Today I went to replace the short hose on the discharge section of the pump---only to discover that the longer and wider hose running from the sump on the outer tub to the pump was already leaking. When I went to look at it a little closer, it broke off in my hand. Looks to me like I will have to remove inner tub to replace it. Anyone been there done that? Any light you can shed on the subject will be greatly appreciated. -Steve
