We have one that is Stainless Steel, and has multiple ports. The government has required the removal of lead in brass, so the low lead brass or bronze units will turn green like an old copper penny. The green patina causes the valve to seize up and lock down. I don’t recommend anything made of low lead brass. Just more un-needed government regulations that don’t make anything safer and increases the cost to the consumers. But Stainless Steel is really the good only option available.
