COLD WATER STORAGE – Water tank must be in good condition. If you rely on a tank for your drinking water it should meet the following requirements: not too large, so the water in the tank is frequently replenished with fresh water. Traditionally tanks were made of galvanized iron and these rust over time leading to metal bits in the water or brown or yellowish tinge or a metallic taste. Nowadays tanks are constructed of stainless stell and plastic (polyethylene) and unlikely to cause problems provided that are designed for drinking water purposes and have a close fitting cover.
