Importance of Brushing Your Swimming Pool
Many p.eople think.."I have an automatic pool cleaner, my pool is kept clean, why do I need to brush?" I will answer that common question. first and foremost you want to preserve the condition and appearance of your pool, after all you have spent a lot of money in having it built or re-surfaced. You will want to protect that investment. Dirt and debris can adhere to the pool surface. Failure to brush the pool can lead to stains.
As part of your regular maintenance you should spend about 10 - 15 minutes twice a week brushing your pool walls, steps and bottom. Brushing does not require a lot of energy or strength. Brush strokes are slow and smooth. You will begin at the tile line and brush down the sides of the walls. Each stroke should overlap the previous stroke to ensure proper and complete coverage. You may continue your stroke down the bottom always directing the dirt toward the main drain. It is best to begin in the shallow end and work around so you complete at the deep end. This is so you are pushing all dirt and debris towards the main drain. You may want to brush all the walls of the swimming pool, then the bottom. The process doesn't really matter except that you want to cover the entire surface.
Prior to brushing you will want to open the main drain valve at the equipment and close the skimmer valve, or at least partially close it so there is good suction in the main drain to collect the dirt. Using a nylon bristle brush is recommended. Once you have finished brushing all the sides, steps, and bottom you may then go back to your equipment on adjust the valves so the skimmer is open and the main drain is only partially open - or whatever settings you are use to.
Please note** Do NOT use a wire brush on vinyl, painted or fiberglass pool surfaces.
If you swept quite a bit of dirt into the filter be sure to clean your filter after brushing or when the pressure on the pool filter tank reaching 10-12 pounds above normal operating pressure, See: How to Clean a Pool Filter Cartridge, or follow the manufacturer's instructions.
