How to Change Sand in Pool Filter

Pool filters are an essential part of pool maintenance, helping to keep the water clean and safe in your swimming pool. But just like with any piece of equipment, over time the sand used to filter the water can wear out and become less effective.

When your pool’s sand becomes old and clumped together, it can cause cloudy or dirty water. That’s when it’s time to replace the sand in your filter.

Altering your pool sand isn’t a particularly complex process, and even experienced homeowners can do it. But it’s essential to know the steps you should take prior to beginning this task so that it is done safely and correctly.

First, shut off your pool pump and disconnect power at the circuit breaker panel to prevent any electrical interference while working on the filter. Secondly, open the air relief valve on your pool filter to release pressure in the system.

Once all air has been expelled, drain the water from your filter. Doing so will help clear away any remaining sand or extra weight in the system.

You can use a shop vac to remove the sand from your pool filter tank, but you might want to consider renting one from your local hardware or home improvement store. This will make the job much simpler. However, if you do not have access to one, there are other methods available for taking out sand from the tank.

Before you begin, be sure to gather all necessary tools and supplies. Doing this will make the entire process go much smoother and faster.

Once all your components are ready to go, drain the water from your pool filter and make preparations for a fresh batch of sand. Doing this gives you an estimate for how much replacement sand your filter requires so you can purchase it accordingly.

If you’re uncertain how much sand your filter requires, consult the manual that came with your pool filter or visit your manufacturer’s website for instructions.

While you wait for your sand to arrive, inspect your multiport valve for signs of damage. If the o-ring is worn out, this could cause your valve to leak. Additionally, look at the laterals of your filter for any cracks or deterioration.

According to the type of sand your filter uses, it should be replaced every five to six years. However, if you do not regularly use your pool, the sand may last longer; so consult with a local pool service provider about when to change out your sand.

Once your sand is replaced, you can enjoy your sparkling pool again! Just remember to always backwash and rinse your filter after replacing your sand.

This will prevent your sand from getting stuck in the filter and clogging laterals, giving your pool less efficient filtration. Once complete, simply reinstall the lid or valve on your sand filter and restart its cycle; you’ll notice an immediate improvement!
