From Scummy to Sparkling: Your Guide to DIY and Pro Pool Filter Repair

Poolie Team: Jun 28, 2024

Crystal-clear water is every pool owner’s dream, but navigating the world of pool filters can feel like jumping into the deep end.

Relax! This guide will help you pick the ideal filter for your needs. From the convenience of cartridge filters to the unmatched clarity of DE filters, we’ll explore each filter type’s pros, cons, and maintenance needs.

Plus, learn how to spot the signs of a failing filter and tackle basic repairs yourself.

Find Your Perfect Pool Filter for Easy Upkeep

There are three main types of pool filters to consider: sand, cartridge, and DE (diatomaceous earth). Find your perfect match:

Sand Filters: Simple Yet Effective Filtration

Sand filters are popular with pool owners because they are simple, effective and user-friendly. They work by trapping dirt and debris as water passes through a layer of specially graded sand.

The key to keeping your sand filter happy is a process called backwashing. This basically reverses the water flow, flushing out all the trapped gunk. Backwashing is usually done every few weeks or when a pressure gauge tells you to. It’s an easy-to-do task and keeps your sand filter running smoothly for years.

Cartridge Filters: Convenient and Easy to Maintain

Cartridge filters are known for their convenience and top-notch filtration. They use pleated traps (like a giant coffee filter) to catch even tiny particles, giving you crystal-clear water.

Cleaning is a breeze. Just pop out the cartridges and hose them down every few weeks, depending on how much your pool gets used.

Cartridge filters are also cost-effective. The cartridges themselves are affordable and last a few seasons with proper care.

DE Filters: Superior Clarity Down to the Micron

DE (diatomaceous earth) filters are ideal for those who want the absolute best in water quality and are willing to invest more time and effort in maintenance.

DE filters offer the finest level of pool filtration available. They use a powder (made from fossilized algae) that coats a grid inside the filter, trapping even the tiniest particles down to a few microns. This level of filtering results in exceptionally clear water.

Maintaining a DE filter is more involved than the other two options. You must backwash it similarly to sand filters and add new DE powder. But for many pool owners, the unmatched water clarity is worth the extra effort.

Recognizing the Top Signs of a Failing Pool Filter

Spotting a failing pool filter early saves you time and money. Here’s what to watch out for to keep your pool sparkling clean and healthy:

Listen Up: Sounds That Signal Your Pool Filter’s Distress

Pool filters generally operate quietly. However, when something goes wrong, they start speaking another language—noise!

Here’s how to decipher their distress calls:

  • Grinding or Rattling: If you hear a grinding or rattling noise, it might mean something’s stuck in the impeller or the bearings are wearing out. Shut it down ASAP, remove debris around the impeller, and call a pro if the noise persists.
  • Humming or Buzzing: A loud humming or buzzing noise sounds like a motor issue. Often, this relates to an electrical problem, such as a failing capacitor or wiring issues. Turn off the filter and check the wiring for signs of damage, but if unsure, it’s safer to seek expert help.
  • Whistling or Squealing: Whistling or squealing noises are usually related to air leaks or pressure issues. Check your filter system’s seals and connections to ensure they’re tight and secure. Replace any worn-out O-rings or gaskets and reapply pool lubricant to seal properly.

Catching these sounds early can save your filter from premature replacement.

Seeing Clearly: Spot the Signs of a Faltering Pool Filter

Here’s where your eyes come in handy! Watch out for these visual cues that your filter isn’t performing optimally.

  • Cloudy Water: If your pool water looks milky or hazy, it’s a clear signal that your filter isn’t effectively trapping debris. First, check the filter media (sand, cartridge, or DE powder) and clean or replace it if needed. Additionally, inspect the filter for any clogs or blockages. You might need to deep-clean or backwash the filter.
  • Higher Pressure Readings: A higher-than-normal reading on your filter’s pressure gauge indicates a clogged filter. Perform a backwash or clean the cartridge. If the high-pressure reading persists, there might be deeper issues requiring professional attention.
  • Leaks or Drips: Visible leaks or water drips around your filter might signify that seals, O-rings, or other components need replacing. Inspect the equipment, tighten loose fittings, and swap out damaged parts to avoid bigger leaks and potential water damage.
  • Unusual Debris or Algae: Finding excessive debris or algae in your pool, even after running the filter, is a sign that the filter isn’t trapping particles efficiently. Clean and check the filter media. Consider running the filter for extended periods to ensure a more thorough cleaning.

By monitoring these signs, you can catch filter problems early and extend the life of your pool equipment.

When to DIY Pool Filter Repairs and When to Call a Pro

Pool filter maintenance can help prevent many issues, but repairs are inevitable. Here’s the lowdown on when to DIY and when to call a pro, saving you time, money, and frustration.

Self-Service Pool Filter Tips

With a bit of DIY know-how, you can resolve common pool filter issues such as:

Cleaning the Filter Media

  • Sand Filters: Turn off the pump, switch to “backwash,” and run for 2-3 minutes until clear water flows. Then, set it to “rinse” for another minute before switching back to “filter” setting.
  • Cartridge Filters: Pop out the cartridge and hose it down with high-pressure water, working from top to bottom. Soak it in a filter cleaner for deep cleaning, rinse thoroughly, and reinstall.
  • DE Filters: Backwash the filter as you would with a sand filter. After backwashing, add new DE powder according to the manufacturer’s instructions.

Checking and Replacing O-Rings

  1. Turn off the pump and release pressure through the air relief valve.
  2. Once depressurized, remove the filter cover and inspect the O-rings for cracks or wear. Replace any damaged O-rings.
  3. Apply a pool lubricant to ensure a good seal.

Fixing Leaks

  1. Find the leak source around the filter housing, connections, or valve.
  2. Tighten any loose connections and replace worn-out seals or connectors.
  3. If the leak persists, inspect the filter housing for cracks and consider replacing it if necessary.

By doing these repairs yourself, you can keep your pool filter running smoothly without waiting for professional help. However, knowing your limits is equally important.

Seeking Expert Pool Filter Help

Not all pool filter battles can be DIY victories. It’s best to hire an expert pool service during complex repairs or when a DIY approach can’t fix the issue.

Choosing the Right Company

  • Do Your Research: Look for companies with glowing reviews and high ratings. Ask pool-owning friends for recommendations, too!
  • Check Credentials: Make sure they’re licensed and insured. For added peace of mind, look for technicians who are certified by reputable organizations like NSPF or CPO.
  • Look for Experience: Find a company with a solid track record and familiarity with your type of pool and filter.

What to Expect During a Professional Repair

  • Initial Assessment: They’ll get down and dirty with a thorough inspection to diagnose the problem accurately.
  • Detailed Estimate: You’ll get a detailed breakdown of repair costs, including parts and labor.
  • Quality Workmanship: Professionals will use top-notch parts and fix things right for long-lasting performance.
  • Follow-Up: Reputable companies offer follow-up services to ensure the problem is fully resolved and prevent future issues.
