Benefits of Low-Flow Plumbing Fixtures

California’s historic and prolonged drought receives the majority of headlines, but many other areas of the United States experience abnormally dry or Low Flow Fixtures Will Save Everyone Moneysevere drought conditions every year as well. Lack of rainfall and increased water usage during a drought often combine to create water shortages and higher water rates that could impact your business.

Strict Water-Saving Measures Get Even Stricter

In response to current and future drought conditions, some cities and states have water conservation regulations in place to help reduce water use and discourage waste. Additionally, many local water agencies are now imposing surcharges, fees, and penalties to help deter and prevent excessive water use.

California already has some of the strictest, low-flow water standards in the nation, and the state is enacting even more stringent water-conserving legislation in 2016. To be compliant with water conservation laws in California and other states, residential and commercial water-saving devices such as low-flow showerheads, faucets, and toilets are required to be even more efficient with lower GPMs (gallons per minute) and GPFs (gallons per flush). For example, kitchen faucets sold in California after January 1, 2016 cannot exceed 1.8 GPM and showerheads sold in California after July 1, 2016 cannot exceed 2.0 GPM.

Although many states allow higher GPMs and GPFs for plumbing products, low-flow showerheads, faucets, and toilets that conform to the California standards are the ones most manufacturers and suppliers are now making available to customers nationwide.

Water-Saving Tips

Even in areas where drought is not a problem, conserving water is in everyone’s best interest. You can’t control the amount of rainfall or weather conditions, but you can reduce water use by doing the following:

Low-flow aerators are one of the most effective water conservation methods available.

  •   Install low-flow aerators on kitchen, bath, and public washroom faucets. Aerators are easy and inexpensive to replace and are one of the most effective water conservation methods available. 
  • Replace high-flow 2.5 or 2.2 GPM showerheads with low-flow 2.0 to 1.5 GPM models. 
  • Repair or replace leaky faucets. According to, one water drip per second wastes 1,661 gallons of water per year
  • Replace water-guzzling toilets to save water and money. Older models may require three to five gallons of water per flush. Dual flush and low-flow toilets feature 1.6, 1.28, or as low as 0.8 GPF. 
  • Look for WaterSense® labeled plumbing products that meet EPA standards for water efficiency and performance.
