Understanding Your Pool Filter


Before you start changing your pool filter, it’s important to understand the different types of filters that are available. There are three types of filters: Sand, Cartridge, and Diatomaceous Earth (DE).


Sand filters use sand to filter out dirt and debris from the pool water. Cartridge filters use pleated polyester fabric to capture dirt and debris. DE filters use a powder called DE, which is made from finely ground fossils, to remove dirt and debris from the water.


Signs it’s Time to Change Your Pool Filter


It’s important to keep an eye out for signs that your pool filter needs to be changed. Some signs to watch out for include:


- The water is not as clear as it used to be

- There is debris in the pool despite regular cleaning

- The pool isn’t filtering water properly

- The pressure gauge is showing a high PSI (pounds per square inch)

- It’s been over a year since the filter has been changed


If you notice any of these signs, it’s time to change your pool filter.


How to Remove Your Old Pool Filter


The first step to changing your pool filter is to turn off the pool pump. This will prevent any water from flowing into the filter, making it easier to remove.


Next, you’ll need to remove the old filter. The method for doing this will depend on the type of filter you have. Sand filters typically have a multiport valve on top that needs to be removed. Cartridge filters will have a lid that needs to be unscrewed. DE filters can be a bit more complicated and may require professional help to remove.


Once the old filter is removed, you can dispose of it properly.


Installing Your New Pool Filter


Now that the old filter is out of the way, it’s time to install the new one. The method for doing this will, again, depend on the type of filter you have.


For sand filters, you’ll need to add the correct amount of sand to the filter. Make sure to follow the manufacturer’s instructions for how much sand to add.


For cartridge filters, you’ll simply need to place the new cartridge in the filter housing and screw the lid back on.


For DE filters, you’ll need to add the correct amount of DE powder to the filter. Again, make sure to follow the manufacturer’s instructions for how much DE to add.


Tips for Maintaining Your Pool Filter


Once you’ve changed your pool filter, it’s important to maintain it properly. Here are some tips to help you do this:


- Clean the filter regularly

- Keep an eye on the pressure gauge and backwash or clean the filter when the PSI gets too high

- Check the filter o-rings for wear and tear and replace them if needed

- Use only the recommended type and amount of filter media (sand, cartridges or DE)

- Hire a professional if you’re unsure about changing the filter yourself


Conclusion


Changing a pool filter is an essential part of maintaining your pool. With the right knowledge and tools, you can do it yourself and keep your pool clean and clear all season long. Remember to keep an eye out for signs that it’s time to change your filter and don’t hesitate to ask for help if you need it.
