1. Why is my water “cloudy” or “milky” looking?

Water in the distribution system is under pressure and air sometimes dissolves in the water within the pressurized lines; the quality of the water is not affected by the entrained air. Once released at the faucet, the dissolved air gives water a “cloudy” or “milky” appearance; in fact, many faucets have an aeration feature built in.

Just let the water stand in an open container for a few seconds, the air in the water will disperse to the atmosphere.

2. Why is my water “rusty”?

Rusty looking water is due to iron oxides from water lines that are constructed of cast iron or galvanized steel. When water stands in the mains, fire hydrants, or in a customer’s galvanized service or internal lines, it will naturally dissolve the iron and you can expect periods of discolored water.

Rusty water at the cold water tap at the first draw in the morning is probably from your plumbing. If only the hot water is rusty, the source is probably your hot water system. If your cold water suddenly becomes rusty, there may be construction in the area, fire hydrant flushing, or fire hydrant use in the area. These episodes are temporary and will easily be cleared up on their own.

Note: Over 99% of our distribution mainlines are cement lined and do not contribute rust color into the system.
