How to Change Pool Filter Sand

When it comes to keeping your pool clean and refreshing, an effective filtration system is a must-have. A pool filter is responsible for filtering out all the dirt, debris, and other contaminants from the water, keeping it free from any impurities. However, as time passes, the filter media such as sand, needs to be changed. In this guide, we will walk you through the process of changing your pool filter sand.

Sub-Title 1: Determine the Correct Type and Amount of Sand for Your Pool Filter

Before starting the process, it's crucial to understand that there is a wide range of pool filter sand available in the market. Hence, you must determine the correct type and quantity of sand that is compatible with your pool filter. It's generally best to refer to the manufacturer's manual for guidance on the right sand size and the quantity suggested. If you cannot find your manual, you can try contacting the manufacturer or a pool professional.

Sub-Title 2: Prepare for the Sand Change

The pool filter should be turned off and the pump should be unplugged from the power source. Ensure that the power supply is disconnected to prevent any mishaps and electrocutions. The valve between the pump and the filter needs to be moved to the 'off' position, and the pressure gauge and sight glass should be detached.

Sub-Title 3: Open the Filter

You will need to disconnect the plumbing lines from your pool equipment before you can open your filter. Once you access the tank, you will need to open it to remove the old sand. There are two main types of filters, and the process of opening them may differ. If you have a top-mounted filter, you will need to remove the multiport valve or sand filter cap, depending on the manufacturer's instructions, to get access to the sand. With a side-mounted filter, the circle-shaped cover situated at the bottom of the filter tank should be opened.

Sub-Title 4: Remove the Old Sand and Run a Rinse Cycle

Using a scooping tool, move the old sand out of the filter and into a trash bag. Be careful while removing the sand to prevent damaging any parts of the filter. After removing the old sand, you should give the filter tank a thorough rinsing to eliminate any remaining sand or debris. To do this, run a rinse cycle for a couple of minutes, and make sure that any residue doesn't clog up your plumbing lines.

Sub-Title 5: Install New Sand and Close the Filter

Once the rinse cycle is complete, it's time to add the new filter sand. Follow the manufacturer's instructions to measure the correct amount of sand required. In most cases, you need to fill the filter tank up to around two-thirds full of new filter sand. Once the sand has been added, it's time to reassemble the filter. Check all the connections and ensure that everything is tightened before turning your pool pump back on.


A clean and well-maintained pool filter is essential for not only ensuring a crystal clear pool but also for preventing any issues with your pool equipment. Changing the filter sand is a job you can do yourself, but it's essential to follow the steps outlined in this guide and take safety precautions while doing so. If you are unsure of any steps or lack the necessary tools, it's best to seek the help of a professional pool cleaning service or pool equipment specialist.
