Purpose of hose test or water leakage test (spray) is to provide quality assurance and diagnostic field water check method for installed curtain walls, exterior windows and doors. Spraying water in a specified way is a quick and easy way to check whether the installed system is vulnerable to leakage. TTS is equipped with all facilities to conduct hose test at site for installed curtain wall exterior windows and doors as per AAMA 501.2. We are an approved agency for conducting this test for almost all commercial projects. The spray system delivers water uniformly against the exterior surface of the sample. The hose test should be employed periodically during construction as a check on quality of work.
