Patent

CA 2639600

The present invention discloses a testing apparatus and a method for testing valves used in municipal water distribution pipeline networks, particularly air- release/vacuum-breaker combination valves. The testing apparatus comprises a cylindrical reservoir to which the valve to be tested is connected. Testing is performed with water at the desired pressure, with compressed air, with vacuum and/or with a combination thereof. A determination as to a test valve's operational state is made based on the presence or absence of gas and liquid discharges and/or suction noises from the outlet, inlet, seals and joints of the valve.
