- Choose a nylon bristled brush at least 24 inches long to cover a wide swath on each pass for efficient brushing. If your pool has curved corners and a curved transition from walls to floor, choose a brush that curves up at each end to match the pool's contours. If the corners are sharper, and the transition from walls to floor is closer to a 90-degree angle, choose a straight brush with no curves on the ends.
- When preparing to brush your pool, set the pool valves so that all the water is pulled in through the bottom intake, called the main drain. Close the valves to the skimmer(s) completely. Net out all floating debris on the surface of the water, and net large debris, such as leaves and twigs, off the bottom before brushing. Pick up debris that 's too large to be pulled in by the main drain.
- Attach the brush to your telescopic pool pole and, beginning at one corner of your pool, brush the walls all the way around. Place the brush just below the water line and brush straight down in one continuous motion all the way to the pool floor. Overlap strokes slightly as you work your way around the entire pool, covering every section of the walls. Brush both the horizontal and the vertical surfaces of the pool steps, including the crevices of inset steps.
-
After allowing the debris from the walls to settle to the bottom for a few minutes, begin at one corner of the pool floor, on the shallow end, and brush everything toward the main drain in smooth, even strokes, working your way across from one side of your pool to the other. Jerky, choppy strokes only stir things up. The suction from the main drain will pull the dirt and debris in, removing it from the pool.
Once you've completed brushing, turn the equipment off and clean the pump's hair and lint pot to remove the solid debris pulled in through the main drain. Reset the pool valves to normal operation with 75 percent of the water flowing through the skimmer(s) and 25 percent flowing through the main drain.
