6 Simple Steps For Backwashing Your Swimming Pool

As the owner of an in-ground swimming pool, you know that there are many different tasks required to keep your pool clean and functional. From maintaining proper water chemistry levels, vacuuming, and simply skimming off the debris, swimming pools require constant upkeep. One way to keep your pools’ filter system in proper working order is through the use of backwashing, or reversing the flow of water through the filter to remove any built-up contaminants.

As dirt accumulates in the swimming pool filter bed, the resistance to water flow increases which causes a reduction in water to the pool. When the flow is insufficient for proper water circulation, or when the pressure gauge indicates a pressure rise of 8-10 lbs. above the clean pressure, it is probably time to clean your pool filter.

Another necessary time to backwash your pool water is after killing an algae bloom or when treating cloudy water. It’s important to remember that you should wait to add chemicals to your pool until after you’ve backwashed, as the process will dispose of some existing water in the pool.

Here are six steps to effectively backwash your pool:

  • Turn off the pump – never change the filter control valves with the pump running.
  • Turn the control valve to the “backwash” position.
  • Turn the pump on and allow it to run until the water is clear as seen in the sight glass at the backwash valve or waste piping. This should take about 2-4 minutes.
  • Shut off the pump and turn the control valve to the ‘rinse’ position.
  • Turn the pump on for 20-30 seconds. This resets the sand bed and sends any residue of dirt into the waste line rather than into your pool.
  • Shut off the pump again and return the valve back to the ‘filter’ position. Turning the pump back on resumes the filter cycle.

Backwashing your in-ground swimming pool is a routine and simple process that’s essential for the health and functionality of your filter. If you follow the above steps, you can be sure that your pool filter is working as efficiently as possible.
