What is WaterSense - and what does certification actually mean?
WaterSense is a voluntary partnership program run by the US Environmental Protection Agency.
Here's what it covers, what it requires, and why it matters for your facility or business.
EPA
The WaterSense program
Launched by the EPA in 2006, WaterSense sets efficiency and performance standards for plumbing fixtures - showerheads, faucets, toilets. Products must be certified by an EPA-accredited independent laboratory.
The WaterSense label cannot be self-declared by a manufacturer.
1
GPM
What certification requires
A WaterSense-certified showerhead must use no more than 2.0 GPM - at least 20% less than the federal standard of 2.5 GPM - while maintaining minimum spray force and coverage performance. Performance testing is done under a range of pressure conditions, not just at rated pressure.
1
+
Why it matters now
As of 2024, 14 states have adopted showerhead standards stricter than the federal baseline. Multiple states and cities now require WaterSense certification by law - not just preference. Federal agencies must purchase WaterSense-labeled fixtures under DOE procurement rules.

State and federal WaterSense requirements -
where it's mandatory
The federal standard is 2.5 GPM. As of 2024, 14 states have stricter rules. PurGuard360® at 1.8 GPM meets every requirement listed below.
Federal procurement (all federal facilities): The Department of Energy's FEMP program requires all federal agencies to purchase WaterSense-labeled showerheads and faucets where available. This is a purchasing requirement - not a preference - covering VA hospitals, military bases, and federal office buildings nationwide.
California
1.8 GPM max
Effective July 1, 2018. CEC Tier 2. Strictest statewide standard in the US. Applies to all showerheads sold or installed in California.
Mandatory
Oregon
1.8 GPM max
Oregon state standard set at 1.8 GPM, aligning with the West Coast. All showerhead sales and installations statewide.
Mandatory
Georgia
WaterSense by law
Water Stewardship Act SB370 (2010). All installed showerheads in new and renovated buildings must be WaterSense certified. Violations are a misdemeanor under state law.
Mandatory by statute
Washington
1.8 GPM max
Effective 2021. State adopted the 1.8 GPM standard, matching California. Applies to all products sold or installed statewide.
Mandatory
Colorado
2.0 GPM max
SB-103 (2014), effective September 2016. WaterSense certification satisfies this requirement by definition.

WATER EFFICIENCY · FLOW PERFORMANCE · CERTIFIED
Certified water savings. No compromise on pressure or performance.
The most common concern about low-flow showerheads is whether the shower still works properly. Here is how WaterSense addresses that, and how PurGuard360® is certified to meet both efficiency and performance requirements together.
Common concern
"Will a lower flow rate mean weaker water pressure?"
Flow rate (GPM) and water pressure (PSI) are different measurements. Flow rate is the volume of water delivered per minute. Pressure is the force behind it. A well-engineered showerhead at 1.8 GPM can deliver the same spray force and coverage as a 2.5 GPM model by optimizing nozzle geometry and spray pattern distribution.
1
How WaterSense addresses it
Performance is a certification requirement -
not just a marketing claim.
To earn the WaterSense label, a showerhead must pass independent testing for spray force and spray coverage at three pressure levels — 80, 45, and 20 PSI. Products that save water but fail the performance tests do not receive certification.
PurGuard360® passed all three.
1
Hollow fiber membrane - no flow restriction
The 0.08 µm filtration membrane inside PurGuard360® is engineered to maintain full shower flow with no measurable pressure drop across the filter. The 3,400 cm² filtration area is sized specifically to avoid becoming a flow restriction point.
1
Certified at three pressure levels
WaterSense performance testing requires minimum flow performance at 80, 45, and 20 PSI — covering high-pressure buildings, standard residential pressure, and low-pressure supply scenarios. PurGuard360® is certified to maintain acceptable spray force and coverage at all three.
1
2,700 gallons saved. Same shower experience.
EPA program data confirms that WaterSense-certified showerheads deliver a shower experience rated equal to or better than standard models in consumer testing, while saving the average household 2,700 gallons of water per year. Efficiency and performance are not a trade-off here.
