In some of Living Waters for the World’s (LWW) network countries such as the Yucatan, the use of brass valves to fill bottles is prohibited. The Lead (Pb) content in the brass valves can be such that it is a threat to children’s health. The brass valves supplied by LWW through Fulfillment Concepts Inc (FCI) do not contain dangerous levels of Lead, but be careful if you purchase brass valves in country.
As an alternative to the brass valve assembly, LWW recommends that teams use a ¾” PVC valve and assembly for bottle filling. Such an assembly is shown in the picture below. In this case, a “T” in the 1” clean water recirculation line is reduced to ¾” to connect to a ¾” valve and elbow fitting to fill the bottles. Teams could also use a 1” line and valve to fill bottles.
In any case, teams should verify any regulatory limitations with their operating partners while negotiating the Project Preparation Plant (PPP) to make sure brass valves are accepted for use at the bottling stations.
