Pasos de instalación
- Cierre el suministro de agua: Locate the main water shut-off valve for your home and turn it off. Open nearby faucets to drain residual water from the lines.
- Prepare Rough-in Opening: Ensure the wall opening is appropriately sized for the valve body. The valve should be securely mounted to a stud or blocking within the wall.
- Conectar líneas de agua: Identify the hot and cold water inlets on the valve. Connect the hot water supply to the port marked 'H' and the cold water supply to the port marked 'C'. Connect the shower outlet to the top port and the tub spout outlet (if applicable) to the bottom port. Use appropriate plumbing techniques (soldering, threading with sealant) to ensure watertight connections.
- Asegure la válvula: Mount the valve securely to the framing using appropriate fasteners. Ensure the valve is level and plumb.
- Prueba de fugas: Once all connections are made, slowly turn on the main water supply. Inspect all connections for leaks. If leaks are detected, turn off the water, tighten connections, and retest.
- Instalar el kit de molduras: After successful leak testing and wall finishing, install the decorative trim kit (handle, escutcheon, etc.) according to the trim kit's specific instructions.

Instrucciones de funcionamiento
The Phylrich Pressure Balanced Shower Rough Valve operates in conjunction with its corresponding trim kit. The rough valve itself controls the mixing of hot and cold water to maintain a consistent temperature, even with fluctuations in water pressure from other household fixtures.
- Control de temperatura: Rotate the handle (part of the trim kit) to adjust the water temperature. Typically, rotating counter-clockwise increases hot water, and clockwise increases cold water.
- Control de volumen: If your trim kit includes a separate volume control, rotate or pull the handle to adjust the water flow rate.
- Desviador (si corresponde): If your system includes a tub spout, use the diverter on the trim kit to switch water flow between the showerhead and the tub spout.
The pressure-balancing mechanism within the valve automatically adjusts to maintain your selected temperature, providing a comfortable and safe showering experience.
Mantenimiento
Regular maintenance ensures the longevity and optimal performance of your Phylrich Pressure Balanced Shower Rough Valve.
- Limpieza: Clean the visible parts of the trim kit regularly with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive pads, as they can damage the finish.
- Cartridge Inspection: If you notice a decrease in water flow, inconsistent temperature, or persistent dripping, the internal cartridge may need inspection or replacement. This typically requires turning off the water supply and removing the trim kit. Consult a professional plumber if you are unsure.
- Control de fugas: Periodically check for any signs of leaks around the valve body or connections, especially during routine plumbing inspections.
