What type of plastic pipe is used for distilled water and de-ionized water systems?

PVC
CPVC
Unpigmented polypropylene
Polyethylene

The correct answer is: Unpigmented polypropylene

Unpigmented polypropylene is used for distilled water and de-ionized water systems because it offers high chemical resistance and is non-toxic. PVC and CPVC may contain additives and pigments that can potentially leach into the water, making them unsuitable for these systems. Polyethylene is also not as chemically resistant as polypropylene, making it a less ideal option for these types of water systems.
