Here's how to effectively backwash and vacuum your pool, combining both processes into one efficient maintenance routine.

Backwashing and Vacuuming Your Pool: Step-by-Step Guide

Backwashing is essential for cleaning your pool's filter, while vacuuming removes debris from the pool floor. Combining them ensures your pool remains clean and healthy. According to our source, backwashing is done before vacuuming.

Step-by-Step Process:

  1. Prepare for Backwash:

    • Turn off your pool pump.
    • Locate your pool's multiport valve, usually found near the filter system.
    • Turn the multiport valve to the "Backwash" setting.
  2. Backwash the Filter:

    • Turn the pool pump back on.
    • The water flow will reverse, cleaning the filter by flushing out accumulated debris.
      • Run the backwash for approximately two to three minutes or until the water in the sight glass turns clear.
    • Turn off the pool pump after the backwash cycle.
  3. Prepare for Vacuuming:

    • Turn the multiport valve to the "Filter" or "Rinse" setting. Some pool systems recommend a "Rinse" setting for a short time after backwashing to settle the sand. If you have a different filter type you may need to consult the manual, but the general concept is the same.
    • Turn the pool pump back on.
    • Connect your vacuum hose to the vacuum head and the skimmer.
    • Fill the vacuum hose with water by placing it in front of a return jet until all the air is purged from the hose. This prevents air from entering the pump, helping it prime efficiently.
  4. Vacuum the Pool:

    • Slowly move the vacuum head across the pool floor, removing any debris.
    • Do not rush this process, as you could stir up the debris into the water.
    • Overlap each pass of the vacuum to ensure you do not miss any spots.
  5. Clean and Store Equipment:

    • Turn off the pump once done vacuuming.
    • Disconnect the vacuum hose from the skimmer and the vacuum head.
    • Empty the skimmer basket.
    • Store your equipment in a safe location.
