Sorry for the nasty subject!! Our houseboat does not have a very large black tank. We like to go to Padre Bay so it's too far to go back and pump out mid week. Last year we went over to the floating pump station in Padre Bay but we could not get the pump to work. Another boat pulled up hooked up this sweet pump and pumped his black tank right out. I'm hoping someone can tell me what I need to buy and how to make it work so we can go over to the floating pump station mid week. Thanks so much!!
