What is a Pressure Compensating Showerhead or Aerator

lowflowshowerYou turn the knob of the shower and the water falls in a steady cascade. You’re enveloped in the falling beads of water, not too strong and not too weak. The thought of sacrificing such a luxurious shower experience for water efficiency is the furthest thing from your mind. But going green doesn’t mean we have to disregard our comfort. With pressure compensating showerheads and aerators we can achieve energy efficiency without sacrifice.

The water pressure is measured in Pounds per Square Inch (PSI) and can vary significantly in each home. The higher the PSI the higher the water pressure. It can be as low as 20 PSI whilst in others it can be as high at 80 PSI. In a low pressure home, the shower stream can feel very weak. This is further amplified when you have a lower flow showerhead. Fortunately this can be corrected with a pressure compensating showerhead, which essentially regulates showerheads and faucets. When pressure fluctuates, pressure compensation works to maintain efficiency and consistency so that the flow is kept constant when the pressure is between 40-80 PSI. This creates an optimal shower experience, giving you both peace of mind knowing you’re doing your part in saving water while still relishing in your shower experience.

The rubber ring expands depending on the pressure applied, in turn blocking the holes and reducing the amount of water coming through the tap. When pressure drops, the rubber ring is more relaxed, meaning more water is able to come through the holes in the tap. While the initial cost may be a bit more, you can expect to see a return of investment in typically less than two months.
