UDC 3-4 failed due to a confirm leak from the top UDC wall electrical penetration. A troubleshooting test under the top electrical penetration was performed with passing result. Signs of past repairs could be identified. Need to repair and retest the UDC. Please see the enclosed picture. �'a,ra1 �°o�t��rs°PR��AsT If the entire depth of the UDC is not tested, specify how much was tested. If the answer to an\, of the questions indicated with an asterisk(*) is "NO" or "NA". the entire UDC must be tested. (See SWRCB LG -160)
