Not sure what kind of water lines you have. Antifreeze was left once for two years in my trailer. Flushed the lines once after and there was no antifreeze taste or smell.

Plastic is not 100% "impermeable" and can most certainly absorb/transfer odor or taste from one liquid to the next.
SEE HERE"Does plastic absorb odors?
Plastic containers are very commonly used to store food. Many times, the food leaves an unpleasant or strong odor which does not go even after washing and drying the container. This is because plastic has a tendency to absorb the odor which then becomes very difficult to get rid of.
Also know, does plastic hold smell?
Plastic is also often a large non-polar molecule. The fragrance can absorb into the plastic and come back out later. Water and isopropyl alcohol are both polar and won't dissolve the fragrance very well. Soak that thing in detergent for a while to get rid of the smell.
Similarly, why can you smell through plastic? Smell is physical contact between molecules and sensory cells in your nose. If you smell something through a wrapper or bag, yes, the odoriferous molecules are penetrating through the plastic. Many plastics are porous to oxygen, which can seep in (it's called mass transfer) and spoil the contents.
""PEX" IS a type of "plastic" and is no exception to the party..
SEE HERE"Odor or aftertaste caused by improper storage, installation or from municipal or groundwater (well water) water contamination. PEX, like many other plastics (i.e. polypropylene jugs used for milk and juice) may absorb odors. If improperly stored or installed next to a source of odor, PEX may transfer it (albeit, in small amounts) to water, resulting in unpleasant smell or aftertaste.
A number of residents living in areas with increased industrial activities (drilling, manufacturing) have also reported gasoline-like or chemical odor/taste in water. In both cases, these issues do not originate in PEX plumbing systems.
Possible solutions:
Install a water filter – see above.
Avoid installation and storage which may expose PEX to unpleasant or harmful odors."Ahh.. "Science"..
