Keeping the sand filter of your swimming pool clean is necessary along with the proper chemical balance to have crystal clear pool water. Keeping your pool filter clean also prolongs the life of the pool pump, piping and the filter sand itself. A dirty or clogged pool filter increases the work load on your pool pump and increases the pressure in the pipes which can cause the pipes to fail and leak and the pump to burn out. Not to mention a dirty filter leaves more dirt and debris in your pool. The best indicator of the effectiveness of your pool sand filter is the filters pressure gauge. The gauge or is located on or near the filter housing. Whenever the pressure increases 8 to 10 psi (pounds per square inch) from a base line established when the sand filter is back flushed and clean. How often you need to clean your pool sand filter will depend on a number of factors such as if your pool is screened, how long your swimming season is, if there are trees near the pool or even if there is construction in the area that increases dust and dirt in the air. The manufacturer instructions that came with your sand filter should be followed whenever you service your filter. If you do not have the manufacturers instructions because they have been lost, misplaced, or the pool and filter were already present when you moved in to your home, don't despair, most companies provide instruction manuals that are downloadable from their websites or available by mail. If they are not available the following instructions, which are general in nature, will work for most sand filtering units.
