37' 470 Allure here, also. I can adjist water level to 1/2" above; but it soon drains down. Box behind toilet has Corian cover that's glued on; so, cant enter from top of box wo risking breaking Corian. I CAN remove the 2 bolts on eaxh side holding toilet down. I assume it will lift away and expose the "too low" hose. What am i looking for and what do i do when i find it?
