Higher quality pressure regulators can keep the pressure steady while allowing 4-4.5 gallons per minute of water flow.
The Watts regulator can reach 9 gallons per minute.
All three regulators will keep the water pressure at 50 pounds.
But for a four minute shower:
Camco - $7-8 = 6-8 gallons of water
Valterra - $50-70 = 15-18 gallons of water
Watts - $120-180 = 36-40 gallons of water
Those numbers ignore the EPA imposed 2.2 GPM limit on faucets and fixtures. That 4 minute shower should not exceed 8.8 gallons regardless of the available flow rate above that.
