Replace iron fittings with brass?

Hi,

In my house, I have a rusted iron tee fitting in the potable water supply (to the kitchen). The iron fitting is 1/2 in and has one end going to a sillcock (chrome-plated brass???), the other two connected to brass (or maybe copper?) adapters to flared copper pipe.

My first inclination would be to just replace the tee with a brass tee, but I recently found out that brass contains significant amounts of lead. I think that this would be a legal option, but is this what would be suggested? I'm starting to think that this concern about lead might be moot because my nice new Moen kitchen faucet has lead it it, and probably contributes much more to the contamination of the water? Is it "standard practice" to use brass fittings or are they avoided now?

Thanks,

Nathan

Brass pipe and fittings have been used for centuries and NO ONE has died from them. Do NOT be terrorized by scaremongers who are pushing their own agendas. I use brass nipples and fittings whenever they are appropriate.
