Filter Maintenance
A clean filter effectively removes dirt, debris, and contaminants from the water, ensuring your swimming pool remains clear and safe for swimming.
Types Of Swimming Pool Filters
There are three main types of swimming pool filters, each with its own advantages and maintenance requirements.
Cartridge Filter
These use a replaceable filter cartridge made of fibrous materials to trap particles. They provide finer filtration than sand filters and are cleaned by removing the cartridge and hosing it down.
Sand Filter
These use sand as the filtering medium. Water is pushed through the sand, which traps debris and particles. They are easy to maintain and clean by backwashing.
Diatomaceous Earth (DE) Filter
These use a powder made from fossilized remains of diatoms as the filtering medium. DE filters provide the finest filtration, capturing very small particles. They require regular backwashing and recharging with new DE powder.
Benefits of Routine Filter Cleans
Improved Water Clarity
Clean filters effectively remove debris and particles, resulting in clearer and more inviting pool water.
Enhanced Hygiene
Proper filtration helps eliminate harmful bacteria, algae, and other contaminants, making the pool safer and more hygienic for swimmers.
Increased Efficiency
Clean filters ensure optimal water flow, reducing the workload on the pump and filtration system. This can lead to energy savings and longer equipment life.
Balanced Chemistry
Clean filters contribute to maintaining the correct balance of pool chemicals, making it easier to manage and ensuring a comfortable swimming environment.
Longevity
By reducing strain on the pump and other components, regular filter cleaning can extend the life of your pool equipment.
Aesthetic Appeal
Clear, clean water enhances the overall look of the pool, making it more attractive and enjoyable for users.
How Often Should the Swimming Pool Filter be Cleaned?
Swimming pool filters should typically be cleaned every 4-6 weeks, depending on the usage and the type of filter. However, this can vary based on factors such as pool size, usage, and environmental conditions. It's also a good practice to check the pressure gauge; a rise of 8-10 psi above the normal operating pressure is a sign that the filter needs cleaning.
What to Expect During a Filter Clean
Power Down System
The pool pump and filtration system will be turned off to ensure safety and prevent water from flowing through the filter during the cleaning process.
Pressure Relief
The pressure valve on the filter will be opened to release any built-up pressure within the system.
Remove and Clean Filters
Cartridge Filters: The cartridge will be removed from the housing for cleaning. The cartridge will be hosed down to remove dirt and debris, and soaked in a filter cleaning solution if needed.
Sand Filters: The sand may be stirred and agitated to break up clumps, and backwashing will be performed to flush out debris. The sand will be rinsed with water, and if necessary, replaced if it has become too dirty or clumped.
DE Filters: The DE grids or fingers will be removed from the housing for cleaning. The DE grids will be hosed down to remove old DE powder and debris. Fresh DE powder will be added to the system after reassembly.
Filter Inspection
All filter components will be inspected for any signs of damage or wear. If any parts are damaged, they may need to be replaced.
Reassembly + Restart
The filter media will be placed back into the housing, and the housing will be securely closed. The pool pump and filtration system will be turned back on, and the pressure will be monitored to ensure everything is working correctly.
Leak Check
Your pool technician will check the system for any leaks around the filter housing and connections.
Backwashing - If Applicable
For sand and DE filters, a backwash cycle may be performed to ensure all debris and old media are flushed out of the system.
