A Brief Guide to Changing Your Pool’s Sand Filter

The sun is shining and the weather is warming up, which means it’s almost time for pool season! But it’s important that your pool is in top condition before you consider jumping in. Keeping your sand filter well maintained is one of the most important steps when preparing your pool for summer. The sand filter keeps your pool free from dirt and debris. This important component keeps your pool clean through a process known as depth filtration, in which dirt and debris are filtered out in the sand bed as they become trapped between the sand grains.

The sand within the filter needs to be replaced every five to seven years because it will wear out due to regular usage. Over time, the sharp edges on the particles of sand will become worn down and rounded, which hinders their ability to catch the contaminants. This is likely the problem if you’ve recently noticed your pool isn’t as clean as it used to be, or you’re having to backwash your pool more frequently.

Luckily, it’s easy to get your sand filter back to peak performance with help from a pool service in Mandeville, LA. Follow these simple steps to replace the sand in your sand filter:

  • Step 1: First, remove the multiport valve on the top of your filter. Remember to turn off the pool pump first to avoid accidentally being electrocuted.
  • Step 2: Next, release the pressure in the filter tank by turning the drain cap near the bottom of the tank in a counter-clockwise direction. Drain the water out of the tank by removing the cap entirely before disconnecting the waste hose from the multiport valve.
  • Step 3: Remove the unscrew unions connecting the piping to the pump and return ports on the multiport valve. Screw off both bolts on the multiport valve flange clamp, which holds the filter securely on the tank.
  • Step 4: This next step requires a gentle hand. Use a light twisting motion to lift the valve off the pipe in the tank. Try not to pull too quickly or with too much force, as it could break the lateral pipes on the bottom of the tank. Next, place a small piece of tape over the top of the pipe to keep the new sand from entering before removing the old sand from the tank.
  • Step 5: Pour the new sand into the filter until the laterals are completely covered. Leave about six inches of space between the top of the sand and the filter opening.
  • Step 6: Remove the tape from the pipe and reassemble the filter before turning the handle to the backwash position. Turn the pump on and run it for at least two minutes after a steady flow of water emerges from the waste line to flush out any impurities. Lastly, turn the handle back to filter and you’re ready to go!
