The Messana panel pressure testing procedure is a crucial part of the Messana installation process. It plays a significant role in ensuring that all connections within the system are correctly installed and free from leaks. Moreover, this procedure is not only mandatory but also necessary to validate the warranty provided by Messana.
To ensure the integrity of the system, a high-pressure burst test is conducted, and the results must be approved and signed off by an authorized third party (typically a local building inspector).
High pressure burst test ( up to 100PSI)
The intent of this test it to make sure all fittings are completely connected and leak free.
Open all the supply and return leader ports on the manifolds so that each port serving the Messana active panels is fully open. This is a vital step and must be done otherwise the test results can be false.
NOTE: Do not pressurize the manifold with the closed loop. It is essential to have at least one loop open during this procedure to prevent the manifold from locking.
- CONNECT THE PRESSURE GAUGE
Identify a suitable test point where you can connect a pressure gauge. This can be a drain valve or a dedicated test port.
Attach the pressure gauge to the test point using a suitable adapter or connection.Ensure that the gauge is properly secured and tightly connected to prevent any leaks.
Perform a pneumatic (air) test before the hydrostatic (water) test to prevent water spillage on the job site.
Slowly open the valve connected to the air supply to allow air to fill the system.
Gradually increase the pressure to the recommended operating pressure for your hydronic system.
Monitor the pressure gauge as you increase the pressure, ensuring it rises steadily without any sudden spikes or drops.
Monitor the pressure gauge for a specific duration, typically for 20 minutes, to observe if the pressure remains stable.
Any noticeable drop in pressure during this period may indicate a leak in the system.
Walk around and listen for any leaks, this may require time on the project when there are no other noises. It is a good idea to stop at 50 psi and walk the job to listen for leaks.
If no leaks are found, then continue filling the system to 100 psi.
The pressure of 100 psi must be achieved to ensure that any fittings where the piping was not fully inserted will be found and fixed. Make note of the time and pressure then document.
NOTE: Always exercise caution while pressurizing the system, as excessive pressure can lead to damage or failure.
- PRESSURE HOLDING
Once the system reaches 100 PSI, close the valve connected to the supply or stop the pressurization process.After 20 minutes come back and check the gauge reading and document the time and pressure again.
- LEAK DETECTION
If you notice a pressure drop during the pressure holding period, you’ll need to identify the source of the leak.
After finding a leak, replace or fix the problem following the Ray Magic NK® installation manual (how to disassemble a RM 3-way fittings) and fix the problem using a coupling in the 8mm tubing.
If the leak is on the backbone pipe (16mm), we suggest replacing the entire panel.Repeat the operations 3, 4, and 5 using water instead air.
- RELEASE THE PRESSURE
(maintain 50 psi of water pressure)
After the high-pressure burst test is complete, you can reduce the pressure down to the 50s.
NOTE: It is recommended to maintain a water pressure between 40 and 50 psi throughout the duration of the drywall installation.
