The answer to 'why is my faucet rusty water' is that it is likely due to corroded plumbing pipes or fittings. Over time, the metal components in your plumbing system can rust, causing discolored, reddish-brown water to come out of your faucets. This is a common issue, especially in older homes with galvanized steel or copper pipes.
Some common symptoms of rusty water include stained sinks and bathtubs, a metallic taste, and reduced water pressure. The good news is that there are several solutions, depending on the severity of the problem.
