Filter cartridge housings are an essential part of any pool system. They trap particles that can contaminate water. Most cartridge filters come in tall cylinders made of dirt-trapping fibers that are housed inside a pressurized tank. A closure plate separates the cartridges and forces water through them. Once filtered, the water is discharged from the filter through a collector manifold and then back into the pool.
While these units are able to handle larger amounts of debris, they will require cleaning a few times a season. Generally, cartridge filters will need to be replaced every 18 to 24 months. A new cartridge filter will have sharper pleats, which will maximize filtration area. Typically, this will require a replacement every 18 to 24 months. If you are concerned that your cartridge filter is getting too old, you can also hose it off to remove large debris.
A large safety concern is a properly functioning air relief system. A pool filter is designed to handle pressure from the water. Unfortunately, air compresses very well, and the air can build up to a pressure that no pool system can handle. If the internal air bleed off valve is damaged or missing, this can be a dangerous situation. If the internal air bleed off system is not functioning correctly, it can lead to a fire.
One of the major safety concerns with a cartridge filter is the air relief system. The air relief system is meant to relieve the pressure created by the water. But the pressure from air builds up to a level that a pool filter is not designed to handle. If you fail to check the air bleed off system, you could create a situation that is extremely dangerous for you and your family. Therefore, you should never try to fix or replace a cartridge housing without consulting your customer first.
Another important aspect of a cartridge filter is the end cap. End caps protect the filter media from dirt and other debris that would otherwise cause it to malfunction. A cracked end cap may also be a sign that your pool filter cartridge needs replacing. If the end cap has cracked, you should call the manufacturer immediately to prevent further damage. If this happens, contact the customer to ensure that a replacement element is available. The next time you install a new element, make sure you inspect the pool's filter cartridge housing for cracks.
Once the filter cartridge housing has been opened and closed, inspect the air relief system and the cartridge filter elements for signs of wear. If you suspect that the air relief system is damaged, the problem can be a sign that the filter cartridge is not working properly. If the filter element is not working properly, contact your technician immediately to have it repaired or replaced. This will save you time and money on the future. A malfunctioning pool filter is no fun at all, so be sure to pay attention to the quality of the water and filtering system.
