Counts of accepted identities. The complete distribution and denominator follow below.
Two different product tasks share this directory
The saved population contains 19,089 Faucet identities and 1,974 Faucet Accessory identities: 90.63% and 9.37% of 21,063 records. Choosing a complete faucet and researching an accessory are different tasks. The same GPM does not establish thread fit, assembly compatibility or installation suitability.

Denominator: 21,063 accepted identities; known field values: 21,063; UNKNOWN: 0. Shares describe this saved catalog, not sales or household installations. Positive shares below 0.01% are shown as <0.01%, not zero.
The 1.2 GPM group contains 12,675 identities (60.18%); 1.5 GPM contains 6,738 (31.99%). These groups combine both source product types. Their counts must not be described as numbers of complete faucets.
Read the rating with its test context
EPA's bathroom sink faucet technical sheet describes the WaterSense maximum at 60 psi and a minimum-flow criterion at 20 psi. The directory has one reported maximum-flow field, not a model-specific pressure-response series. Actual flow can differ with supply pressure and the installed assembly.
EPA bathroom sink faucet technical sheet. This category does not establish suitability for kitchen faucets or public lavatory applications.
Turn a rating into a clearly bounded estimate
For two minutes of actual flowing time, constant 1.2 and 1.5 GPM assumptions yield 2.4 and 3.0 US gallons. The 0.6-gallon difference assumes equal time and conditions. Do not use total time spent at a sink when water is off for part of it.
The household calculator currently models showers and toilet flushes; it does not silently add faucet use. Keep this faucet estimate separate or use the stated multiplication directly.
Before selecting a replacement
- Check whether the source row is Faucet or Faucet Accessory.
- Retain the literal brand and model; shared model text is not a universal identity.
- Obtain the manufacturer's fit and installation documentation separately; these details are absent here.
