Sensor Control Valve Scope
The installation detail should show the relationship between the building
water supply, sensor-controlled valve, faucet outlet connection, electronic
control wiring and service-access zone. The valve should be securely
supported, correctly oriented for water flow and positioned where plumbing
and electrical connections remain accessible. Only verified manufacturer
dimensions should be used in final construction documents.
Complete Valve Assembly
Show the incoming water supply, sensor control valve,
faucet connection, wiring and service zone in one coordinated view.
Valve Position
Locate the control valve within the concealed installation zone
where plumbing and electrical connections remain accessible.
Valve Orientation
Install the valve in the approved orientation so water passes
correctly from the supply side toward the faucet.
Flow Direction
Identify the direction of water movement through the control
valve toward the wall-mounted spout.
Valve Inlet
Show the building water supply entering the inlet side of
the sensor-controlled valve.
Valve Outlet
Show the controlled outlet connection leading from the valve
toward the faucet waterway.
1/2-Inch NPT Supply
Identify the 1/2-inch NPT water connection and maintain
sufficient working clearance around the threaded interface.
Supply Alignment
Align incoming piping with the valve inlet so the assembly
is not subjected to unnecessary side loading.
Valve Support
Secure the control valve independently to suitable structure
rather than allowing connected piping to support its weight.
Structural Backing
Provide appropriate backing or mounting surfaces where required
to maintain stable valve positioning.
Sensor Connection
Show the control connection receiving the activation signal
from the faucet sensor system.
Control Cable Route
Route the low-voltage valve-control cable away from sharp
edges, moving hardware and plumbing joints.
Cable Connector Access
Keep connectors visible and reachable for commissioning,
diagnostics and future replacement.
Controller Relationship
Show the valve positioned within the approved cable reach
of the electronic controller.
Power Separation
Maintain appropriate separation between plumbing joints
and electronic power components.
Isolation Access
Provide accessible water isolation so the control valve can
be serviced independently where required.
Joint Clearance
Maintain sufficient space around inlet and outlet fittings
for assembly and leak inspection.
Tool Access
Provide working clearance for installation tools without
interference from framing or adjacent components.
Moisture Protection
Position electronic connectors away from probable leakage
points and areas subject to standing moisture.
Wall Cavity Clearance
Keep the valve assembly clear of studs, blocking and
unrelated concealed building services.
Service Access Zone
Reserve sufficient space around the valve for inspection,
cleaning, diagnostic testing and replacement.
Removal Clearance
Provide an unobstructed removal path so the valve can be
replaced without unnecessary wall demolition.
Leak Inspection Zone
Keep inlet and outlet joints visible or service-accessible
during pressure testing and commissioning.
Finished Valve Installation
Show the completed sensor control valve securely supported,
correctly connected and accessible for future servicing.
Engineering note:
Sensor control valve installation dimensions must not be based on estimated
product measurements. Confirm valve orientation, connection size, cable
reach, controller relationship and service-clearance requirements from
the approved FontanaShowers specification sheet or project submittal
before plumbing rough-in.
Required Control Valve Views
Valve Installation Elevation
Show the control valve, inlet, outlet, support and
primary service-access zone.
Side Valve Section
Show valve depth, wall cavity, plumbing connections
and surrounding clearance.
Hydraulic Connection View
Show the building supply, valve inlet, valve outlet
and faucet water path.
Control Wiring View
Show the sensor, electronic controller, valve-control
cable and connector relationship.
Valve Support Detail
Show the structural support securing the valve independently
of connected piping.
Flow Direction View
Show the correct water-flow direction through the
control valve toward the faucet.
Service Access View
Show the working space required for valve testing,
inspection and removal.
Finished Installation
Show the completed concealed valve arrangement after
plumbing and control connections are finalized.
Recommended Valve Installation Sequence
1. Review Approved Submittals
Confirm the final valve configuration, connection requirements,
control arrangement and approved installation information.
2. Establish Valve Location
Reserve a concealed location providing adequate plumbing,
electrical and service clearance.
3. Install Valve Support
Provide rigid backing or mounting support before making
final plumbing connections.
4. Verify Flow Direction
Confirm the inlet and outlet orientation before securing
the valve assembly.
5. Connect Water Supply
Connect the incoming 1/2-inch NPT water supply without
forcing or twisting the valve.
6. Connect Faucet Outlet
Complete the downstream connection from the control valve
to the wall-mounted faucet waterway.
7. Route Control Cable
Route the valve-control cable toward the controller while
maintaining protection from sharp edges and plumbing joints.
8. Connect Controller
Complete the approved control connection between the valve
and electronic controller.
9. Flush Water Supply
Flush the supply piping before final operation so construction
debris does not enter the valve or faucet.
10. Pressure Test
Pressurize the plumbing system and inspect valve inlet and
outlet connections for leakage.
11. Test Sensor Operation
Activate the faucet and confirm the valve opens and closes
reliably in response to the sensor signal.
12. Verify Service Access
Confirm the valve and connectors remain accessible before
permanent wall finishes are completed.
Valve Commissioning Requirements
Activation Test
Move hands into the sensor zone and verify the control
valve opens consistently.
Shut-Off Test
Remove hands from the detection zone and confirm the valve
closes promptly.
Repeated Cycle Test
Complete multiple activation cycles to verify stable valve
response and reliable operation.
Leak Test
Inspect all inlet and outlet joints while the water supply
is pressurized.
Flow Test
Confirm water flows consistently through the valve and
reaches the faucet outlet correctly.
Connector Test
Verify electrical connectors are fully seated, dry and
secure during repeated operation.
Sensor Response Test
Confirm sensor activation produces corresponding valve
operation without intermittent response.
Final Functional Test
Complete final activation, flow and shut-off testing before
the installation is placed into service.
Architectural and MEP Coordination
Plumbing Coordination
Coordinate valve inlet and outlet piping with the approved
faucet rough-in and water-supply arrangement.
Electrical Coordination
Coordinate valve-control wiring with the sensor, controller
and approved power configuration.

Protect control wiring and connectors from plumbing leakage
and potential standing moisture.
Access Coordination
Locate access provisions directly in relation to the
serviceable valve and control components.
Sensor Coordination
Verify sensor signals reach the controller and valve reliably
during final commissioning.
Maintenance Coordination
Maintain sufficient working space for valve inspection,
cleaning and replacement throughout the fixture lifecycle.

Project verification:
This sensor-control-valve installation resource is intended for coordination
and does not replace an approved project submittal. The architect, plumbing
engineer, electrical engineer and licensed installer should verify final
valve type, connection size, flow direction, mounting position, cable reach,
controller relationship, power requirements, service access and locally
adopted codes before rough-in or installation.
