Fixtures

Fixtures, such as taps, faucets, showers, and sinks, are endpoints in your system design.

They represent the demand for water or drainage in the system and are essential for defining the overall load and flow requirements.

How to Add Fixtures

Step-by-step
  1. Select a Fixture:

    Use the drop-down menu in the toolbar to select the desired Fixture type.

  2. Placement:

    Rotate the fixture using the Arrow keys before placing it.

    Left-click on the floor plan to place the fixture.

    Press Escape to exit the placement tool.

  3. Connection Indicators:

    After placing the fixture, colored connections appear, indicating the systems that need to connect, such as:

    - Blue: Cold water

    - Red: Hot water

    - Orange: Warm water

  4. Auto-Connect:

    Hold Ctrl and select multiple Fixtures to enable the Auto-Connect pop up and tool.

    This will run pipes in the most direct route to connect the selected fixtures.

    It works best when there are direct and straight paths for the pipes to take between the fixtures

  5. Moving and Adjusting Fixtures:

    Fixtures can be Left-clicked and dragged to new positions after placement.

If connecting a non-standard system to a Fixture (e.g., Rainwater), enable Allow Other Systems to Connect in the fixture’s Properties.

Fixture Properties

  • Name: Assign a Name to identify the Fixture in the design.

  • Size and Rotation: Modify the size or rotate the Fixture after placement.

  • Height Above Floor: Set the Height of the Fixture in the Properties panel.

  • Connection Settings: Under tabs like Warm Water or Cold Water you can configure the system settings to Allow Other Systems to Connect. By default, Fixtures only connect to the designated system (e.g., Warm Water). Enable this option to connect alternative systems, such as Rainwater.

  • Continuous Flow: Add a Continuous Flow Rate if required, which contributes to the peak flow rate calculation.

  • Loading Units: Modify the Loading Units for the Fixture if the default values from the selected Peak Flow Rate Method do not suit your design.

  • Fixture Units: Modify the Fixture Units for the Fixture if the default values from the selected Calculation Method do not suit your design.

  • Minimum and Maximum Inlet Pressure: Specify the required pressure range for the Fixture. If the pressure falls below the minimum or exceeds the maximum, a Warning will alert you in the Results mode.

Right-click and Select Similar to modify multiple similar fixtures at once.

Troubleshooting Fixtures

  • Connection Issues: Ensure Pipes are properly connected to the colored connection points. Semi-transparent pipes and pipes with red circles indicate they are not fully connected.

  • Warnings: Check for Warnings about inlet pressure or Loading Units to resolve any calculation issues.

  • System Compatibility: If connecting a non-standard system (e.g., Rainwater), enable Allow Other Systems to Connect in the fixture’s Properties.

  • Reviewing Properties: Click on the Fixture to open its Properties and review all relevant details, including flow rates, pressure settings, and connections.

Overridden properties will cause the Fixture to be highlighted yellow for easy identification
