I'm not a potty tech, but just had my Aquajet unbolted to clear some crud out of the water flush mechanism in back and noticed that there is some kind of pressure relief valve at the top. It has a hole with black rubber grommet underneath. It would release water when hooked to the hose under pressure. Perhaps yours is leaking under abnormal pressures?
