No. Using water or compressed air are effective tests for a pressurized system, but are not appropriate for a system with connections and valves designed to work under vacuum. It is very important not to test with water. Water in a vacuum system must be completely removed in order to restore the full vacuum capacity of the system, since water in the lines will evaporate when vacuum is applied and limit the ultimate vacuum of the system to the vapor pressure of water at room temperature (24 mbar/18 Torr) until all of the water is removed. This could take two days of continuous pumping.
