Where is PEX available?
PEX is available through most plumbing wholesale distributors throughout the United States and Canada. Many retail building supply outlets also supply PEX piping and fittings. Piping and fittings are commonly available in 1/4″ through 1″ CTS (Copper Tube Size) with some manufacturers also supplying larger sizes up to 2.” Because the wall-thickness is proportionate for each size, the pressure ratings are the same for all sizes.
