condensate). If found, remove such materials prior to air testing. 4.1.4 Never tamper with or tighten any fittings (i.e., connections, bolts, hoses) while component is under any pressure. 4.1.5 Never tighten connections that are under pressure. If a leak develops , you must depressurize to a safe level and then re-tighten.

Guideline for Flow and Pressure Testing of Hydrants
www.joiff.com6.1.2 The hydrant valve is partially opened to allow a small amount of water to flow and expel air from the equipment. The pressure relief valve on the blank cap is closed and the hydrant valve is fully opened. 6.1.3 Whilst under pressure, all joints are visually inspected for signs of leakage. Leakage’s should be reported.
