Dielectric fitting?

[Sawyer]

Garn requires dielectric fittings between the iron pipe connected to the Garn and copper fittings attached to that pipe. If later in the copper piping system a single black iron tee or several tees are connected together, to create a manifold, are introduced, must these fittings also be protected by dielectric fittings?

No, they would not need dielectric fittings.

I don't think the Garn actually does, either. From my conversations with their regional distributor, as long as there is 6+ feet of iron pipe between the Garn and any yellow metal (copper, bronze, brass), they're happy. It's usually a non-issue, since the majority of installations involve piping off the back, then all the way to the front using iron, before connecting to anything else.

Thanks Joe, as you said, by the time you pipe forward you are definately more than 6' of pipe.
