Pressure Testing

To ensure the system is installed correctly and operating properly,

it is important to pressure test the system. There are several options

to pressure test a system, including air and water. However, air provides

a much more rigorous test.

1. To ensure all valves are working accurately, open and close all valves

twice. Make sure all manifold isolation and flow valves are open.

Note: Manifold Supply and Return Ball Valves should be closed

during the pressure test procedure.

2. Connect the Uponor Manifold Pressure Test Kit (E6122000) or other

pressure test device. Uponor recommends a test pressure of 3 times

the operating pressure, or at least 40 psi.

Note: Maximum pressure when testing with air should not exceed 100 psi.

3. Visually check for leaking and monitor the pressure for the duration

specified by local code. (A typical pressure test can range from

2 to 24 hours.)

4. If there is no reduction in pressure, the system is regarded as sealed.

5. After completing the pressure test, set the operation pressure.
