Why is the water that keeps flowing in the water pipe yellow?

The reason why the water that keeps flowing in the water pipe is yellow:

1. It may be caused by rust on the inner wall of the pipeline.

2. The water source is not cleaned or seriously polluted.

3. There is yellow sand entering, and the precipitation is incomplete. Cause: pipeline aging or chemical reaction.

"Because the underground cast iron pipe network has been used for a long time, the phenomenon that tap water turns yellow does not rule out that it is related to the aging of the underground pipe network. Another reason is that there are two kinds of water sources in Hohhot, one is groundwater and the other is Yellow River water. The water we drink now is basically a mixture of these two kinds of water. " The water quality of these two kinds of water is up to standard, but the production process and temperature are different. When they are combined, they will react, causing rust to fall off and tap water to turn yellow.

Pipeline category:

"Concealed engineering" is a very important issue. If the water pipe leaks and bursts, it will bring irreparable consequences. In the past, the pipes used for water supply were mainly cast iron pipes. Sand cast iron pipes are mainly used outdoors, and galvanized cast iron pipes are used indoors. However, after several years of use, it is easy to produce a lot of rust and scale, breed bacteria and seriously endanger human health.

The state stipulates that from June 1 2000 onwards, sand casting process pipe fittings and cold galvanized cast iron pipes will be eliminated, the use of hot galvanized cast iron pipes will be gradually restricted, and aluminum-plastic composite pipes and new plastic pipes will be popularized. The state also stipulates that all kinds of pipes and fittings involved in drinking water pipelines must be approved by the health department before they can be sold.
