How Often Should You Backwash a Pool Filter?

Maintaining a clean and functional pool hinges significantly on the upkeep of its filter system. Backwashing your pool, a principal maintenance technique, enhances a pool filter's efficiency by clearing out accumulated debris. How often should you backwash a pool filter varies based on filter type and brand, suggesting a tailored approach for each pool owner.

What is Backwashing?

Backwashing is a process where water flows backwards through the swimming pool filter, to remove trapped debris. This prevents blockages and ensures the filter continues to operate effectively, keeping the pool water clean and swimmable.

Factors Affecting Backwashing Frequency

Filter Type

• Sand filters: These filters trap dirt and debris using fine sand media. Backwash your pool every few weeks or when the pressure gauge reads 8-10 psi over the normal level.
• Cartridge filters: These filters don't use backwashing. Instead, you remove the cartridges and rinse them with a hose every few weeks.
• Diatomaceous earth (DE) filters: A DE filter uses a fine powder to catch particles and usually needs backwashing more often than sand filters—typically after a 1 psi increase over the clean pressure.

Pool Usage

The more your swimming pool is used, the more you need to backwash it. Public pools usually backwash every week because of heavy use, but private pools might only need it every two weeks.

Environment

External factors like trees, pollen, and weather conditions can increase debris in the swimming pool, necessitating more frequent backwashing. Pools in leafy or dusty areas may require you to backwash water more often to maintain clarity and hygiene.

Brand Specific Recommendations

Different brands of pool filters might suggest varying schedules for backwashing. Check out Atomic Filters’ pool and spa filter collection online for detailed maintenance tips for different brands and types of filters.

Step-by-Step Guide to Backwashing Your Filter

1. Turn off the pump: Ensure the pool's pump is off before starting the backwashing process to avoid damage.
2. Set the valve: Set the backwash valve to 'Backwash'.
3. Reactivate the pump: Turn on the pump and let it operate for around 2 minutes, or until the sight glass shows clear water.
4. Rinse: After backwashing, switch the filter valve handle to 'Rinse' and run the pump for about 30 seconds to stabilize the sand bed.
5. Reset: Return the filter valve to its normal position.

Maintaining Your Pool Filter Between Backwashing

Staying on top of your backwash pool filter routine upkeep is crucial. It reduces the frequency of necessary backwashing and enhances the filtration system’s efficiency.

Here are the steps to follow:

• Check the pressure gauge often: Keep an eye on the pressure gauge. A high pressure reading signals a blocked filter medium needing cleaning. Don’t delay—regular inspections can prevent bigger problems.
• Clean baskets and traps regularly: Debris not only clogs the filter; it can also obstruct water flow before reaching the filter. Frequently empty skimmer baskets and traps, ideally every week.
• Inspect for leaks or damage: Look over the filter system for any signs of filter leaks or wear and tear. Identifying these issues early can help avoid larger problems later on. Most filter leaks occur around the drain plug, so ensure this part is tightly sealed.
• Backwash only when needed: Avoid the temptation to backwash too frequently. It's not just about following a schedule—only backwash when the pressure gauge tells you it’s necessary.
• Keep the pool area clean: Keeping the surrounding area clean means less mess in your pool. Regularly sweep away leaves, prune surrounding vegetation, and maintain cleanliness to minimize debris.
• Use a pool cover: Cover your pool when not in use. This easy step prevents dirt, leaves, and other debris from entering, which lessens the burden on your filtration system.
