In this Outdoor Recreation video tutorial you will learn how to pump out the waste on your boat for winter. This video is from LIBoatersClub. Take your boat to the waste disposal area and secure it. Remove the cap from the waste tank. Be careful not to drop the cap. Operating the waste disposal unit ashore is very easy. Just switch on the pump, take in some water in to the hose and then attach the hose to the out let on your boat. Hold it tight and open the valve. It will suck out all the waste from the tank. You can observe the glass window on the hose to make sure that all the waste is pumped out. Then shut the valve and switch off the pump. That's it, your boat is clean!
