0 <br /> PREVENTATIVE MAINTENANCE <br /> Annually, inspect the flapper in the 71 SO to see that it is open by looking down the drop tube opening. Test the <br /> 71 SO drop tube seals with CARB procedure TP-201.1 D. If the drop tube seal passes testing, no further <br /> maintenance is required. If the drop tube fails testing, replace the drop tube seal with OPW P/N: H11931 M for 4" <br /> Tubes. Re-test the 71 SO drop tube with CARB procedure TP-201.1 D. The lower tube o-ring seal OPW P/N: <br /> H 14840M can also be replaced. If this does not correct the leak the 71 SO needs to be replaced. <br /> CAUTION: Do not insert any foreign object into drop tube if flapper is in the closed position. For example <br /> a tank level measuring stick. This will damage the valve and void the Warranty. ALWAYS check flapper <br /> location before"sticking"the tank. If flapper is in the closed position the tank is either over filled and you <br /> need to wait until the liquid level goes down or the 71 SO is damaged and needs to be replaced. <br /> 71 SO Performance Specifications: <br /> This Overfill Prevention Valve has been manufactured and tested to, and met, the following California <br /> specifications.
