D - TESTING TKE BASE/COLLAR INSTALL <br /> Remove & save the SVA-BARB from the Gauge Assembly Schrader Valve (Refer to Step B.3) <br /> D.1 - Sweep away any gravel, dirt or debris around the OUTSIDE of the piping sump, where the <br /> tank collar meets the tank so that you will be able to see possible leaks. <br /> D.2 - Pressurize the interstice to 4 PSI and soap the fiberglass joint, inside and outside. If sump is <br /> holding, keep record. <br /> D.3 - IF ANY LEAKS ARE FOUND!! <br /> Look at edges and corners for pinhole leaks. For large leaks, consult factory. <br /> A: Locate leak point(s) and mark with marker so you can locate it / monitor it. <br /> B: Repair or reinstall doublewall penetration fittings according to your doublewall penetration <br /> fitting manufacturers' Installation / Maintenance Instructions. <br /> C: Abrade a 2" diameter area centered on the leak point until natural resin/fiberglass material <br /> can be seen. Dust with shop brush or compressed air and do not use shop towels or <br /> acetone on the abraded area(s). Then apply a 3-layer strip of 2" x 2" resin-saturated <br /> fiberglass mat squarely on the abraded area. <br /> D: Roll out any air bubbles with chamfer roller. Let cure. <br /> E: After cure, knock down fiberglass hairs, and apply another flow coat of <br /> resin only (Step C.14). Apply any extra resin to repaired leak point(s) while still wet. <br /> Let cure for a minimum of 4 hours @ or above 75° F. <br /> ALLOW ANY REPAIRS TO FULLY CURE BEFORE TESTING SUMP AGAIN <br /> DO NOT FILL DOUBLE WALL PENETRATION FITTINGS WITH FOREIGN MATERIALS <br /> D.3 - When the Fiberglass installation passes and is holding integrity, Install all your Double <br /> Wall Penetration Fittings per their respective Installation Instructions. Re-Install the SVA-BARB to the <br /> schrader valves. Do NOT install fittings on joints. <br /> IT IS RECOMMENDED TO SAND YOUR <br /> WALLS FLAT WITH THE T-FS-SAND-KIT <br /> DO NOT INSTALL PENETRATION FITTINGS ON OR NEAR FIBERGLASSED <br /> JOINTS. CONSULT THE FACTORY. <br /> DA - After the Fittings have been installed and the sealant/adhesive has fully cured, pressure/soap <br /> test all fittings at 4 PSI. <br /> NOTE: Vulkem Sealant must cure Overnight. This is used with Bravo Systems Flexible <br /> Penetration Fittings. <br /> D.5 - When the Penetration Fitting installation passes and is holding integrity, You can begin <br /> installing pipe lines at this time or later. <br /> 11 ii-B401-DW-SP-10A <br />
