The pressure test must be completed while the pipes are fully
accessible and before any screed or floor deck has been laid.
The pressure test is an important step to prove the integrity of the
system, ensuring nothing has been damaged during the install.

•
Ensure both isolation valves
are closed on the primary
circuit.
•
Open the flow valves and the
circulator isolation valve if a
mixing unit is fitted.
•
Increase the pressure to 1
bar. Hold this pressure for 45
minutes, while inspecting the
system for any leaks.
•
Increase the pressure to 6
bar. Hold this pressure for
15 minutes and continue to
inspect.
•
Ensure the system is full and
purged, see ‘Step 3’ page 18.
•
Connect a hydraulic pressure
tester to the flow arm fill/
drain valve and open it.
