How does the pool filter work?
Pool water is pulled to the pump then circulated from the pump into the filter where very small debris particles (pollutants and contaminants) are captured (filtered), and then the water travels through the heater and back into the pool.
There are three types of filters, sand, cartridge, and diatomaceous earth. Sand filters are the pretty common place in commercial pool applications due to their ease of cleaning and low overall maintenance. If you are pool owner with a sand filter that doesn’t seem to filter anymore, no worries, our SoCal Pool Guys technicians know how to remove the old sand, change the laterals, add the gravel and sand. We service a lot of commercial pools so we have had lots of practice.
Cartridge filters and diatomaceous earth filters are the most popular filters for residential applications here in Southern California. Pool water is forced through some type of sediment trap thereby removing debris particles. The cartridge filter passes water through a fibrous element, and a diatomaceous earth filter passes water through a thin layer of diatomaceous earth that is coated onto a grid.
Located somewhere (usually on the very top) on your pools filter is the pressure gauge. This gauge reads the ambient back pressure or resistance in your filter system to water flow. It is recommended that you have a properly functioning filter gauge to help display how dirty the filter is. At SoCal Pool Guys we baseline the filter, if the gauge reads 10 when the filter is clean the filter is probably ready for a filter clean at about a reading of 20. This is just a rule of thumb but not always an absolute. SoCal Pool Guys clean thousands of pool filters each year, we would love to clean yours!
