What deck preparation is required for a parallel-stem motion sensor faucet?

Verify mounting hole diameter, deck thickness, basin clearance, spout reach, sensor field, supply routing, and under-deck service space before installation.

What power requirements should be reviewed for automatic faucet operation?

Review the required power source, battery or transformer location, wiring route, grounding method, control module access, and compatibility with the electronic control system.

How should the sensor detection range be adjusted during commissioning?

The sensor range should be adjusted based on basin geometry, mounting height, ambient lighting, reflective surfaces, and expected user hand position.

What plumbing conditions support reliable solenoid valve operation?

Stable operating pressure, clean supply lines, accessible filters, properly sized shut-off valves, and flushed piping support reliable solenoid valve performance.

Should supply lines be flushed before connecting the electronic control assembly?

Yes. Supply lines should be flushed to remove construction debris, sediment, and scale that could obstruct the solenoid valve, filter, aerator, or internal waterway.

What under-deck clearance is required for maintenance access?

Maintain clearance for the control box, solenoid valve, power source, filters, shut-off valves, wiring connections, and future maintenance access.

How can false activation be reduced in commercial restroom installations?

False activation can be reduced by correct sensor alignment, proper detection range adjustment, stable lighting, and avoidance of highly reflective basin surfaces.

What final commissioning checks should be completed before turnover?

Verify sensor response, automatic shut-off timing, leak-free connections, solenoid operation, water flow, power continuity, fixture stability, and finish condition.

Infrared Stability	April 16, 2026
Reviewer: Victoria Monroe, Infrastructure Specialist from Beverly Hills, CA

Following several luxury hospitality restroom renovations where decorative gold sensor faucets repeatedly developed unstable response timing and visible coating wear, we upgraded multiple properties to the Gold Parallel Stembetween 2021 and 2024.The faucet delivered a much stronger balance between architectural appearance and long-term reliability. Sensor activation remained stable throughout continuous guest usage, while the gold finish resisted corrosion and cleaning-related surface degradation exceptionally well.Technically, the parallel stem configuration improved water delivery alignment and reduced splashback around sink surfaces, helping maintain cleaner countertop conditions in high-traffic restroom environments.

NextGen Handsfree Edge	March 12, 2026
Reviewer: Megan, White from New York, New York

For a project that required hands-free performance and a finish that would still present well after repeated daily use, the Gold BathSelect Automatic Sensor Faucet (BS109-G) proved to be a strong fit. The operating performance is strong from a technical standpoint: the sensing window activates quickly, shutoff timing is controlled, and water delivery remains consistent. The gold finish works especially well in projects where both corrosion resistance and visual presentation matter. For contractors and maintenance staff, the unit is easier to work with than many low-grade sensor fixtures. Access, stability, and overall fitment support a smoother install and a more predictable ownership experience. Support was another strength. BathSelect’s team provided solid product guidance and helped resolve setup questions efficiently, which is exactly what commercial buyers want from a fixture supplier. Overall, it performs like a well-considered commercial restroom fixture: dependable activation, durable construction, and a finish package that supports both design intent and long-term ownership value. As a Healthcare Planner, delayed sensor response was a constant complaint. This BathSelect model activates instantly and consistently, improving user experience in high-traffic restrooms. The upgrade was immediately noticeable.

Great product	February 2, 2023
Reviewer: Billy from New York

This auto motion sensor faucet exceeded my expectations and was very easy to install. I absolutely adore this faucet. Spent quite a few months browsing different faucets online and in stores only to find that the ones I liked were either very expensive or not the right style. This faucet is pretty sturdy.
