faq I Bravo <br />1) Sump ships from factory sealed under a continuous Vacuum test of 20"+ Hg. <br />2) Any breach in the wall, after sealed (Eg. penetration Fittings, lamination) is pressure/soap tested at 4 psi. <br />Page 2 of 3 <br />3) A 4 psi air integrity test is conducted after all laminations / fittings have been installed (prior to any hydrostatic filling) for one hour to allow <br />the pressurized interstice to acclimate, then level is recorded, and tested for another hour before recording result. <br />4) We also recommend that when DoubleWall sumps are felt overnight, that they have a factory -levet vacuum (20"+ Hg) applied to the <br />interstice, so that they can be inspected the next day. <br />5) If the sump is to be hydrostatically monitored, it is Hydra -Vac Filled. This is a Bravo -Exclusive installation procedure that pulls a 201+ Hg vacuum <br />on the interstice, then allows the interstitial fluid to flow in from a multi -gallon source through a ball valve. That isn't a test! You're right. The <br />Advanced Leak Detection Procedure (ALDP) depends on the sump being filled with our interstitial fluid first. The ALDP test pulls a high vacuum <br />on the interstice after it has been filled with liquid. With no acclimation necessary, the inspection can be done right after the Hydro -Vac filling <br />process. Any leaks in the DoubleWall sump will show up as traits of bubbles coming directly from the leak point(s), which can then be located and <br />repaired without wasting time guessing. <br />Bravo Systems has been producing DoubleWall Containment sumps since August 2003 and has continued to be the Leader in reliable Secondary <br />Containment equipment. Realizing that the last point of failure were the varied models of flexible penetration fittings, Bravo Systems engineered an <br />entire line of Tank -Spec Fiberglass Fittings (F -Series) that allow you to install and forget while being compliant at the highest level. The F -Series <br />provides unquestionable peace of mind as the fittings cannot deteriorate or fall since they contain no plastics, rubber, nuts/bolts, metals and do not <br />need to be filled with caulks or mechanical sealants. We are also the only manufacturer that provides an all -fiberglass conduit penetration fitting. <br />Take a look at our line of all -fiberglass fittings from the Products navigator at the top of the page. <br />View More <br />I Do I have to be certified to repair or test Bravo Float -Trip Mechanisms? <br />Do Bravo DoubleWall Sumps include Interstitial Fluid? <br />Do Bravo DoubleWall Sumps include all the necessary Fittings, Hoses and Manometers? <br />---- __ _ <br />[DoBravo Sumps include Vapor Shear Valves? <br />What do I do if my DoubleWall Sump gauge reads below 12" Hg (vacuum) or zero? <br />What types of repairs are allowed on Bravo B2000 shallow pans?
