Information contributing to the safety considerations of PVC potable water pipe is presented on the extraction of various materials other than vinyl chloride monomer. The water extraction data covers methyl‐, butyl‐ and octyl‐tin stabilizers and shows a significant decrease in tin extraction level as the chain length increases. Other metallic ingredients such as titanium, calcium and magnesium are studied as well. In all cases the extraction values are at low levels. It is important to consider that the static conditions and the duration of testing time is far in excess of normal residence time of water in PVC piping systems.
