Is it leaking where the clamp is? If so, the clamp might be faulty or the hose may have a leak in it. Is it where if hooks to the pump? Or is it between the pump and the tub? You might try replacing the clamp and then inspecting the hoses. If there is a leak in the hose, you might be able to cut a small section of it off then reclamp it.
