As an Architect and Builder/Developer I can tell you that by IBC building codes, ABS can only be used as a drain line. I/E. Sewer, raindrains, Ect. it is not approved for pottable water.
Neither ABS or PLA will degrade much in water. ABS, PLA, and Nylon all are hydroscopic, but that does not mean they will absorb a bunch of water and then start degrading. They can only absorb so much water, and then they are fine. They are plastic, after all.
PVC is a cost-effective and durable option for potable water (Drinking Water).
Most schedule 40 PVC found in homes and offices is white pipe with a National Sanitation Foundation (NSF) rating for potable water. The drawbacks with this type of PVC pipe are that it will degrade when exposed to short wave UV light (contained in sunlight) and at higher temperatures, it will soften.
Chlorinated Polyvinyl Chloride Piping (CPVC) As implied by its name, CPVC is PVC piping with a higher chlorine content. CPVC is suitable for hot water and drinking water, unlike normal PVC. Compared with copper, CPVC pipes are smoother, and they produce less noise when water flows through.
Copper. Copper pipes are probably the most traditional plumbing pipe used due to their extensive duration and reliability. They provide superior corrosion resistance, great material to be used for hot and cold water, and it can be managed easily.
Both copper and PVC have their uses in modern water distribution systems. Copper, on one hand, is a strong, yet flexible metal that is often the first choice for home plumbing. Professional plumbers and contractors often use copper because it can be used to form pipes with thin but strong walls.
HDPE (High Density Polyethylene) pipes are a considered the best choice for underground water lines. What makes this type of piping so great? HDPE pipes are non-toxic, tasteless, and considered a green building material. The pipes are designed to be high crack- and corrosion-resistant.
Faced with a life-or-death situation, the young Avatar entered the Avatar State and froze himself with Appa in an iceberg, the latter was stuck in hibernation along with Aang for one hundred years.
Aragorn died at the age of 210 by choice so that his son, Eldarion, could rule. Arwen didn't want Aragorn to die, because if he died so would she. She said she wasn't tired of living yet. But instead, Aragorn chose to die and Arwen lived a year longer before dying herself.
