Mix stainless/brass or use brass w/lead? | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

I’m building a manifold with 2” brass pipe and tees for a single family home.

The first tap is 1.5” for fire suppression.

After the first tap code requires a solenoid valve.

I need to choose between a brass valve that had lead brass or a stainless valve.

I’m concerned about the lead and I’m concerned about corrosion from mixing the stainless and brass.

Which would be a wiser choice? Or is there a third option?

Thanks!
