While specific instructions can vary slightly based on the exact Summer Waves sand filter model, the general process involves using the multi-port valve to reverse the water flow and flush out accumulated debris.
Here's how to backwash a Summer Waves sand filter, based on general principles and the provided reference:
- Turn the pump off. Always turn off the pump before changing the multi-port valve position. This prevents damage to the pump and filter.
- Set the multi-port valve to the "Backwash" position. The multi-port valve is typically located on top of or on the side of the filter. Rotate the handle to select the "Backwash" setting.
- Turn the pump back on. Allow the pump to run.
- Monitor the sight glass. Locate the sight glass on the multi-port valve. Initially, the water flowing through the sight glass will be cloudy as the filter begins to flush out the dirt and debris.
- Continue backwashing until the water in the sight glass is clear. This indicates that the filter is clean. The time required will vary depending on how dirty the filter is, but it usually takes a few minutes.
- Turn the pump off again.
- Set the multi-port valve to the "Rinse" position. This helps to settle the sand bed after backwashing and prevents any remaining debris from entering the pool.
- Turn the pump back on. Run the pump in the "Rinse" position for about 30 seconds to 1 minute.
- Turn the pump off again.
- Set the multi-port valve back to the "Filter" position. This is the normal operating position for filtering your pool water.
- Turn the pump back on. Your sand filter is now backwashed and ready to use.
Important Considerations:
- Frequency: Backwash your sand filter when the pressure gauge reads 8-10 PSI above the normal operating pressure, or about once a week, depending on usage and debris levels.
- Water Level: Backwashing will lower the water level in your pool, so be prepared to add water after backwashing.
- Manufacturer's Instructions: Always refer to your Summer Waves sand filter's specific owner's manual for detailed instructions and safety precautions. The above steps are a general guide.
- Waste Water Disposal: Be mindful of where the waste water from the backwash is being discharged. Avoid draining it into areas that could cause erosion or damage to the environment.
