Gather the Necessary Tools and Materials

Before you start, make sure you have the following items:

• Pool sand or filter sand (not play sand)
• Screwdriver
• Shop vac or a big plastic cup
• Duct tape
• Knife
• Hose

Draining the Filter

Begin by removing the drain plug to let the water drain out of the filter. Allow the water to drain completely.

Removing the Multi-port Valve

Next, take off the collar of the multi-port valve and unscrew the unions to remove the multi-port valve. Be careful not to damage the laterals at the bottom while removing the valve.

Protecting the Stand Pipe

Cover the top of the standpipe with duct tape to prevent sand from entering the pipe and returning to the pool.

Cleaning the Filter

Inspect the laterals to ensure they are not broken. Rinse them down with a hose to clean out any remaining sand. You can leave the laterals in place if they are in good condition.

Preparing the Tank

Replace the drain plug back onto the filter to prevent water from seeping out. Fill the tank halfway with water and ensure the standpipe is centered inside the tank.

Adding New Sand

Using a knife, cut open the bag of pool sand and pour it into the filter. This particular filter requires 350 pounds of sand, so repeat this step seven times.

Securing the Filter

Remove the plug and check the o-ring on the multi-port valve. Ensure it’s in good condition and add a bit of lube if necessary. Pop the o-rings back in from the unions and tighten the clamp.

Backwashing and Rinsing

Attach the backwash hose and turn the multi-port valve to the backwash position. Let it run for approximately two minutes to clean the filter. Then, switch to the rinse position and let it run for one minute.

Final Step

Turn the multi-port valve to the filter position and make sure the pump is primed. Let the filter run and monitor the pressure gauge. Keep the pressure close to the normal level, backwashing when it exceeds the recommended threshold.

Congratulations! You have successfully changed the sand in your sand filter. Your filter is now operating at optimal efficiency, ensuring a clean and enjoyable swimming experience.

Remember to regularly monitor the pressure gauge and perform maintenance as needed. If you have any further questions or need assistance, feel free to reach out to Premier Pool Service. Now, it’s time to sit back, relax, and enjoy your pool. Cheers!
