Pool Maintenance- Cleaning a Cartridge Filter

Swimming pool maintenance is vital to the continued enjoyment of your swimming pool. Naturally when it comes to keeping your pool in fine working condition, a water filter that is clear of dirt and debris is paramount.

You might be wondering, how do I clean my pool’s cartridge filter? It’s actually pretty easy as long as you take a few safety precautions.

Cartridge filters are some of the most popular pool filters in the US today. Though D.E. or a Sand filters are very popular nationwide, we will discuss cleaning those at another time.

To start, make sure the power to the pool pump is switched off. This is a critical safety precaution. Do not work with the pool filter when the power is on. Once the power is off, you will need to open the valve to relieve pressure from the filter. Next, use a socket wrench to remove the “band clamp” that encompasses the filter. Once the clamp is off, you can remove the lid.

Sitting atop the cartridge filters you will find the manifold. Lift it up off of the cartridges and then take the cartridges out of the filter.

Use a garden hose to rinse the cartridges, making sure to get between every pleat. Using a high pressure nozzle will make quick work of any stubborn debris. Clean the inside of the filter of any debris as well as inspecting for any structural issues.

Now is a good time to inspect your filter for signs of wear and tear. Check your O-rings to make sure they are not cracked, damaged, or too flattened. Using silicone gel, lube all o-rings to increase the lifespan of your cartridge filter and mitigate any leaks throughout the rest of your swim season. Take a moment to rinse off the breather tube and inspect the manifold.

Replace the cartridges inside the filter and slide the manifold back on top of the cartridges. Replace the lid and put the clamp back on using a socket wrench.

Turn the power to your equipment back on and close the air release valve as the filter fills with water. Voilà! Your cartridge filter is clean and clear to catch all the dirt and debris you could throw at it. Please note, we make no promises as to the functionality of your filter if you actually throw dirt at it.
