My Sump is in the basement so I just had a t come off with a ball valve. I can literally dump a new 5 gallon bucket of saltwater in my sump put it down next to the sump, turn the valve open and fill it to the same level that the new salt water was at. It takes me about two minutes to do a water change. I just had to pick up the old water and dump it outside cuz I don't want that going in my septic system. For anybody that doesn't know saltwater eats the septic tank they're made of concrete.
