How to Dispose of Sand from Pool Filter: The Essential Guide

Do you have a swimming pool at your home? If so, you know that keeping it clean requires a lot of work. One of the tasks that you will need to do regularly is changing the sand in the pool filter. This can be a messy job, but it is important to do if you want to keep your pool looking and functioning at its best. This blog post will teach you how to dispose of sand from pool filter properly.

How to Dispose of Sand from Pool Filter

Some pool owners indefinitely leave the sand in their filtering system and rely on backwashing to keep it clean, but they are the exception. To obtain the maximum performance from your filter, manufacturers and pool maintenance professionals recommend changing it every five years. Some filters can contain as much as 300 pounds of sand, which is excessive to carry away off-site.

Because the filter needs to be changed so seldom, it’s simple to find uses for the old sand around the home. Please don’t put it in sandboxes or other play areas where children or pets can indulge.

How is Pool Filter Sand Different from Normal Sand?

Pool filter sand differs from ordinary sand in several respects. Pool sand is also a finer product. Pool filter sand is generally made of silica quartz, classified as a carcinogen because it can induce severe respiratory problems if inhaled. Fine silica quartz inhalation can lead to silicosis, an illness that can be fatal if left untreated.

However, standard sandbox sand comprises a variety of minerals and is not harmful in any way. Children and animals should not be allowed to play with pool silica sand or place it in areas where they can reach it. As a result, old pool filter sand must be disposed of properly.

Why You Should Not Reuse Pool Filter Sand?

If you have ever had to change the sand in your pool filter, you know how dirty and grimy it can be. This is because the sand filters out all the dirt and debris from the water as it circulates through the system. Over time, the sand becomes clogged with these contaminants and can no longer do its job effectively.

Additionally, when you remove old pool filter sand, it is important to dispose of it properly. You should not simply reuse it or put it back in the pool. Doing so could introduce harmful bacteria and other contaminants into the water.

When Should You Change Pool Filter Sand?

As we mentioned above, you should typically change the sand in your pool filter every five years. However, there are a few circumstances where you may need to do it more frequently. If you notice that your filter is not working as well as it used to, it is probably time for a change. You may also need to replace the sand more often if you have a lot of trees or other debris around your pool that can clog up the system.

If you are not sure how often to change the sand in your pool filter, you should consult with a professional. They will be able to give you specific advice based on the type of pool and filtration system you have.

Pool Sand Is Not Play Sand

The disadvantage of employing pool sand in playgrounds is the potential for contaminants to accumulate on the sand. They’re the same elements you come into contact with when you get into the water, but pool sand has a higher concentration. They might be harmful to one’s health.

Another issue is the sand’s composition. Unlike beach and play sands, Pool sand largely comprises crushed silica quartz rather than a variety of minerals. The dust from this sort of sand is a Class 1A carcinogen that can lead to silicosis if inhaled over time. It isn’t safe for humans or animals, and it’s not an excellent filler for cat litter boxes in terms of safety or purity.

What Is Backwashing a Pool Filter?

Whether you’ve heard the phrase “c” or “backwash a pool,” both mean reversing the circulation of water in your filter to remove impurities. Pool water goes through your D.E. filter or sand filter, leaving behind dirt, oils, and other particles caught in the media—either D.E. powder or sand—when it passes through it.

As time progresses, the filter medium will get clogged as water only moves in one direction, reducing your filter’s effectiveness. You backwash a pool by sending water backward through the filter and out the waste or drain port. All debris trapped in the filter is forced to dislodge during this process, so you can remove it and return your filtration system to normal function.

How to Dispose of Sand from Pool Filter?

This is not a uniform process, and it’s specific to each filter. There isn’t much of a difference here, but you want to be sure to follow your filter’s instructions instead of relying on general advice to change everything correctly.

Fortunately, this may be as easy as consulting your owner’s handbook and doing a basic check-in. If you’re concerned, you may always contact your pool service for assistance or even have them come out and take care of it!

After you’ve gotten all of the sand from your pool filter, you’ll have to find a place for it. It’s packed with filth, so there’s no way you could use it as a sandbox or let it pile up in a mound in the yard. There are a few different techniques to get rid of this stuff without calling in the heavy artillery!

1. Use Pool Sand for Landscaping

Pool sand granules are usually less than a millimeter in diameter and maybe even smaller. This fine combination is fantastic as an underlayment for paving stones and a filler between the rocks. It can also fill holes in the lawn or garden, spread on the surface of existing dirt pathways, or apply to existing dirt paths to fill cracks. None of these uses exposes you to silica dust or pool hazards.

2. Save Pool Sand for the Winter

The average pool filter includes the same amount of sand as approximately seven bags, which is enough to keep your walkways and stairs slip-free for one or two seasons. The sand should be stored in covered 5-gallon buckets. Each bucket holds about the same amount as one bag.

3. Bury It

Because of the pollutants, it contains, Pool sand should never be left in a pile in the yard. If you can’t think of any other use for it around the house and don’t want to transport it to a landfill, dig a hole in your yard or garden and bury it.

If you opt for this option, put it as far away from drainage pipes as possible since flowing water will carry it into the ground, leaving a space that you’ll need to refill with dirt.

4. Hire a Disposal Expert

Pool filter sand is classified as a hazardous substance, so you should not dispose of it in your ordinary trash can. To properly get rid of the sand, contact a specialist or take it to a disposal facility.

Bottom Line

The sand in your pool’s filtration system is not the same as the sand you played with at the beach or in a sandbox. It is considerably finer, which makes it hazardous to breathe if ingested. It’s critical to understand how to properly dispose of it to protect yourself and those in your home.

After you’ve disposed of it and replaced it with new sand, you and your family can once again enjoy clean and safe water.


How much does it cost to replace pool filter sand?

The cost of replacing pool filter sand varies depending on the type and size of your pool. Generally, it costs between $100 and $200 to replace the sand in a typical 20,000-gallon inground pool. For above-ground pools, the cost is usually between $50 and $100.

Can I use beach sand in my pool filter?

No, it would help if you did not use beach sand in your pool filter. Beach sand is coarser than pool filter sand and contains salt, damaging your filtration system. In addition, beach sand can introduce bacteria and other contaminants into your pool.

What is the best way to dispose of pool filter sand?

The best way to dispose of pool filter sand is to use it for landscaping, save it for the winter, bury it, or hire a disposal expert. Pool filter sand should never be disposed of in your ordinary trash can because it is classified as a hazardous substance.
