Rate of Flow versus Pressure
As is utterly predictable, grab the nearest diversion when the polls look bad.
"Donald Trumps hair has mesmerized many observers since he began his career in politics, but now the presidents own pride in his locks has prompted the US government to propose an easing of shower pressure standards. The Trump administration proposed rule changes that would allow shower heads to boost water pressure, after Trump repeatedly complained that bathroom fixtures do not work to his liking. The Department of Energy plan followed comments from Trump last month at a White House event on rolling back regulations. He said he believed water does not come out fast enough from fixtures." "The proposal would effectively allow shower fixtures to include multiple shower heads that would get around the 2.5 gallon per minute standard Congress set in 1992, when Trumps fellow Republican George HW Bush was president." Any volunteers to fit a high pressure (heavy duty industrial) jet washer in his shower? |

That's about 9.5 litres/minute (US uses gallons which are 4/5 the size of UK ones). Our cold water tap in the kitchen, next to the main stop tap, gives about 13 litres/minute (measured as time to fill a 2-litre jug) and I imagine that the nozzles in the shower heads will restrict the flow rate a bit. I presume if a US shower is driven from mains-pressure hot (and cold) water, and the mains happens to allow more than 2.5 USgall/min, a flow-rate restrictor has to be inserted in the head, where it will affect hot and cold water equally. Any volunteers to fit a high pressure (heavy duty industrial) jet washer in his shower? LOL. |

That makes it 10 l/m. |
