How Do You Backwash a Pool Filter?


Introduction

Maintaining a pool is undoubtedly a time-consuming task. However, it is essential to ensure that the water is clean and safe to use. One of the things that need to be done regularly is backwashing the pool filter. Backwashing your pool filter is critical to keeping your pool sparkling clean, preventing damage to the filter, and maintaining its longevity. This article outlines how to backwash a pool filter correctly.


What is Backwashing?

Backwashing is the process of cleaning your pool filter by reversing the water flow to eliminate the dirt and debris trapped in the filter. Typically, pool filters like sand filters, cartridge filters, and diatomaceous earth (DE) filters, work by trapping dirt and debris in the filter media, which gets clogged over time. When this happens, the water flow is restricted, decreasing the filter's efficiency in cleaning the pool water. Cleaning the filter helps get rid of this clog and ensures the pool's water is clean and safe.


How Often Should You Backwash Your Pool Filter?

The frequency at which you backwash your pool filter depends on various factors, including the pool size, pool usage, and the water's cleanliness. Generally, it is recommended to backwash your pool filter once a week during the pool season. However, if you notice your pool's water is becoming cloudy or there is a decrease in water flow rate, it is likely time to backwash your filter.


How to Backwash a Pool Filter?

Before you start backwashing, turn off the pool pump and ensure that the system is off. Identify the backwash valve or lever, which is typically located on the filter's top or side, to start the process. Here are the steps to follow:


Step 1: Turn off the pump

Ensure the pool pump is turned off before starting the backwashing process. Also, turn off any valves that control water flow to and from the filter.


Step 2: Set the filter to the backwash mode

Turn the valve or lever in the backwash position. For DE filters, you need to engage the backwash mode on the multiport valve.


Step 3: Turn on the pump

Turn on the pump and let it run for 2-3 minutes or until the sight glass (if there is one) runs clear. If you have a DE filter, the pressure gauge will show 10-15 psi.


Step 4: Rinse

Turn the valve or lever to the rinse position and turn on the pump for 30 to 60 seconds. Rinse mode helps to settle down the filter sand or DE powder.


Step 5: Return to Filtration

Once rinsing is done, return the valve or lever to the filtration position and restart the pump. The system will return to normal filtration mode.


Step 6: Dispose of the waste water

The waste water that is backwashed out contains debris, dirt, and pool chemicals, so ensure you discard it in a suitable location.


Conclusion

By following the simple steps outlined above, you can ensure your pool filter is cleaned and maintained correctly. Regular backwashing of your pool filter will help keep the pool water clear, and the filter operating efficiently, prolonging its longevity. Ensure you backwash your pool filter once a week, and if you notice any issues, backwash the pool filter immediately. Maintaining a pool can be a daunting task, but taking the right steps will help you achieve clean, sparkling water.
