I'm installing frostproof sillcocks as part of a larger project to
replace old galvanized with copper.
Do I need a dielectric union to connect copper to the chrome sillcocks'
threaded connection? I've noticed in various plumbing books similar
chromed fittings in bathroom fixtures connected directly to copper.
Thanks for your help!
with a dielectric nipple or union. Now allot of these are made of brass with
a chrome wrapper. most the time you put a MIP or Drop eared 90ty then a
brass nipple. The MIP is back in the wall a couple inches then use the right
size nipple to connect the Sillcock or what ever. The brass is supposed to
be a neutral metal.
But how do you know it is brass? I suppose, being a modern fixture it
would be made of a useful material that would ease installation. I
suppose I'll go with the copper female fitting I'm already using and
see if that passes inspection.
