Soda machines have water filters on them because brands (and distributors) require crystal-clear water to be supplied to the soda machines so that colored sodas aren't off-color and clear sodas (Sprite, 7-Up, tonic water, soda water, etc.) remains crystal-clear before it makes its way to the customers.

The water filters are designed to remove rust (iron) particles from water, so as long as the color is from rust particles, those won't make it to the customer's glass.

The restaurant, however, will be going through water filters more quickly the longer this goes on. That'll clog them up and cause the water to flow more slowly while the syrup ratio continues unchanged and really throws the taste of the soda off.

Yes, this can cause the water mains and pipes to vibrate from the sudden change in water pressure and shake some rust (iron) particles loose. This happened often when I lived in Fort Lauderdale and usually resolved within an hour or two.

After that, the water would be cloudy from the extra-fine air bubbles (you can hear the fizzing and see the water clear up after a moment) that was pushed into the water.

The water that goes into soda taps/machines almost certainly has a filter on it, so it's clear when it comes out and goes into glasses. Guaranteed they are not serving brown water to customers. If they are, then customers are definitely going to complain.

If anything, their filters are going to start to get clogged much faster and they're going to be moving through them more quickly. The mix from carbonated water to syrup will be thrown off and everything will taste sweeter or "more chemically" for diet sodas and customers will also complain.

ETA: Source is that I've watched distributors and inspectors test and inspect soda machines, test the water to syrup ratio, and we would get dinged if the soda mix was off, which may have been because of clogged filters that weren't performing as expected (water flowed slower and the syrup mix was left as-is). If we received more than a handful of points, the distributor or brand (Coca-Cola at the time) would fine us and threaten pulling their products. It was usually fixed by simply replacing the filter, restoring the water pressure and returning the water-to-syrup ratio back to the intended mix.

R22 was installed in new systems as late as 2010. If the life of a unit on average is 15 years, with some lasting longer, it’s safe to assume there are still plenty out there kicking. Even R-410A, the most common today, it isn’t great for the ozone. It is banned effective Jan 1 2025.
