Bubblers should be installed only on which type of fixtures?

Bubblers are specifically designed for drinking water applications, primarily to provide a clean and accessible way for individuals to hydrate. Therefore, the appropriate installation of bubblers is limited to drinking fountains, where they serve the purpose of allowing users to get water directly from a spout while minimizing the risk of contamination. This avoids the handling of cups or other vessels, aligning with health and safety codes for public water access.

In contrast, kitchen sinks, bathtubs, and showers are not suitable for installing bubblers. Kitchen sinks are typically used for food preparation and dishwashing, requiring different plumbing fixtures that allow for cleaning rather than direct drinking. Bathtubs are intended for bathing and personal hygiene, which does not necessitate a bubbler function. Showers, similar to bathtubs, are designed for washing rather than drinking. Installing bubblers in these contexts could pose health risks by introducing potential contamination from bath or shower water, which is not suitable for consumption. Thus, the correct fit for bubblers remains strictly within drinking fountains.
