Step-by-Step Guide How to Backwash a Pool Filter
Published November 27, 2024
Keeping your pool water sparkling clean requires regular maintenance, and learning how to backwash a pool is an essential skill for every pool owner. Backwashing flushes dirt, debris, and oils trapped in your filter, restoring its efficiency and ensuring your pool stays inviting. Whether you’re new to pool care or just looking to refine your process, this guide will walk you through every step.

What is Backwashing?
Backwashing reverses water flow through the pool filter, pushing accumulated debris through a waste line. It’s a quick and efficient way to clean filters without manual scrubbing. Pool filters, whether sand, cartridge, or DE (diatomaceous earth), trap impurities as water cycles through. Over time, these impurities clog the filter, increasing pressure and reducing efficiency.
Imagine your filter as a sponge that soaks up everything. Backwashing is a thorough rinse that flushes out all the dirt and grime. For expert help with pool systems, Excel Pools Boca Raton can handle even the trickiest filters.
Why and When Should You Backwash?
Backwashing should be done regularly to maintain water clarity and keep the filtration system working efficiently. Here are some signs it’s time to backwash:
- The pressure gauge reads 8-10 psi higher than normal.
- The pool water looks cloudy or dirty.
- Heavy debris, storms, or increased swimmer activity.
As a rule, backwash sand filters every two weeks, and DE filters around six times yearly. However, consider backwashing more frequently after a busy pool party or during stormy weather to keep the system clear.
Step-by-Step Guide: How to Backwash a Pool Filter
- Turn Off the Pool Pump Always start by switching off the pump. This prevents damage to the filter system and ensures safe operation. Forgetting this step can strain internal components and cause expensive repairs.
- Set the Valve to ‘Backwash’ For multiport systems, turn the handle to the backwash setting and lock it in place. Sand filters typically have six settings, including ‘Filter,’ ‘Backwash,’ and ‘Rinse.’ If you’re unsure about your filter’s mechanism, consult the manufacturer’s manual.
- Run the Pump. Turn the pump back on and let it run for 2-3 minutes. Watch the sight glass (a small window on the filter) for water clarity. Once the water runs clear, the backwashing is complete. This step flushes out all accumulated debris and restores filter performance.
- Turn Off the Pump Again: It is critical to switch off the pump before adjusting the valve. Also, never change the filter’s settings while the pump is running. Doing so could damage internal seals and create leaks.
- Set to ‘Rinse.’ Move the valve to the rinse setting and lock it in place. The rinse cycle repositions the sand or DE inside the filter, ensuring no residual dirt enters the pool when the filter is reset.
- Run the Rinse Cycle. Turn on the pump for about one minute or until the water in the sight glass appears clear. This step resets the filter’s media, preparing it for optimal filtration.
- Return the Valve to ‘Filter.’ After rinsing, set the valve back to the ‘Filter’ position. Ensure the handle locks securely in place to avoid leaks. Restart the pump, and your pool filter is back to peak efficiency.
- Add DE Powder (if applicable). If you have a DE filter, recharge it by adding the appropriate amount of DE powder through the skimmer. Be sure to check your filter manual for the correct amount.
Common Mistakes to Avoid
Many new pool owners make simple mistakes when backwashing their pool filters. Here are some tips to avoid issues:
- Don’t over-backwash. Excessive backwashing wastes water and reduces filter efficiency.
- Always rinse after backwashing. Skipping this step can send dirty water back into the pool.
- Turn off the pump before adjusting the valves. Failing to do this can damage your system.
