Secured Test Boot on Secondary Pipe in STP Piping Sump, and filled UDC to test level. <br />This method allows Test Fluid to fill UDC and Secondary Pipe simultaneously. <br />Secondary Pipe Test Boot at STP Piping Sump opened at end of testing to allow all Test Fluid to drain. <br />' If the entire depth of the UDC is not tested, specify how much was tested. If the answer to any of the questions indicated with an <br />asterisk (*) is "NO" or "NA", the entire UDC must be tested. (See SWRCB LG -160) <br />
