A Pool’s Filtration System

Know your pool Inside and out

Your pool’s filtration system has many parts. With proper pool maintenance service, these parts are less likely to breakdown and will last longer. Here are some of the terms you should know when it comes to your pool’s filtration system.


Multiple skimmer drains are located around the top of the pool. Skimmers draw water the same way as the main drains, but they suck only from the very top of the pool.


These ports attach to pool vacuum cleaners, which work something like ordinary vacuum cleaners except that they suck water instead of air.


Water flows to the filtering system through two or more main drains at the bottom of the pool usually located on the lowest point in the pool.


The water pump circulates the water. Your motor is known as the dry end of the filter pump. It drives the impeller, which moves the water from the various drains through the filter and back out to the water inlets.


A device used to remove particles suspended in the water by pumping water through a porous substance or material.


A pool heater works by burning fuel to create heat, which is then passed through a heat exchanger and onto water pulled from your swimming pool. The water is then reintroduced to the pool, raising the overall temperatur

Water Chemistry


(stabilizer) level is too high. This level is ideally kept under 150 ppm. When it rises to the 150ppm or higher level it neutralizes the chlorine in the pool. The only way to correct this problem is to drain the pool water, which should be done every 2 years, on commercial pools.


Are present in the pool water. Phosphates are food for algae and come from living matter. If your pool gets a volume of leaves or other living debris deposited in the water the phosphate level will be too high. This can be corrected by adding Phosphate treatment to the pool water, which is available in our store, and eliminate the phosphates.


In the water. This develops over time through normal usage and the water literally gets so full of dissolved solids that it cannot hold the chlorine effectively. The easiest way to correct this is to drain the pool water. PH level is high. If the PH is too high it does not allow the chlorine that is present to be active. Use Muriatic acid (not more than a quart at one time) to lower the PH level.
