Trump’s curious push for more powerful shower heads gets shut off

But in December, as his administration was getting ready to depart, Trump’s Energy Department announced it had changed the rules for shower heads. The amount of water used in a shower was still capped at 2.5 gallons per minute. But the agency gave a new interpretation of the cap, saying water use would be measured per shower stall instead of per shower head. Many newer shower stalls have multiple shower heads. So three shower heads in one stall, for example, could allow for 7.5 gallons per minute.
