Why does brown water come out of our pipes after we haven’t used the water for a couple of days? (Plumbing is only 3 years old).

-Jake

Jake, colored water (brown in your case) coming out of a faucet or tap is a result of high levels of dissolved or suspended corrosion by-products (e.g. rust or lime-like) caused by a reaction between the metal of the pipe and the water. When a solid forms and settles on the wall of the pipes, it’s called tuberculation. This happens mostly with galvanized and as water sits in this pipe when you’re not using it (even only a couple days) it becomes discolored. Since your plumbing is only three years old, it would seem to indicate that the water in your area may be chemically aggressive towards the metal your pipes are made out of. To deal with tuberculation, you could repipe (replace your pipes) or you could have the pipes cleaned out and epoxy lined (as is done with CuraFlo’s system) –this would take care of your immediate problem and prevent it from coming back.

Your water is probably safe to drink, but it can stain your laundry. It’s recommended that discolored water be tested so that you know what kind of contaminants you’re dealing with and if they’re safe to consume. You might also want to contact your local water supplier to get more information about the water in your area and if anyone else is experiencing what you are.
