Use care when drilling through filament wound sump riser <br /> tubes . Do not force hole saw, for FRP sumps , cut hole slowly , half way through from both <br /> sides ( inside and out ) to prevent fraying of filament strands . Always use correct size hole saw <br /> or drill . Do not fiberglass bond piping or conduit directly to FRP sumps as this will not allow <br /> any movement , due to ground settling , back- fill , etc . <br /> BACKFILL REQUIREMENTS : <br /> Sufficient backfill must be used below and along the sump side to provide support and <br /> protection against ground movement . <br /> TEST PROCEDURES FOR SINGLE WALL . <br /> After the sump to tank fitting is completed , you shall test the integrity of your seal . This is <br /> important to insure that the sump riser tube / tank bond will not allow any contained fluid to <br /> leak . Check with local regulations for required testing procedures . A common test procedure <br /> is to fill the sump with water after the sump / tank bond has completely cured , usually <br /> overnight , and observe bond seam for any leaks . <br /> ADDITIONAL INSTALLATION REQUIREMENTS - STATE OF FLORIDA ONLY : <br /> Leak Test Requirement : <br /> 1 ) a . Fill entire sump within 4 to 6 inches of top . <br /> b . Observe water level for a minimum of 3 hours . <br /> c .
