Union Street <br />Stockton, CA 95205 <br />RE: San Joaquin County Corporation Yard <br />Primary Underground Piping <br />T#X Jo�i S -W852 <br />.EEb. 09 1999 07:30AM P2 <br />4P <br />Via: Hand -Delivery <br />As a result of discussions between the Public Works Department and the Health Department <br />regarding the fiberglass piping installation, it was determined that the project will only be <br />allowed to continue once one of two actions are taken to rectify the concerns of the above <br />Departments due to the appearance of the installation. <br />The quantity of glue at the joints concerns the departments and does not appear to be in <br />compliance with the manufacturer's installation instructions. The two actions that will satisfy <br />the County inspectors are as follows: <br />Qpg„ on #1: Perforin a hydrostatic cyclic test as recornmended by A.0. Smith in <br />Manual #B2160, dated July 15, 1996. During discussions with the Health Department <br />the following issues were clarified: <br />a) The impact valves at dispenser sumps are to be removed and the flex <br />connector capped prior to testing system, <br />b) Test to be run to 375 psi and in conjunction with A.O. Smith Test <br />Procedure (Section 1-7-2 of abovc-referenced manual). <br />c) Test shall be run on 1) Gasoline Primary, 2) Diesel Primary, and 3) <br />Diesel Satellite product lines. The cyclic pressure test is not required on the <br />vent and vapor recovery lines. The pressure is to be kept on each individual <br />system without pressure fluctuation for one hour prior to system obtaining <br />approval, <br />d) Once cyclic pressure is complete and systems are deemed tight, the <br />impact valves shall be reinstalled, and the air pressure test per the project - <br />approved plans would need to be completed prior to final primary system <br />approval. <br />
