Movie theaters along with restaurants, fast food chains and convenience stores, use soda fountain machines to dispense carbonated soft drinks. These machines are usually important to generating revenue, so it is a priority to keep them running smoothly.
Soda dispensing machines combine flavored syrup or syrup concentrate and carbon dioxide with chilled and purified water to make soft drinks. Soda’s carbonation and low acidic pH levels (2.0-3.0) easily cause corrosion build-up in the steel pipes typically used for waste drainage of these dispensing machines. This corrosion eats through the steel pipe causing leaks and at some point requiring pipe replacement – both costly and inconvenient for the fountain machine owner. The amount the dispenser is used, type of liquid, oxidation, temperature etc… all go into determining the speed at which corrosion will attack the steel pipe, so it is difficult to determine how long a given drainage system will last.
