Pool Filters

Your choice of swimming pool filter plays an extremely important part in the overall health of your pool water and your pool system. The filter works by trapping small, particles, dirt, and debris (which have not been stopped by the skimmer) within the sand or glass located inside the filter. The clean water then returns to the pool via the pump, in some cases people choose to add additional cleaning methods such as UV sterilisers which can help to reduce the level of chemicals needed. The sand or glass is usually referred to as filter media. As the media collects the debris, the water struggle to pass through it causing a build-up in pressure which can be seen on the pressure gauge when the indicator reaches the red. When this happens, the filter must be backwashed, this is when the flow of the water is reversed using a multiport valve so that the water is taken from the pool, through the filter, where it can remove the particle build-up and out into a drain. Filter media will usually last between 5 to 7 years, after this, it is advisable to change the media to keep your system working well.
