Water Piping Material

Not really up for a detailed market summary, but here are a few points learnt for consideration.

• metal or polymer pipes all corrode, eventually
• metal has an solubility advantage where water is hot, but some PE/PEX materials can take hot water too
• polymer has an solubility advantage where water is softer, or has lower pH
• polymer should never be exposed to UV (i.e. try your best to keep it indoors)
• polybutene-1 has had a problem attributed to reactivity with halogen ions

I actually have been starting to think that glass piping would be an awesomely novel design choice.
