How it works

Three steps from installation volume to report.

Step 1

Calculate the installation

Choose the meter, installation type and operating pressure, then add each pipe section. Tivy totals the installation volume and classifies the job as UP1, UP1A or UP1B.

Step 2

Run the right test

Use the guided tightness, strength and purging workflows with the values Tivy needs, in the order you need them on site.

Step 3

Get the report

Generate a professional PDF report from the job details and share it before you leave site.
