For example, flexible plastics are used in gaskets, refrigerator water lines, and harder plastics are used as pipes, faucet connectors and the like. Each plastic will also have a different reaction with chemicals and bacteria. Not all plastic is created equal. AND- color has no relation to how it performs. Colorants are often added by manufacturers.
How different are plumbing pipe sizes from the water distribution system?
Pipe surface area to water volume (SA:V) ratio is very large in buildings. This means that with narrow pipes (pipes with a small diameter), there is a lot more pipe surface area (sides of the pipe) used to hold the same volume of water. If there is anything wrong with the pipe (for example: metals leaching out of pipes, VOCs coming out of pipes, biofilm growing on pipe walls), the pipe will have a strong impact on the water. In the WATER DISTRIBUTION SYSTEM, larger pipes are used. These larger pipes can have much less impact on what is in BUILDING DRINKING WATER QUALITY.
