What causes red / brown water?
Discoloration of water normally is caused by naturally occurring minerals (primarily iron and manganese) that are flowing with the water. Normally what happens is the minerals, being heavier than water, settle in the bottom of the water pipelines, especially during winter months when water usage is low. Then, when the water flow and pressure through the water pipes increases (due to irrigation, construction, etc.) it stirs up the minerals and they flow with the water and out the faucet. That’s why, to help avoid the issue, we “flush out” the water systems.
