BERKELEY, Calif.—Showering during California’s drought is a guilt-free experience for homeowners Catarina Negrin and Noah Friedman.

The Berkeley couple — she runs a pre-school, he’s an architect — are early adopters of a home plumbing do-over that’s becoming more popular during California’s record four-year dry stretch.

California, like many states, long required all water used in homes to be piped out with the sewage, fearing health risks if water recycling is done clumsily.
