Here's my program to help deal with stuck float switch but it should help in your situation too. My ato pump comes on after every 4hrs and allow to run up to 20sec only (my pump needs less than 20sec to topoff but your pump speed might vary). If the pump runs for more than 20sec, I will get a text message telling me it exceeded the time limit which probably means I have a stuck float switch or in your case a loose hose. Hope this helps.
