I read recently that Donald J. Trump wants to “open up” the standard of water-saving regulations, citing, among other things, Americans flushing toilets “10 times, 15 times as opposed to once.”

The several low-flow toilets I’ve had occasionally require two flushes, but those occasions are rare and the water savings, especially considering usage across the country, are tremendous. What’s more, most people urinate rather more often than they defecate (Trump is full enough of it that he could be an exception both for frequency and number of flushes), and more than a single flush is never necessary to clear urine.

Unless as a country we believe water conservation is unnecessary, our current standards should be left alone.
