Commercial Faucets Attributes

Commercial faucets are the lavatory, sink, service and lab fittings specified for non-residential buildings: schools, hospitals, stadiums, food service. Three buyers hit the same record. The contractor bidding a Division 22 submittal filters on mounting centers and certification. The maintenance buyer filters on spout reach and cartridge. The MRO buyer filters on finish and lead time.

A commercial faucet is a configuration, not a product. One base model spawns hundreds of SKUs across handle, spout, aerator insert, metering cartridge, supply arm and finish, and the manufacturer encodes all of it in a suffix string (807-665PSHABCP) rather than in fields. The specs that separate those SKUs live only in the PDF spec sheet, as bullets: "Rated Operating Pressure: 20-125 PSI", "adjustable 2 to 25 seconds".

Then standards drift. ASME A112.18.1/CSA B125.1 pulled public lavatory flow to 0.5 gpm at 60 psi, and lead content moved to NSF/ANSI/CAN 372, while suppliers still send sheets reading "2.2 GPM" and "lead free" as prose.

Core

Every SKU needs these. Without them the record is not a product, it is a row.

Faucet Type
enum
Metering faucet

Top-level split. A metering faucet, a sensor faucet and a pre-rinse unit are not substitutes and are specified from different sections.

Mounting Type
enum
Deck-mount

Deck vs wall vs backsplash decides whether the unit fits the fixture at all. First filter a contractor touches.

Mounting Centers / Hole Configuration
enum · in
4 in. centerset (3-hole)

Single-hole, 4 in. centerset and 8 in. widespread are not interchangeable. Wrong centers means the faucet will not land on the drilled sink.

Spout Reach (center-to-center)
number · in
4-1/8 in.

Determines whether the stream clears the bowl rim and lands in the basin. Quoted C-to-C from the spout centerline on every spec sheet.

Activation Type
enum
Push-button metering

Push-button metering, infrared sensor, wristblade, lever or cross. Drives both the A117.1 answer and the maintenance parts list.

Flow Rate at 60 psi
number · gpm
0.5 gpm @ 60 psi

ASME A112.18.1/CSA B125.1 caps public lavatory (non-metering) faucets at 0.5 gpm tested at 60 psi. A bare number without test pressure is not a spec.

Finish
enum
Polished Chrome

Highest-cardinality variant axis and the one suppliers encode as a two-letter suffix. Drives price and lead time.

Manufacturer Part Number (MPN)
identifier
807-665PSHABCP

The suffix string carries the whole configuration. Contractors order by MPN off the approved submittal, not by description.

GTIN-14 / UPC
identifier
00671140004402

Required for marketplace listing, barcode receiving and any syndicated feed. Frequently absent on low-volume finish variants.

Country of Origin
enum
United States

Drives duty, and federal and state-funded jobs test against Buy American provisions. Spec sheets flag it; catalog records usually do not.

Differentiating

What buyers actually compare on. This is where catalogs win or lose the filter.

Spout Style
enum
Gooseneck

Gooseneck, rigid, swing, tubular or cast. Gooseneck is specified for lab and fill applications where a bucket must clear the spout.

Body Material
enum
Cast brass

Cast brass, chrome-plated brass or stainless. Sets durability for vandal-prone installs and feeds the lead-content answer.

Metering Cycle Time
range · s
2-25 s adjustable

Metering faucets run a fixed cycle, adjustable on better cartridges. Facility buyers spec run time directly to control water use and complaints.

Cycle Volume
number · gal/cycle
0.20 gal/cycle

ASME A112.18.1/CSA B125.1 caps metering faucets at 0.25 gal per cycle. Metering SKUs have no max flow rate, so gpm alone cannot answer code.

Power Source
enum
Battery (4x AA), hardwire optional

Battery, hardwired transformer, hydro-turbine or solar harvesting. Decides whether the job needs an electrician and a junction box.

Inlet Connection
text
1/2 in. NPSM female

Thread and size govern whether existing supply arms and stops reconnect. Common source of a second trip to the counter.

Compliance & identifiers

Standards, regulatory data, and the identifiers channels reject you for missing.

ASME A112.18.1 / CSA B125.1
boolean
Certified

The base plumbing fitting standard. No listing, no code approval, no inspector sign-off on a commercial job.

NSF/ANSI/CAN 372 Lead Content
boolean
Compliant (<=0.25% weighted avg)

Caps lead at 0.25% by weighted average across wetted surfaces. Mandatory for any potable outlet under federal and state lead law.

The fields that aren't in the schema at all

What most commercial faucets catalogs are missing.

The table above is the schema most catalogs already have. These are the attributes that usually aren't in it — each one surfaced by a signal from the live market rather than by an audit of what's already there. This is what Anglera's Schema Foundry does on a real catalog, in this category.

Supplier signal
+ Aerator / Outlet Type and Supplied Insert Flow Rate

Manufacturers ship one aerator installed and additional inserts in the carton (e.g. 1.5 gpm fitted, 0.5 and 2.2 gpm included). Catalogs publish a single gpm number and no outlet field at all.

Buyer specs to the printed gpm, receives a different fitted aerator, and the install fails the water-efficiency line item at job closeout.

Marketplace signal
+ Shank Length / Maximum Deck Thickness

Deck-mount faucets carry a shank length and a maximum mountable deck thickness on the dimensional drawing. Almost no distributor filter rail exposes either field.

Faucet will not draw down on a thick solid-surface or stone counter. Unit goes back as a return, and the counter is already drilled.

Supplier signal
+ Rated Operating Pressure and Temperature Range

Spec sheets state it plainly (Rated Operating Pressure: 20-125 PSI, Rated Operating Temperature: 40-140F). It sits in a PDF bullet and never reaches the catalog record.

Sensor and metering units on low static-pressure buildings underperform and get warranty-claimed as defective when they are simply out of range.

Competitor signal
+ Metering Cycle Time and Cycle Volume

Competitor rails let buyers filter metering faucets by adjustable run time. Most catalogs carry only a Faucet Type of metering plus a gpm figure that does not govern metering units.

Buyers cannot prove the 0.25 gal/cycle ASME cap from the record, so the SKU drops out of water-efficiency and green-building RFQs.

Search signal
+ Power Source and Backup Mode

Sensor faucets ship as battery, hardwired transformer, hydro-turbine or solar, often as separate SKUs under one base model. Records list them as one undifferentiated sensor faucet.

Wrong power variant ships. The electrician is on site with no transformer, or a hardwire-only unit lands on a job with no rough-in power.

How Schema Foundry finds these

Messy in, governed out.

The same value, spelled every way plumbing & PVF suppliers spell it. A filter only works once they agree.

Mounting Centers
4"4 inch centerset4in CCCenterset 4102mm4" C-C
4 in. centerset

Metric-sourced lines send 102mm for the same drilling. Ungoverned, the 4 in. centerset filter silently drops half the assortment.

Flow Rate
1.5 GPM1.5 gpm @ 60 psi5.7 L/min5.7 LPM1.51.5GPM
1.5 gpm @ 60 psi

Flow is meaningless without test pressure. ASME rates at 60 psi; a bare 1.5 cannot be compared to a 0.5 gpm public lavatory cap.

Finish
CPPCChromeChrome PlatedPolished ChromeChr
Polished Chrome

Finish arrives as a suffix code, not a field. The same finish lands under six labels and fragments the facet count.

Lead Content
ECASTLead FreeLFNSF 372AB1953<0.25% lead
NSF/ANSI/CAN 372 compliant

Vendor brand programs name the same certification. Marketing prose is not a filterable compliance flag.

What buyers ask

Every one of these should be answerable from the attributes above. If it isn't, that's a gap.

  • Will this fit a 4-inch centerset sink, or do I need widespread?
  • What's the spout reach? Will the stream clear the bowl?
  • How long does the metering cycle run, and can I adjust it?
  • Is it battery or hardwired, and what happens when the battery dies?
  • Is it certified to A117.1, or does it just say ADA in the description?
  • Is this lead-free for a potable outlet under state lead law?
  • Will it work on our building at 30 psi static pressure?
  • What size are the inlets? Will my existing supply arms reconnect?

Commercial Faucets data, in practice

Why can't I use gpm alone to spec a metering faucet?

Because ASME A112.18.1/CSA B125.1 regulates the two families differently. Public lavatory faucets other than metering are capped at 0.5 gpm tested at 60 psi. Metering faucets are not subject to a maximum flow rate at all; they are capped at 0.25 gallons per cycle. A metering SKU carrying only a gpm value cannot be checked against the standard that actually governs it, and it falls out of any water-efficiency filter. Metering records need two fields: cycle volume in gal/cycle, and cycle time in seconds (commonly adjustable, e.g. 2 to 25 s). Carry gpm too where the manufacturer publishes it, but do not let it stand in for cycle volume.

Should the compliance flag be called 'ADA compliant'?

No. The faucet is certified to ANSI/ICC A117.1, and that is what the spec sheet says. ADA compliance is a property of the installed assembly: it depends on mounting height (no more than 48 in. to operable parts), knee and toe clearance under the lavatory, and clear floor space. The fitting's contribution is that operable parts work with one hand, without tight grasping, pinching or twisting, at no more than 5 lbf. Label the field for what is certifiable, and A117.1 is it. A boolean called 'ADA' invites a contractor to assume the installation passes because the box does.

NSF 61 or NSF 372? Which belongs on the record?

Both, as separate fields. They test different things. NSF/ANSI/CAN 61 covers material safety and contaminant leaching into drinking water, and spec sheets often cite an annex result such as 'NSF/ANSI/CAN 61: Q <= 1'. NSF/ANSI/CAN 372 covers lead content specifically: no more than 0.25% by weighted average across wetted surfaces, the threshold federal and state lead law reference. Suppliers routinely collapse both into the phrase 'lead free', or into a brand program name for the same certification. Neither is filterable. Keep them as two flags and carry the 61 annex value as text where published.

Why does one base model produce hundreds of SKUs?

Commercial faucet lines are built as configurations. A single base model varies across handle type, spout style and reach, aerator or outlet insert, metering cartridge, supply arm, mounting centers and finish, and the manufacturer encodes every choice as a suffix on the part number rather than as structured fields. The result is a part number like 807-665PSHABCP that is fully descriptive and completely unfilterable. Enrichment in this category is largely decomposition: parsing the suffix grammar per manufacturer, pulling dimensional and pressure specs out of the PDF, and writing them back as governed fields so the variants become comparable.
