How do you winterize an in-ground saltwater swimming pool?

With the onset of the cold weather, you will need to winterize your gunite pool. Backwash the pool filter. Detach the pump and filter to drain any left over water. Drain the pool heater. Remove return jet fittings, the skimmer basket and pipes. Blow air through the system until bubbles appear in the water and cap off the fittings. Put an empty twenty ounce plastic bottle in the skimmer basket to compensate for freezing and thawing. Remove water from the main drain line and cap it. Remove ladders and floats. Lower the level of the water beneath the tile line.
