg, and another flex to the gas valve.
    I think WA state does have seismic regulations.

    I don't see what the big deal is...

    Sure it's not the most ideal or practical, but you don't replace the hot water heater every six months do you?

    It was put together with wrenches and can be taken apart with wrenches too.
    It might take 10 more minutes to disconnect the flex to the furnace and twist that whole chunk w/ the tee, but it's still not a big deal.

    Probably to get within range of the short gas flex they had for the furnace.
