    I read somewhere that flex connectors on heaters were advised on the west coast for seismic reasons. Is this required by code and is it normal to use a flex connector between the building pipe and the drip leg/black pipe nipples at heater? I would like to go black pipe all the way but i am trying to determine what is required and/or customary.

    Thanks!

    You're in earthquake country. We use gas flex for water heaters. The drip leg is good.

    thanks. I have currently gone pipe all the way to a tankless and to the furnace. See attached images. Would you suggest modifying these and putting flex connectors in on both?
