Pre-Season Checklist: Pool Filter Maintenance

Owning a pool is a joy—but keeping it clean? That’s where the hard work comes in! Pre-season maintenance is the key to kicking off a smooth and worry-free pool season. And guess what? It all starts with your pool filter. Your pool filter is the unsung hero of the swim season, tirelessly working to keep your water clear and healthy. But like all heroes, it needs a little TLC to keep doing its job.

This guide will walk you through everything you need to know about prepping your pool filter before swim season. We’ll cover the different types of filters, step-by-step maintenance instructions, troubleshooting tips, and advice on when to call a pro.

Understanding Your Pool Filter

Before jumping into pool filter maintenance, it’s important to know what kind of filter you have. Not all filters operate the same way, and each requires specific care.

Sand Filters

These are the budget-friendly workhorses of the pool world. Water flows through silica sand, trapping dirt and debris. Sand filters are durable and easy to manage, but they may not catch the smallest particles.

Cartridge Filters

If you value effectiveness and eco-friendliness, cartridge filters are a great option. They use folded polyester as the filtration medium and require less water to clean since they aren’t backwashed. Ideal for capturing finer debris.

D.E. (Diatomaceous Earth) Filters

The gold standard of pool filtration! These high-performance filters use fossilized diatoms (a fine white powder) to trap microscopic particles. They’re the most effective, but are also the priciest and require a bit more effort to maintain.

Sand Filter Maintenance Checklist

Maintaining your sand filter might sound like a chore, but it’s easier than you think—and so worth it for that sparkling, crystal-clear pool! Sand filters are durable, reliable, and simple to care for with just a little know-how. Follow these steps to keep your filter running like a pro, ensuring your pool stays ready for all those cannonballs and lazy floats.

1. Backwash the filter by setting the multiport valve to "Backwash" and running the pump for 2–3 minutes until the water runs clear.
2. Rinse by setting the valve to "Rinse" and running the pump for about 1 minute.
3. Check the sand level inside the filter; replace if it’s over 3–5 years old or has clumped together.
4. Add a sand filter cleaner to remove deep-seated oils and debris if necessary.
5. Return the multiport valve to "Filter" mode before restarting the system.

Cartridge Filter Maintenance Checklist

Cartridge filters are a fantastic choice for keeping your pool water crystal clear with minimal effort! Known for their efficiency and ease of use, these filters require regular attention to ensure they're performing at their best. Proper maintenance not only extends the life of your cartridge, but also keeps your pool sparkling and ready for endless fun. Let's dive into the tips and tricks for maintaining your cartridge filter like a pro!

1. Turn off the pump and release air pressure from the filter tank.
2. Remove the filter cartridge and inspect for damage, wear, or excessive dirt.
3. Clean the cartridge using a garden hose with a spray nozzle, working from top to bottom.
4. Soak the cartridge in a filter cleaning solution if there is excessive buildup of oils or calcium.
5. Rinse thoroughly and let it dry completely before reinstalling.
6. Replace the cartridge if pleats are worn, torn, or if the filter is over 1–2 years old.

D.E. Filter Maintenance Checklist

Maintaining your D.E. filter doesn't just keep your pool sparkling clean—it ensures your system runs like a dream! These filters are known for their superior ability to trap even the tiniest particles, but that means they need a little TLC to stay at peak performance. Here’s a step-by-step guide to keep your D.E. filter in tip-top shape.

1. Backwash the filter by setting the multiport valve to "Backwash" and running the pump until the water runs clear.
2. Open the filter tank and inspect the grids or fingers for damage.
3. Remove and rinse the grids or fingers thoroughly with a garden hose.
4. Soak the grids in a filter cleaning solution if there is stubborn debris.
5. Reassemble the filter and recharge it with the proper amount of D.E. powder (following manufacturer guidelines).
6. Ensure the multiport valve is set to "Filter" before restarting the system.
