Yellow water is tap water that exhibits a yellow discoloration, typically caused by rust, mineral deposits, organic matter, or municipal plumbing maintenance. It is a common indicator of plumbing issues.
In more detail
In real estate, discovering yellow water during a home walkthrough or inspection can indicate underlying plumbing or well issues. Common causes include rusting galvanized steel pipes within the home, iron buildup in a private well, or water main flushing by the local utility. While yellow water is often harmless and caused by minerals like iron, it can stain fixtures and laundry. Buyers should determine the source of the discoloration to avoid costly pipe replacement or well filtration repairs.
