Those figures for newer shower flow rates are totally bogus.
What idiot in their right mind can’t figure out that you need to be wet and rinsed off no matter the flow rate?
Reduced flows mean that it simply takes longer to get wet and rinse off.
The five minute shower becomes a ten minute shower.
Simply brilliant.
I solved the problem in two ways. I took out the limiter inside my shower heads and then added a 2nd shower head with a splitter
Reminds me of Dad teaching us girls how to take a ‘Navy Shower.’
Water on - get wet. Water off. Soap up. Water on. Rinse off. NOW GET THE HELL OUT OF MY BATHROOM AND QUIT WASTING MY WATER!
Yes, Captain, My Captain, LOL!
