Hi,
Just had an inspector not pass a water heater because the cold water inlet has a 3/4" threaded brass ball valve on a 3/4" galvanized pipe stub out of the wall. The house is plumbed in Galv. He stated that a dielectric union was required in between the galv. & the brass valve. 2010 California plumbing code does say "dielectric unions shall be used at all points of connection where there is a dissimilarity of metals". So I guess it's letter of the law but has anyone ever done this or heard of anyone requiring this? And I'd love to know a what he wants to do at every brass hose bib & brass angle stop!?
Thanks
