Plumbing FAQ: Milky Water

Question: When I fill a container with hot water it is milky, but after a few minutes, the water in the container clears up. What causes this?

Answer: Complaints of discolored water are commonly blamed on water heaters and storage tanks, but in fact, it is a rare occurrence for today’s high quality glass lined tanks to have a lining failure significant enough to allow water to contact enough bare metal to discolor the contents of even a small tank. The most common cause of “rusty” water is a non-toxic iron reducing bacteria, scientifically termed Crenothrix, Leptothrix, and Gallionella. Water heaters and storage tanks usually require new anode rods as presence of iron bacteria contributes to premature anode failure.

The simplest treatment available is shock-chlorination of the system. This is a surface treatment, and often requires repeated trials in heavily infected systems. The chlorination of a system requires that you follow each step explicitly to avoid an un-treated portion of the piping system from reinfecting another part.
