Why is My Tap Water Yellow?- 3 Reasons at a Glance

why is my tap water yellow

Problems with the quality of tap water have a relatively large impact on people's normal life and work, because water quality safety is closely related to our health. Generally, the yellow water out of faucet is caused by the following 3 reasons.

1. Not using water for a long time will cause yellow water coming out of faucet.

When tap water is not used for a long time, it may react with the pipe wall and the metal cavity of the faucet to form colored metal ions. When you turn on the faucet, the tap water flows out together with the metal ions, resulting in yellow water. At the same time, the water turns yellow after the water is cut off. During the process of resuming the water supply after the water is cut off, some attached impurities in the pipeline will be washed into the pipeline by the strong water flow, resulting in a temporary yellowish water phenomenon in the tap water.

2. Corrosion of water supply pipes will cause yellow water out of tap.

Some old household water supply pipes use cast iron pipes, galvanized pipes, and other pipes. After a long time of use, the metal inner wall is easy to gradually corrode. When tap water stays in the old pipeline for a long time, the metal on the inner wall of the pipeline will form colored metal ions under the action of a chemical reaction and dissolve in the water, commonly known as "rusty water". Rust, sediment deposits, and microorganisms in the water pipes will be brought into the water, forming secondary pollution of tap water. When the faucet is turned on, the water washes away the rust, which may cause the water to turn yellow. This phenomenon is particularly prominent in the morning and after the water is cut off. Corrosion of water supply pipes is the main reason that causes your question "why is my tap water yellow"!

3. City construction project will cause yellow water out of faucet.

Why is my water yellow all of a sudden?---Caused by the city construction project. After the water supply pipeline project shuts off, reopening the valve may cause the flow rate of the water to change transiently, and the phenomenon of yellow water will appear in a short time. Water pipe repairs, valve replacements, pipeline renovations, and other construction processes require temporary water suspension. When the water supply was restored, due to sudden changes in water pressure and flow rate, some attachments on the inner wall of the pipe were washed away by the strong water flow, causing the tap water to turn yellow for a short time; Sediment, when the water supply valve is opened to resume water flow, the sediment will be impacted by the water flow, which may cause the water to be yellow and dizzy. In general, if you put more water in this situation, it will return to normal soon. If this is the case for a long time, the water supply line may burst, or leak or the source water may be polluted.

How to Deal With Yellow Water Coming out of Faucet?

If the water turns yellow suddenly, we give priority to turning on the tap for a period of time to remove the sediment and rust. Under normal circumstances, the water quality can return to normal in a short time. If the water in your home is yellow or cloudy for a period of time, we suggest that you take action from the following aspects.

1. Clean the water pipes

If the color of the water flowing out is relatively light, and this situation does not occur very frequently, it can be solved by cleaning the water pipe. If dark rusty water flows out frequently, or there are even obvious rust blocks or water leakage, it means that the pipe is seriously corroded. At this time, it is recommended to replace the pipe directly.

2. Stainless steel water pipes are recommended

In the home improvement industry, plastic pipes are currently the most commonly used, such as common PPR pipes and PVC pipes are all plastic pipes. Plastic water pipes generally have disadvantages such as easy aging, easy bursting, and breeding of bacteria, which will cause serious damage to water quality, and greatly reduce people's health index, and the carcinogenic rate will be high in the future. Stainless steel pipes are corrosion-resistant, high-strength, resistant to ground subsidence and earthquakes, and have a service life of at least 70 years, which is more economical than plastic pipes and other pipes. After using stainless steel pipes at home, it will have a good effect on the water quality of the water pipes. It can well solve your worries on yellow water coming out of faucet! However, due to the high price of stainless steel pipes and the difficulty in construction and installation, it is difficult for ordinary household users to accept.

3. Install the pre-filter like under kitchen sink water filter.

If the faucet is aging, the water will turn yellow because of the rust. At the same time, the city's water supply pipes are old and long, and the rust, sediment, and other impurities in the pipes will not only cause yellow water and water equipment control failure. If in this situation, we recommend installing a pre filter to filter out impurities in the water through the first protection to protect the water quality in the home.

Whole house pre-filter is generally installed at the entrance of the main pipe to restore the quality of the incoming water to the factory standard of tap water. It is a reliable impurity filtering device, which can filter impurities such as sediment, rust, floating objects, and other impurities visible to the naked eye, greatly extending the service life of subsequent equipment. Here our SimPure V7 under kitchen sink water filter is really good for solving your problem of why is my water yellow!
