: I have a 1 year old two story house. We have 2 natural gas hot water heaters. One hot water heater provides water upstairs, two full baths; and the other provides hot water down stairs, 1.5 baths. The upstairs is not used much. The hot water in the sinks upstairs is milky white. The hot wate in the bath tubs upstairs is fine. : Shortly after moving in, we did find one comode upstairs hooked up to the hot water (made for a nice warm seat at night). The plumber corrected this. Could something he did to correct this cause the water to be milky white?: The milky look to the water is not air bubbles. The discoloration is so intense, you cant see through it (i.e. when you run the hot water and cup your hands under the faucet, you cant see the bottom of your hands).
