Answer 1

Here in Australia, household water is generally supplied by a 20mm connection where commercial properties are connected to 25mm or larger connections giving far greater water availability. The other thing that you’ll find is that many commercial buildings that have public toilets actually do have a standard cistern, only that they’re built into the wall, hidden away to protect them.
