The hot water coming out of our tub faucet turns brown after a few seconds (obviously rust in the water). It eventually gets better but not enough to be clear. We hardly use this tub but have been attentive to run the water daily since we thought it was from lack of use. The problem remains and we cannot use the tub/jacuzzi. Why is the water rusty? The hot water in the sinks and shower is clear. This bathroom was remodeled 5 years ago. Thanks for any suggestion you may have to solve the problem.
