Why is my tap water yellow?

There are several reasons why your water might look yellow. Let us look at the most common of them:

  • Manganese and Iron. Tap water contains certain minerals such as manganese and iron. In the long run, these minerals form sediments, which settle at the bottom of the pipes. In case of changes in the water pressure, these sediments might surface and end up in the water flow. The pressure in the system might change if there is a water leak, pipes maintenance works, testing of fire hydrants,
  • Rust. Another reason why your water might have a yellow tint is rust. Rust is the most common problem tinting water yellow or even red or green. Iron sediments combining with water result in yellow tinge in your water. This is often the case when the pipes or faucets start corroding.

What causes well water to look yellow?

Well water quality often might be inferior to the water coming from the plumbing system. The quality of well water depends on the depth of the well and also its environment. The most common causes for yellow well water might be these or a combination of these factors:

  • Minerals. Well water can also contain dangerous amounts of manganese and other minerals. High concentration of this mineral might result in a metallic water taste or even tint surfaces and hands black.
  • Heavy rain. If the area where you live has experienced heavy rain, it might be that surface water is coming to the well. That might be dangerous, as it might bring organic material or decaying vegetation into your water.

The iron bacteria-infected water has an unpleasant smell, which often gets described as sewage, decaying vegetation. It is not dangerous for health but might cause plumbing problems.
  • Chemicals. Chemicals might be another reason why your water is yellow. This happens when the soil around the well is contaminated, and the contaminants end up in the well water.

It is an incredibly effective solution. It will purify and cleanse the water by removing contaminants which will result in better color, smell and taste. Reverse osmosis filters remove up to 98% of chemicals in water, nitrates, pesticides, various heavy metals, and bacteria. If you already have a RO system you can upgrade it with sediment filter.
  • Filter maintenance. Even if long-lasting, proper care of the filters is essential to ensure their top performance. Follow your manufacturer’s guidelines for your filter maintenance and cleaning. It is also a good idea to ask your plumber to do a regular check-up every few years.
