0�) BRAVO SWRCB Requirement for VPH Communication <br /> PROBLEM SOLVED <br /> VACUUM METHOD ' <br /> TANK SUMPS ! ' w Fluid Level Rises <br /> 1. Once the test has concluded, secure the cap <br /> back on the manometer. <br /> If manometers are completely filled with <br /> interstitial fluid, use the alternative testing <br /> method shown below. <br /> Remove cap from primary manometer, <br /> slip on the rubber reducer and clamp it to <br /> the manometer tubing. <br /> E'.. Take the vacuum assembly and place the <br /> full coupling in the reducer and clamp it so that <br /> it is sealed, as shown below. <br /> Interstitial fluid may rise out of the T-890 VPH COMMUNICATION KIT <br /> manometer after the communication <br /> test has been performed due to the <br /> pressure over time. This will depend <br /> on the level of the interstital fluid <br /> and temperature change. <br /> i <br /> C Pull vacuum using the hand operated vacuum <br /> pump provided in the <br /> T-890 VPH COMMUNICATION KIT. <br /> If there is communication, a sudden drop in fluid <br /> level will be evident in the atmospheric manometer. <br /> 2929 Vail Avenue,Commerce CA. 90040 1 Office: 323.888.4133 Fax: 323.888.4123 www.sbravo.com <br /> 2. <br />
