On a lot with two houses (detached from each other), one of them is having a problem where the water at all the fixtures is brown. Oddly, the other house does not have this problem. This is weird because there is only one water main coming into the house with brown water. I know the main goes into the house with brown water, and that the house with clear water is fed straight from the main trunk. Other parts of that trunk feed the house with brown water as well.
This is confusing me because the house with brown water has it at all the fixtures, suggesting it's coming from the main, but that same main also feeds the house with clear water.
Here is a plumbing diagram:
