Have your water tested if it has an unusual taste or smell or if it is brown or reddish. You can then have it treated to improve quality.

You can install a residential water treatment system to reduce the concentration of iron in water to an acceptable level. Be sure to install a certified system conforming to NSF/ANSI standards and follow the manufacturer’s maintenance recommendations.
