Hold down straps, if required, shall be in- <br />stalled in such a manner that they do not <br />damage the Tank Jacket. Use Strap <br />Cushions to insure that the steel straps <br />are cushioned and separated from the <br />Tank Jacket. <br />The method of anchorage selected shall <br />conform with state and local codes, <br />whichever applies. <br />(�) Final Testing <br />After installation and before final backfill- <br />ing to grade the Tank Jacket must be <br />retested to assure no damage occurred <br />during installation. <br />Perform an air pressure hold test to no <br />greater than 2 psi for a period long enough <br />to determine there are no leaks by a drop <br />in pressure. <br />Note: For tanks shipped with a vacuum, it <br />is not necessary to perform an in ground <br />test as long as vacuum was maintained. <br />9 Attaching standpipe <br />After all testing is completed and before <br />final backfilling to grade attach the Tank <br />Jacket Standpipe provided. The Standpipe <br />can be cut to the appropriate length re- <br />quired. Make sure that the cross fitting is <br />glued to the Standpipe, with water resis- <br />tant PVC cement. <br />Make sure the cross fitting is capped if <br />conduit is not installed. <br />M, Post -Installation Testin, <br />Should an air -pressure hold test be re- <br />quired to determine the containment in- <br />tegrity of the Tank Jacket in future years <br />then an Air -Pressure Bypass Adapter <br />should be used to bypass the cross fitting <br />conduit openings. This adapter is available <br />from Total Containment, Inc. <br />
