Setup, Compatibility & Care

Setup

  1. Identify Pipe Size: Ensure you have the correct valve size (1.25" or 1.5") that matches your existing pipework.
  2. Horizontal Installation: The valve *must* be installed horizontally. Ensure the pipe run allows for this orientation.
  3. Directional Flow: Note the flow direction indicated on the valve body. Install the valve in the correct direction to allow water to flow away from the protected area.
  4. Secure Connections: Ensure all connections are watertight and secure to prevent leaks.

Compatibility

The McAlpine T28M-NRV is compatible with a wide range of pipe materials due to its universal connections.

Care

  • Regular Cleaning: This is crucial for maintaining the valve's performance. Access the valve via the top access point and remove any debris or sediment that may accumulate.
  • Inspection: Periodically inspect the valve for any signs of damage or wear.
  • Avoid Harsh Chemicals: Do not use aggressive cleaning chemicals that could damage the plastic components. Warm, soapy water is usually sufficient.
