Answer 1

Residential construction generally uses far smaller water pipes and supply lines than what’s usually available in many commerical buildings.

Residential toilets are often connected by hoses of about 3/8″ in diameter, which doesn’t supply water fast enough to eliminate the need for a toilet tank (and the entire house may only have a 3/4″ connection to the utility provider)
