I have an older Hayward pool filter. Is there a link to dowload instructions for replacing or adding sand to the filter?
Here is how I do it. Open the top. Open the drain on the bottom to allow the water out. Remove the plastic water difusser on the top. With a small can, scoop out the sand. When you get to the laterals, remove them for inspection. The sand below the laterals if fine, it does not need to be removed. Put the plug back in. Replace any laterals that may be broken (probably none) Fill the filter with water to about 6 inches above the laterals ... maybe more. The water will protect the laterals from the new sand as you fill the filter. It will also help the sand to pack in around the laterals. Continue filling until you are about 3 inches below the difusser that will go on the top. Make sure you don't bury the little black hose. The purpose of the little black hose is to remove the air from the filter during operation. The hose should ultimately stick up into the inside of the top (cover). I think your filter takes about 300 # of sand. Double check with your professional pool supplier where you purchase your sand. I normally will fill the filter with water before I replace the top. You may want to put on a new "O" ring too ...
This new sand should last you at least 4 to 5 years in non commercial use. After that time, you may want to replace the top 4 inches with new sand.
Thanks for your question @ FixYa.com
