Fontana Countertop Faucet & Soap Dispenser: Soap Dispensing System Diagram

This soap-dispensing-system resource is intended to support architects, plumbing engineers, contractors, installers, maintenance personnel and facility managers coordinating the Fontana countertop automatic soap dispenser within commercial and residential lavatory environments. The drawing identifies the refillable reservoir, peristaltic pump, flexible tubing, one-way check valve, soap nozzle, flow direction, priming path, operating sequence and typical system specifications.

Fontana Automatic Soap Dispensing System

This coordinated under-counter system stores liquid soap in a refillable reservoir and uses a peristaltic pump to move soap through food-grade flexible tubing toward the dispenser nozzle. A built-in one-way check valve helps maintain prime, reduce backflow and support consistent metered dispensing at each activation.

  • System purpose: Automatic liquid-soap delivery
  • Soap reservoir: Refillable bottle
  • Pump type: Peristaltic metering pump
  • Tubing material: Food-grade silicone
  • Check valve: Built-in one-way valve
  • Nozzle type: Controlled anti-drip soap outlet
  • Flow direction: Reservoir → Pump → Check Valve → Nozzle
  • Input voltage: 6–12 VDC
  • Soap viscosity range: 100–3,500 cP
  • Typical dose volume: 0.8–1.2 mL
  • Operating temperature: 1–55 °C (34–131 °F)
  • Compatible soap: Liquid hand soap; foam soap with appropriate pump
FontanaShowers Installation Guide

Required Soap Dispensing System Drawing Package

Each drawing should use a consistent component numbering system, flow direction graphic and priming-path notation. The package should clearly identify the reservoir, pump, tubing, check valve, nozzle, connection points and operating sequence. Soap compatibility, priming requirements, dose range and maintenance access should be documented for installation, commissioning and service.

Soap System Overview

Shows the complete relationship between the soap reservoir, peristaltic pump, flexible tubing, check valve and dispenser nozzle. This drawing provides an overall reference for installation, priming, service planning and project submittals.

Soap Reservoir

Identifies the refillable bottle that stores liquid soap beneath the countertop. The reservoir should remain upright, securely supported and accessible for removal, cleaning and refilling.

Peristaltic Pump

Illustrates the pump that draws soap from the reservoir and pressurizes the delivery line. The pump supports accurate metering, self-priming and repeatable soap delivery.

Flexible Tubing

Shows the food-grade, kink-resistant tubing connecting the reservoir, pump, check valve and nozzle. Tubing should be routed without pinching, excessive bends or contact with sharp edges.

One-Way Check Valve

Identifies the valve that maintains system prime and reduces reverse flow after dispensing. Correct orientation is essential for reliable operation and reduced dripping at the nozzle.

Soap Nozzle

Shows the final dispensing outlet at the countertop fixture. The nozzle delivers a controlled quantity of soap and incorporates an anti-drip configuration for cleaner operation.

Flow Direction

Defines the normal soap path from the reservoir through the pump and check valve to the nozzle. Flow-direction arrows should remain visible in installation and service documentation.

Priming Path

Illustrates the route used to purge air during initial installation or after refilling. Priming should continue until a steady, uninterrupted stream reaches the dispenser nozzle.

Operating Sequence

Summarizes user activation, pump operation, soap movement through the check valve, metered dispensing and system reset. This sequence supports commissioning and troubleshooting.

Engineering note: The soap-system diagram is a coordination reference and should not be scaled. Use only compatible liquid soap and approved components. Verify tubing routing, valve orientation, pump operation, priming, dose volume and maintenance procedures against the current product specification and installation instructions before placing the system into service.

Installation and Maintenance Coordination Considerations

Soap Compatibility

Use liquid soap within the specified viscosity range and avoid gels, beads or suspended particles that may restrict the tubing or pump.

Tubing Routing

Route tubing in smooth curves without kinks, flattening, excessive length or contact with sharp cabinet edges.

Priming

Prime the system after installation, after refilling or whenever the dispenser has been unused long enough for air to enter the line.

Check-Valve Orientation

Confirm the one-way valve is installed in the indicated flow direction so soap can reach the nozzle and backflow is minimized.

Nozzle Cleaning

Inspect and clean the nozzle regularly to prevent dried soap buildup, reduced flow and irregular dose delivery.

Service Access

Keep the reservoir, pump, tubing connections and check valve accessible for inspection, cleaning, refilling and component replacement.

Professional Engineering and Accessibility References

Project verification: Soap dispensing system diagrams are coordination and service tools and do not replace approved project submittals. The plumbing engineer, contractor, facility manager and qualified installer should verify soap compatibility, pump type, tubing material, check-valve orientation, nozzle condition, priming procedure, dose settings, service access and manufacturer requirements before installation, commissioning or maintenance.
