Fontana American Standard Deck-Mounted Sensor Faucet: Water Flow Schematic

This water-flow schematic resource is intended to support architects, plumbing engineers, contractors, installers and facility managers coordinating the Fontana American Standard deck-mounted automatic sensor faucet within commercial, hospitality, healthcare, institutional, public and residential lavatory environments. The technical drawing identifies the building water-supply inlet, service shutoff, optional hot-and-cold mixer, filter or strainer, solenoid valve, flexible connection, faucet inlet, internal water passage, aerator outlet, flow direction and sensor-controlled shutoff sequence.

Fontana American Standard Deck-Mounted Sensor Faucet

The Fontana American Standard Sensor Faucet delivers water through a sensor-controlled supply arrangement. When the infrared sensor detects a user’s hands within the approved activation field, the control system signals the solenoid valve to open and permit water to travel from the building supply through the concealed components and faucet body to the aerator outlet.

When the user’s hands leave the detection zone, the control system closes the solenoid valve and stops water delivery. The final supply arrangement, filter location, mixer configuration, solenoid orientation and connection sequence must be verified from the current product specification and installation instructions.

Required Water Flow Schematic Package

Each schematic should use a consistent symbol set, flow-direction arrows and product-identification block. The drawing should distinguish the building water supply, isolation valve, optional mixing component, filter or strainer, solenoid valve, flexible connections, faucet inlet, internal water passage and aerator outlet. Electrical signal paths should be shown only where needed to explain solenoid activation and automatic shutoff.

Water Flow Schematic

Shows the complete water-delivery path from the building supply to the faucet outlet. The schematic identifies the shutoff valve, optional mixer, filter, solenoid valve, flexible supply line, faucet inlet, internal passage and aerator outlet in the correct flow sequence.

Water-Supply Inlet

Identifies the point where the building water supply enters the faucet system. The supply connection should be coordinated with the plumbing drawings, available pressure and selected cold-water or mixed-water configuration.

Service Shutoff Valve

Shows the accessible isolation valve serving the faucet. The shutoff should remain reachable for installation, flushing, inspection, leak testing, component replacement and future maintenance.

Optional Mixer

Identifies the optional mixing component used when hot-and-cold water delivery is specified. The hot and cold inlets and mixed-water outlet should be clearly marked and connected in accordance with the approved installation documentation.

Filter or Strainer

Shows the model-specific filtration component positioned upstream of the solenoid valve. The filter or strainer helps reduce debris entering the valve and faucet passage and should remain accessible for cleaning or replacement.

Solenoid Valve

Identifies the electrically controlled valve that opens and closes the water path in response to the sensor-control signal. The valve should be installed in the approved orientation and flow direction.

Flow Direction

Uses directional arrows to show water movement through each component. The schematic should clearly communicate the sequence from the supply inlet through the shutoff, mixer, filter, solenoid, faucet and outlet.

Flexible Supply Hose

Shows the flexible connection between the concealed control assembly and faucet inlet. The hose should remain free from kinks, twisting, excessive tension, compression and contact with sharp cabinet or basin components.

Faucet Inlet

Identifies the connection through which controlled water enters the faucet body. The inlet connection should be secure, accessible and compatible with the approved supply hose and model-specific fitting arrangement.

Internal Water Passage

Illustrates the concealed route through the faucet body from the inlet connection to the outlet. The passage should be represented schematically and not used as a substitute for manufacturer service documentation.

Aerator Outlet

Identifies the final water-delivery point at the end of the spout. The aerator influences stream shape and outlet performance and should remain accessible for inspection, cleaning and model-approved replacement.

Sensor Activation Signal

Shows the control relationship between the infrared sensor and solenoid valve. When hands enter the approved detection field, the control system signals the solenoid to open the water path.

Automatic Water Shutoff

Explains that the solenoid valve closes after the user’s hands leave the sensing area or the programmed operating limit is reached. Shutoff behavior should be confirmed during final commissioning.

Engineering note: The water-flow schematic is a coordination diagram and should not be used to establish connection sizes, component orientation or final installation positions without verification. Confirm the supply configuration, operating pressure, shutoff location, mixer arrangement, filter or strainer, solenoid flow direction, hose connections and aerator requirements using the current FontanaShowers specification sheet, installation instructions and approved project submittal.

Water Flow Operating Sequence

Standby Condition

With no hands in the sensor field, the solenoid valve remains closed and water is retained upstream of the controlled valve.

Hand Detection

When the user’s hands enter the approved detection zone, the infrared sensor sends an activation signal to the faucet-control system.

Solenoid Opening

The control system energizes the solenoid valve, allowing water to pass through the controlled flow path toward the faucet inlet.

Water Delivery

Water travels through the flexible connection and faucet body before leaving through the aerator as a controlled handwashing stream.

Hand Removal

When the user’s hands leave the detection field, the sensor control no longer maintains the open-valve signal.

Solenoid Closing

The solenoid returns to the closed position and stops water delivery through the faucet outlet.

Automatic Time Limit

Model-specific automatic shutoff may limit continuous operation if an object remains within the sensing field. Verify the operating sequence from current documentation.

Return to Standby

After water flow stops, the faucet returns to standby and remains ready for the next valid sensor activation.

Plumbing and Service Coordination

Supply Pressure

Confirm that the available water pressure remains within the published operating range and is suitable for stable faucet and solenoid performance.

Supply Flushing

Flush the building supply before final faucet connection to reduce construction debris entering the filter, solenoid valve, internal passage or aerator.

Flow Direction Check

Verify the marked flow direction through the filter and solenoid valve before pressurizing the system.

Connection Security

Inspect all threaded, flexible and model-specific connections for correct engagement and sealing before operational testing.

Leak Inspection

Pressurize the system and inspect the shutoff valve, mixer, filter, solenoid, hoses and faucet inlet for visible leakage.

Filter Access

Locate the filter or strainer where it can be removed and cleaned without dismantling the basin or permanent cabinetry.

Solenoid Access

Maintain access to the solenoid valve for inspection, testing, cleaning and replacement while protecting it from standing water.

Aerator Maintenance

Inspect and clean the aerator when reduced flow or an irregular stream indicates debris or mineral accumulation.

Project verification: Water-flow schematics are coordination tools and do not replace approved product specifications, installation instructions or project submittals. The plumbing engineer, contractor and licensed installer should verify the final supply configuration, working pressure, shutoff location, optional mixer, filter or strainer, solenoid orientation, flexible connections, faucet inlet, flow direction, aerator condition, sensor-controlled opening, automatic shutoff, service access and locally adopted plumbing requirements before commissioning.
