The component you mention is a one-way valve that prevents backflow from the black tank. If leaking, like mine was, it should be replaced, and definitely NOT eliminated. If you eliminate it, you risk contaminating the water source used for the flush. They are not expensive, and mine took about 15 minutes to replace (located under bathroom sink). Some hard to reach locations might require more time, but you definitely should do the replacement, or have someone do it for you.
