PBA Tip of the Day brought to you by Alex Fleshman with Ironman Pool Service, LLC (623) 221-5011.Your swimming pool installation is essentially a large basin of water that is consistently exposed to a variety of elements. In order to keep the water safe for human exposure, you will need a functioning filter. A cartridge filter is one type of swimming pool filter that removes contaminants from the water. Although cleaning your cartridge filter with a regular hose can be effective in some cases, chemical cleanings can be even better. A dirty cartridge filter can make the water unpleasant and even unhealthy for swimmers. Contact Alex today to discuss filter cleaning!
