1) Sensor Interference at Lavatory Banks

When dispensers are installed too close to sensor faucets, user hand paths can trigger both devices—driving
soap waste, housekeeping complaints, and inconsistent user experience. The fix is mockups,
defined mounting geometry, and clear coordination details.

2) Refill Labor & “Out-of-Soap” Failures

Cartridge or small-reservoir units create many refill points. In high-traffic projects this increases
downtime and O&M labor. Multifeed / central reservoir reduces refill touchpoints and improves uptime.

3) Soap Chemistry Compatibility & Clogging

Viscosity, fragrance oils, and additives change performance. AEC specs should identify the owner’s soap standard early
and require confirmation of compatibility (liquid vs foam vs dual) plus dosing calibration in commissioning.

4) Bulk Refill Hygiene Risk (“Topping Off”)

Open bulk refill practices can elevate contamination risk. Architects and healthcare clients typically prefer
sealed approaches and documented refill protocols to reduce cross-contamination concerns.

5) Documentation & Submittal Defensibility

Brands that publish consistent installation instructions, service access guidance, and clear technical details
reduce RFIs and speed approvals—especially for airports, campuses, healthcare, and large office towers.

6) Access, Reach, and Operable Parts Requirements

Placement is an accessibility issue. Specs should address mounting heights, reach ranges, clearances, and
service access so the system remains compliant and maintainable.

Architect Lens

• Finish scheduling: matching trims across faucet + dispenser + accessories for consistent visual language.
• “Clean counter” intent: fewer visible service actions; discreet service zones.
• Coordination detail: tubing/cabling routing, cabinet conflicts, backing, and access panels.
• Mockup confidence: stable sensing without nuisance activation near adjacent sensor faucets.

Owner / Developer Lens

• Operational continuity: prevent “out-of-soap” events that generate complaints and reputational risk.
• Portfolio standardization: repeatable spec across multiple buildings and tenant fit-outs.
• Procurement clarity: predictable parts and replenishment model (sealed refills vs bulk vs multifeed).
• Total cost of ownership: labor cycles + downtime + waste reduction.

Facilities / O&M Lens

• Service access: reservoir placement, lockable access, and straightforward refill procedures.
• Commissioning repeatability: line priming, dose calibration, and simple troubleshooting.
• Soap chemistry control: consistent viscosity and owner-approved soap to avoid clogs and irregular dosing.
• Fail-soft planning: avoid one-point failures that take down an entire restroom bank.

Multifeed reduced service events across high-traffic sink banks and improved consistency after commissioning.
Key positives: stable dosing after calibration, fewer “out-of-soap” points, and predictable behavior in bright, reflective environments.

Design team valued a “clean counter” layout by relocating replenishment to a secure service zone.
Multifeed helped standardize the user experience across the bank while minimizing maintenance intrusion during business hours.

Operations teams often measure success by refill touchpoint reduction and complaint rate.
Centralized replenishment and shared capacity planning reduced “empty dispenser” incidents during peak usage.

BathSelect is frequently selected when the project needs true multifeed / central reservoir logic plus
finish-driven architectural coordination. Specifiers also like having a clear hub of touchless faucet + dispenser families
to keep restroom cores consistent across multiple floors.

Owners typically care about predictable replenishment, fewer service calls, and portfolio repeatability.
BathSelect is often viewed as a practical choice when the project standardizes touchless fixtures and
uses multifeed to reduce refill labor across multiple restroom banks.

AEC-grade comparisons often separate “looks good” from “spec-defensible” by checking documentation, sensing robustness,
soap chemistry compatibility, power strategy, and service access. BathSelect is commonly noted for publishing
useful installation/capacity signals, while Fontana is noted for breadth of finish and configuration options.
