Converted to gas water heater OOPS

I had a new water heater plumbed by a licensed plumber and have some questions. He took a T fitting off the supply to the furnace and ran black pipe for about 4 feet then went to yellow flexible gase line that runs for about 6 feet down the side of the water tank to the gas regulator. It seems odd to me to have that much flex tubing. Most water heaters I have seen have black pipe to a union right next to the gas regulator. The use of the flexible tube leaves the pipe hanging and flopping around. I figured I could add a pipe hanger to solve this problem. Would using copper hanger on black pipe be OK? My guess is the lack of hanger was an oversight. Does this installation sound reasonable? Thanks

Gas hook-up

It sounds like poor workmanship, but if he put it in according to code where you live it should be o.k. Most copper hangers are made out of steel so that would not be a problem, the only thing that is different is the o.d. size. The right hanger for your pipe dosen't cost that much, your call, you can use a oversize copper hanger or get the right one for black pipe, both will work. Lots of luck.

Apparently code allows it here in Clifton, NJ. I am half tempted to buy some pipe and plumb it down to the regulator myself. There is a shut off before the flex and it shouldn't be much trouble to do it. There's really nothing wrong with it but it looks cheesy. I have a touch of OCD and need to have my mechanical room nice and neat. Thanks for the reply.

Some parts of the country require flex ran to gas appliances. This is usually earthquake areas, but you might check.

As to the length of the appliance connector, that is poor workmanship. There are code requirements for the max length of connectors. I haven't seen a 6 foot max for water heaters. There is 6 foot max for other appliances, but not a water heater.

You might want to look at some plastic hangers for the flex line.

But hey, you have a plan...redo what the plumber did...Good luck with your project.
