How to Backwash a Pool?

Published in Pool Maintenance 3 mins read

Backwashing your pool is a crucial maintenance task that helps keep your water clean and clear. Here’s a step-by-step guide on how to backwash your pool effectively, based on the provided information:

Steps to Backwash Your Pool:

  1. Turn off the pump: Before making any adjustments to your filter system, ensure the pool pump is completely turned off. This prevents any potential damage or accidents.

  2. Set the backwash valve: Locate your backwash valve (it could be a plunger or a multivalve). Turn the valve to the “backwash” setting. This diverts the flow of water, sending it through the filter in reverse to flush out trapped debris.

  3. Backwash the filter: Turn the pump back on and let it run for 2 to 3 minutes, or until the water in the filter's view-glass appears clear. This indicates that the filter is free from debris. The water will initially be murky as the filter releases the trapped dirt. Watch for when it clears up.

  4. Turn off the pump again: Once the water is clear, turn the pool pump off.

  5. Set the valve back: Move the backwash valve back to its normal “filter” setting.

  6. Turn on the pump to clarify: Finally, turn the pump back on and allow the filter to operate under normal conditions until the filter view glass appears clear again, this will remove the dirty water left in the filter pipes.

Why Backwash Your Pool?

  • Removes Debris: Backwashing removes accumulated dirt, algae, and other particles from your pool filter.
  • Maintains Filter Efficiency: By keeping your filter clean, backwashing helps maintain its efficiency, ensuring proper water circulation and filtration.
  • Prolongs Filter Life: Regular backwashing can help extend the lifespan of your pool filter.

Practical Insights:

  • Frequency: The frequency of backwashing depends on how often you use your pool and the amount of debris that accumulates. Monitor your filter's pressure gauge and backwash when the pressure is 8-10 psi higher than normal.
  • Water Conservation: Consider how much water is being used during the backwashing process. Backwash when absolutely needed to avoid overusing water.

By following these steps, you can effectively backwash your pool and keep your water sparkling clean.
