How to Winterize Sand Pool Filter

As the summer season fades away, it's time to start thinking about the approaching winter. While most people have put their pool covers back on, there is one more task that needs to be done before you can say goodbye to your pool until next year - winterizing the sand pool filter.

Winterizing the sand pool filter is a crucial step in pool maintenance that ensures the filter is protected and ready to use again when you open up the pool next spring. In this article, we will guide you through the process of winterizing a sand pool filter with detailed steps and tips.

Shut off the Power Supply:

Before you begin to winterize your sand pool filter, you need to make sure the power supply to the filter is turned off. If you have a dedicated circuit breaker for the pool filter, turn it off. If not, switch off the main power supply to the pool.

Clean the Filter:

Once you have turned off the power supply, it's time to clean the filter. Begin by backwashing the filter to remove any debris or dirt trapped inside. After backwashing is complete, remove the drain cap at the bottom of the filter and let all the sand drain out. Once the sand has been drained, use a spray attachment on your garden hose to remove any remaining dirt or debris from inside the filter.

Drain and Store the Filter Tank:

Once the filter has been cleaned out, you can proceed to drain the filter tank. Remove the drain cap and let all the water drain out. Next, remove the filter tank from the stand and carefully store it away in a dry place. If you live in a region that experiences freezing temperatures, ensure the filter tank is protected from the frost.

Lubricate O-rings and Gaskets:

To prevent dry rot and to ensure the longevity of the gaskets and o-rings, it's important to lubricate them before storing them away. Use a silicone or Teflon lubricant to coat the gaskets and o-rings.

Cover up the Filter:

To prevent any debris or moisture from getting inside the empty filter tank, it's important to cover up the filter. Use a weather-resistant cover that can withstand the outdoor elements. Carefully wrap the cover around the filter before securing it with zip ties or bungee cords.

In conclusion, winterizing a sand pool filter is a crucial task that should not be skipped. By following these steps, you can ensure that your filter is protected and ready for use when you open up your pool next year.

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
