Types Of Pool Filters

Different types of pool filters perform essential functions in maintaining clean water. Each filter type has unique cleaning frequencies and methods. Here’s a breakdown of the three main types of pool filters.

Cartridge Filters

Cartridge filters use a porous material to trap debris. They are efficient and easy to maintain. Clean these filters every 4 to 6 weeks, or when water flow decreases significantly.

  1. Check for debris: Remove the cartridge and inspect it for dirt and build-up.
  2. Rinse with water: Use a garden hose to clean off debris. Avoid using high-pressure water.
  3. Inspect for damage: Look for tears or signs of wear. Replace cartridges every 2 to 3 years.

Sand Filters

Sand filters contain a bed of sand that filters out dirt. They are durable and can effectively handle large volumes of water. Clean sand filters through backwashing when the pressure gauge reads 8 to 10 psi above the normal range.

  1. Start the backwash process: Turn the filter valve to the backwash position.
  2. Run the backwash: Let it run for 2 to 3 minutes until the water runs clear.
  3. Rinse the filter: Change the valve to the rinse position for about a minute. Then, return it to the filter setting.

D.E. Filters

Diatomaceous Earth (D.E.) filters offer superior filtration by using crushed fossilized algae. They can catch smaller particles but require more maintenance. Clean D.E. filters every 3 to 4 months or when the pressure rises more than 8 to 10 psi above normal.

  1. Remove the filter grid: Take out the grids and inspect them for damage.
  2. Wash with a hose: Rinse them thoroughly to remove accumulated debris.
  3. Reassemble and recharge with D.E. powder: Put everything back together and add a fresh supply of D.E. powder to ensure optimal filtration.

By understanding these filter types and their maintenance needs, you can ensure a clean, safe swimming environment. Regular upkeep contributes significantly to the longevity and performance of your pool system.

Signs That Your Pool Filter Needs Cleaning

When it comes to pool maintenance, recognizing the signs that indicate your filter needs cleaning makes a difference. Watch for the following indicators:

  • High Pressure Gauge Readings: If the pressure gauge shows a reading 8-10 psi above normal, your filter probably needs cleaning. Monitor this regularly to address issues promptly.
  • Cloudy Water: Cloudiness often signifies an overwhelmed filter. If your water lacks clarity, it’s time to check and clean the filter.
  • Debris Buildup: Noticeable dirt or debris accumulation inside the filter indicates it no longer operates effectively. Inspect your filter for any clogs.
  • Increased Chemical Use: If you notice the need for more chemicals to maintain water balance, it may stem from a dirty filter. Analyze your chemical usage for unexpected spikes.
  • Frequent Backwashing: If backwashing your filter becomes necessary more than once a week, consider a thorough cleaning. Excessive backwashing suggests your filter isn’t capturing debris well.
  • Poor Water Circulation: If pool jets aren’t delivering water as efficiently, your filter might be functioning improperly. Inspect and clean it to restore flow.

By watching for these signs, you can maintain your pool filter effectively, ensuring clear water and a healthy swimming environment.
