In college I had a job that required me to travel all over campus. I decided to grade the various water fountains as I traveled. I had stickers, red, yellow, and green to evaluate the quality, temperature and stream. So as I walked around campus I would place a sticker on every fountain I could find.
In general the model of fountain didn’t seem to matter much. It was clear some had been hooked up poorly or just had a poor water supply. But if the fountain was in a newer building or near a gym, then they were good quality.
Long way of saying it’s not always the fountain, sometimes it’s the infrastructure.
I always assumed that’s why the ones near the gym were some of the best. No one complains about a fountain they use sometimes, but one you use daily/weekly, you have to make sure it’s good.
