Pool maintenance requires regular tasks to be performed to keep the pool clean and running smoothly, such as backwashing the pool filter. But it can be a bit more complicated to understand backwash frequency. Backwashing too infrequently can result in a clogged filter while backwashing too frequently can waste water and energy. In this article, we are going to delve into backwash frequency, its importance, and how robotic pool cleaners can help decrease backwashing frequency.
What Is Backwashing?
Before diving into the correct backwash frequency, let’s briefly cover what backwashing is. Backwashing is a cleaning process for pool filters where water flows through the filter in reverse. This process allows for the removal of debris, dirt, and other contaminants that become trapped in the filter during the filtration process.
Sand filters: Clean the sand medium with backwashing.
DE Filters: Backwashing is used to clean the diatomaceous earth powder.
Cartridge Filters: Generally, they do not require backwashing but do require regular cleaning.
Backwashing is the process of reversing the flow of water through your filter to filter out the accumulated dirt and debris, so you can keep your filter working effectively and the pool water crystal clear. But just how often should you be doing this essential task?
How Often Should You Backwash Your Pool?
There’s no universal answer to how often you should backwash. How often this needs to be done depends on several things, such as what type of filter you have, how much the pool is used, the weather, and how much debris there is in the pool. Let’s break it down:
Filter Type
How often backwashing is needed will depend on which type of pool filter you have.
Sand Filters: Backwash every 4–6 weeks, or when the pressure on the filter rises 8–10 psi over normal.
DE Filter: Backwash every 4-6 weeks or when the pressure rations 10 psi above normal.
Cartridge filters: These filters do not require backwashing, but should be cleaned once every 2–4 months, either by hosing down the cartridge or soaking it in a cleaning solution.
Pool Usage
If your pool is heavily used or frequently hosting pool parties, more debris and contaminants will enter the filter, causing it to clog sooner. Odyssey of Extremely Dirty Pools: If so, you might find yourself backwashing more often — every 3 to 4 weeks instead of the typical 4 to 6.
Weather Conditions
Litter, leaves, and dirt can get washed into your pool in heavy rain, winds, or storms, requiring backwashing more frequently. Likewise, if your pool is in a windy area, or near trees, then you will want to plan to backwash more often because there will be a lot more debris.
Debris Load
If you’re not vacuuming regularly with a robotic pool cleaner or another type of vacuuming system, your pool filter has to work harder to trap debris. The more debris your filter catches, the more often you’ll have to backwash. For pools with heavier debris loads, backwashing every 3-4 weeks may be necessary.
When Should I Backwash My Pool Filter?
Most pool filters also include a pressure gauge to prompt backwashing as needed. As a rule, when the pressure shown on the gauge is 8 to 10 psi higher than the normal operating level, it’s time to backwash.
Other signs most commonly watched for include:
Cloudy Pool Water: Cloudy water in your pool may be the result of a clogged filter. Backwashing can help to restore clarity to the water by clearing debris from the filter.
Juxtaposition of Pressure: An increased pressure reading, particularly when the gauge reads 8-10 psi higher than normal, is a good indication that it’s time for a backwash.
Reduced Water Return: A reduction in the water returned from your return jets can also indicate that your filter is clogged and in need of a backwash.
Can Using A Robotic Pool Cleaner Minimize Backwashing?
Get a Robotic Pool Cleaner if you don’t have one robotic pool cleaner can help you significantly with the need to backwash often. By taking out such large debris before it gets a chance to enter the filter, a robotic cleaner lightens the burden on your filtration system. It means the filter will not clog as soon as the filter and fewer sessions for backwash.
Beatbot AquaSense Pro, for example, is created to clean your pool extra effectively, taking away dirt and preventing it from accumulating on the sides so the filter is working at its finest. Pool cleaning robots like the Beatbot models help keep your swimming pool cleaner, so your filtration system has less load.

How to Backwash Your Pool
Here’s how to backwash a pool filter, step by step:
Turn Off the Pool Pump: Before you do anything, turn off the pool pump.
Set the Filter Valve to Backwash: A “Backwash” setting is used on most multiport valves on the filter.
Step 4: Turn On the Pool Pump: With the valve set to backwash, turn on the pool pump.
Backwash for 2-3 Minutes: Run your system until the discharge from the backwash pipe is clear.
Turn Off the Pool Pump: After backwashing, turn off the pool pump.
Move the Valve to Rinse: This allows the sand or DE powder to settle back down in its place.
Power the Pump Back Up: Start the pump again using the rinse setting for a minute or two, ensuring the filtration media settles properly.
Back to Normal Filter Mode: Return the valve to “Filter,” and return to normal pool operation.
Pool Filter Maintenance — More Tips
Here are some more tips to make sure your pool filter works efficiently so you’re not backwashing as often:
Use a Pool Skimmer: It’s always a good idea to use a pool skimmer to get leaves, dirt, and other things out of the surface of the pool before they sink with a filter that can more easily catch the dirt.
Use a Pool Cleaning Robot: To even make matters easier, the use of a pool cleaning robot or swimming pool robot cleaner will also assist in picking up finer debris and dirt from your pool thus helping your filtration system do less. For robotic cleaning, the Beatbot AquaSense and Beatbot iSkim Ultra are preferred brands.
Conclusion
The frequency of pool filter backwashing varies based on a number of different factors including the type of pool filter in use, the pool frequency of use, and debris loading. Generally, this should be done every 4-6 weeks or when the pressure gauge reads a rise of 8-10 psi. Using a robotic pool cleaner, such as the Beatbot AquaSense Pro, minimizes the debris that gets into the filter, allowing you to stretch the time between backwashing. If your swimming pool isn’t cleaned regularly with a vacuum cleaner for the pool, a skimmer, or even a pool cleaner robot, its water could be letting dirt and debris filter into your pool, potentially damaging your pool filter.
The introduction of Beatbot products ensures a cleaner pool with less effort while also extending the life of your pool filter.
