Are you looking for an efficient and straightforward way to keep your pool water looking sparkling clean? A great option is to backwash the pool’s sand filter. Regular backwashing prevents build-up of dirt, debris, and filters out salt and chemicals. By backwashing your sand filter regularly, you will ensure a higher quality of water and help maintain the longevity of your filter and pool. In this article, we will break down why and how you should backwash a sand filter, as well as answer some common questions that you may have.
Why Backwash?
Backwashing a sand filter is an essential part of pool maintenance. It rids the filter of any dirt, debris, and buildup. It also removes some of the salt and chemicals in the water, allowing for a higher quality of water. Regular backwashing also helps prevent your filter from failing, increasing its lifespan.
How to Backwash a Sand Filter
Before Backwashing
Before backwashing a sand filter, it’s important to assess the filter for any potential problems. Look for obvious cracks or rips in any of the hoses connecting your filter and pump. Check the filter for any signs of wear and tear. Make sure the tank is secure and not loose from the base. Once everything is checked, your filter is ready to be backwashed.
Backwashing the Sand Filter
Before starting, make sure the pump is turned off. If the filter has a multiport valve, turn it to the “Backwash” setting. This opens up a distinct outlet, allowing the sand particles to exit the filter. Turn the pump back on and allow it to run for 3–5 minutes. When done, turn the pump off and move the valve to the “Rinse” setting. This will clear away any remaining dirt or debris in the filter. Let the pump run for another 30 seconds to 1 minute and then turn the pump off. Move the valve back to the “Filter” setting so the filter can run again.
Cleaning the Debris in the Pool
Do a quick check to make sure all the hoses are secure and tight. Turn the pump on and let it clean the pool for 15–20 minutes. You may need to do some manual cleaning if the pool has major debris buildup. However, for regular maintenance cleaning, the pump should work well.
Tank Maintenance
Sand filters need regular maintenance to prevent the build-up of dirt and debris. Empty the tank of all filter media like sand and gravel and rinse out the tank. Then add the clean filter media back into the tank. Make sure to check the filter pressure and adjust according to the manufacturer’s instructions.
Additional Tips
- Keep an eye on the filter pressure, as a rising pressure may be indicative of a clogged filter.
- Check the backwash hose for any blockages. If needed, run a cleaning device through it to unclog it.
- Maintain water levels in your pool to prevent any pool filter issues.
People Also Ask

What settings should I use when backwashing my sand filter?

Yes, over backwashing is not a huge concern. If you are noticing a lot of dirt and debris build-up, it is probably more beneficial to backwash more often. Too little backwashing can be worse since it can cause clogs.
Is a sand filter better than a cartridge filter?
