Pressure Test

A hydrostatic (water) test of the concealed radiant panel used to determine the “tightness” and “leak-free” condition of the tubing. The test should always result in “no loss” of the pressure and be performed in accordance with Code-approved procedures. The introduction of helium, nitrogen, oxygen, or other type of air to pressurize the system for testing is not an acceptable test and will likely result in inaccurate conclusions.
