How to Winterize Your Pool Pump and Filter

Your pool pump and filter do a lot of heavy lifting, keeping your pool water clean, clear, and safe for swimming. Without them, your pool would quickly turn into a murky mess! The pump circulates water to distribute chemicals evenly and ensure the water stays at the right temperature, while the filter removes debris and helps stop algae and bacteria from taking over.

As fall sets in, it’s time to think about winterizing your pump and filter to protect them from freezing temperatures. Doing this not only prevents damage but also keeps your equipment in top shape for the next swim season. Here’s how you can easily get your pump and filter ready for winter.

Protect Your Pump and Filter from Freezing

We all know that when water freezes, it expands, and that expansion can be destructive. It can split pipes, crack pumps, and cause expensive damage to your equipment. Even if you live in a warmer climate, freezing temperatures can still sneak up and wreak havoc. The goal here is to make sure no water is left inside your pump and filter that could freeze and cause damage.

Steps to Winterize Your Pool Pump and Filter

Step 1: Turn Off Your Pool Heater

If you have a pool heater, you’ll want to shut it off first. Give the water some time to cool down—about 15 to 20 minutes. If you skip this step, water left in the heater can get too hot, potentially damaging the pipes.

Step 2: Power Down the Pump

Turn off the power to your pump before doing anything else. Safety first!

Step 3: Disconnect the Pump and Filter

After you’ve powered everything down, disconnect both the pump and filter from the pool’s system. This makes draining and cleaning easier.

Step 4: Drain the Pump

Make sure all the water has drained from the pump. For extra peace of mind, you can flip the pump upside down to shake out any lingering water.

Step 5: Drain the Filter

Next, remove the drain cap from the bottom of your filter and let the water drain completely. It’s a good idea to let it drain overnight. Don’t forget to store the cap in a safe place for next season!

Step 6: Remove Pump Drain Plugs

Take out the drain plugs from your pump and store them somewhere you won’t forget. You won’t need these again until next spring.

Step 7: Quick Pump Run

Turn the pump on for just a second or two—literally. This helps push out any remaining water, but don’t let it run too long, or you risk damaging the pump.

Step 8: Blow Out the Pipes

Finally, use a shop vacuum or air compressor to blow out any remaining water from the pipes. Loosen any quick-connect fittings to ensure the water flows out completely.

Why Winterizing Matters

By properly winterizing your pool pump and filter, you’re extending the lifespan of your equipment. It’ll run more efficiently, which means fewer repairs, lower energy bills, and more savings in the long run. Plus, since the pump and filter prevent algae and bacteria growth, your family’s health is on the line. So, take a little time this fall to winterize your pool—it’ll save you a lot of hassle when swimming season rolls around again.
