Skimmer
A swimming pool will have a skimmer located on the side of the pool . The skimmer is the point at which water is drawn from the pool by the pump and is key to proper circulation. The skimmer is designed to trap floating debris from the water surface in a basket . The basket can be removed from the skimmer and emptied.
The skimmer basket will also trap debris that is vacuumed from the floor of the pool by a manual cleaning vacuum or some automatic pool cleaners. A plate is inserted into the skimmer over the basket in order to create a suction point for the manual cleaning vacuum or some automatic pool cleaners. You should check the skimmer basket regularly and empty debris from it so as not to impede the operation of the pump.
Pump
Once through the skimmer, the water travels along the suction line to the pump itself. At this point there is a basket built into the pump to trap any debris that managed to get through the skimmer basket. This is called the hair and lint basket and is designed to trap finer particles of debris. Again, this basket is removable and should be cleaned regularly.
Return
The clean filtered water will now return to the pool via the return line, but first it will normally be sanitized. One of the most common systems is a salt chlorinator. The salt chlorinator cell is installed in the return line and produces chlorine from the salt water by means of electrolysis. Other sanitizing systems are also available.
The clean filtered sanitized water is now on the way back to the pool via the return line. The return line is usually divided at this point into the water returns to the pool via several return jets. It’s a good idea to have one of these jets adjusted to move surface water toward the skimmer and one adjusted toward the floor to move any debris on the floor. Thus, the cycle is complete and if you run your filtration system the correct amount of time according to the size of the pool, usage and temperature conditions you should have very few problems. a paragraph.
