Eli5: Why are most public toilets plumbed directly to the water supply but home toilets have the tank?
In: 4741
Those are called Flush valve toilets (compared to flush tank toilets). Flush valves are preferred in commercial buildings mainly because they have a cheaper maintenance cost (less clogs, less stains on the bowl) so building owners don’t need to spend so much on cleaning/plumbing service calls.
Most house owners don’t mind occasional cleaning, and usually their pipes are not sized adequately anyway to use a flush valve.
If you go outside the city you’ll see more flush tanks because more buildings are on well water without a high pressure city water main.
