Pentair cartridge pool filters have become popular among pool owners due to their low maintenance and efficient filtration process. However, like any other pool filter, a Pentair cartridge pool filter needs to be cleaned to ensure proper functioning. This is where backwashing comes in.


Backwashing a Pentair cartridge pool filter involves reversing the flow of water, which flushes out any dirt, algae, or debris that might have been trapped in the filter. In this article, we will guide you on how to backwash your Pentair cartridge pool filter.


Why Do You Need to Backwash Your Pentair Cartridge Pool Filter?


Pentair cartridge pool filters are designed to last for a long time with minimum maintenance. However, over time, dirt and other debris can clog the filter, reducing its efficiency. When this happens, the pool water may become dirty and cloudy, making it unpleasant for swimming.


To avoid this, you need to clean your Pentair cartridge pool filter regularly. Backwashing is an essential step in this process, as it helps to remove all the debris that might have accumulated in the filter.


How to Backwash Your Pentair Cartridge Pool Filter


Backwashing a Pentair cartridge pool filter is a simple process that can be completed in a few minutes. Here's how to do it:


Step 1: Turn off the pool pump


The first step in backwashing your Pentair cartridge pool filter is to turn off the pool pump. This is to ensure that water doesn't flow into the filter while you're cleaning it.


Step 2: Remove the filter cartridge


Once the pool pump is turned off, you can proceed to remove the filter cartridge. To do this, turn the locking ring counter-clockwise and lift it up to remove the filter.


Step 3: Rinse the filter cartridge


After removing the filter cartridge, rinse it thoroughly with a garden hose. Be sure to spray water in between the pleats to remove any dirt trapped in the filter.


Step 4: Reassemble the filter


Once you're done rinsing the filter cartridge, reassemble the filter by placing the cartridge back into the filter housing and securing the locking ring in place.


Step 5: Backwash the filter


To backwash the filter, turn the pool pump on and switch the filter valve to the "Backwash" position. Allow water to flow through the filter for approximately 2 to 3 minutes, or until the water in the sight glass is clear.


Step 6: Rinse the filter


After backwashing, switch the filter valve to the "Rinse" position and allow water to flow through the filter for approximately 1 minute to flush out any remaining debris.


Step 7: Resume normal operations


Once you're done backwashing and rinsing the filter, switch the filter valve back to the "Filter" position and resume normal pool operations.


Tips for Maintaining Your Pentair Cartridge Pool Filter


Aside from backwashing, here are a few tips to help you maintain your Pentair cartridge pool filter:


1. Clean the filter cartridge regularly, preferably once a month or as needed.


2. Check the pressure gauge regularly and backwash the filter when the pressure increases by 8-10 PSI.


3. Consider using a filter cleaner to remove stubborn dirt and debris from the filter.


4. Replace the filter cartridge once a year to ensure maximum efficiency.


5. Always turn off the pool pump before cleaning the filter.
