How to Vacuum to Waste with a Bestway Sand Filter: A Comprehensive Guide

To vacuum to waste with a Bestway sand filter, you’ll need to bypass the filter and direct the vacuumed debris directly out of the pool. This is typically done by adjusting the multi-port valve on your filter to the “Waste” or “Drain” setting before connecting your vacuum and commencing cleaning, preventing clogging of the sand filter.

Understanding the Need for Vacuuming to Waste

Vacuuming your pool is a crucial part of maintaining a clean and healthy swimming environment. However, sometimes, the amount of debris is simply too much for your filter to handle effectively. This is where vacuuming to waste becomes essential. Large amounts of algae, leaves, or dead insects can quickly clog your sand filter, reducing its efficiency and potentially damaging the system. By vacuuming to waste, you bypass the filter altogether, sending the dirty water directly out of the pool and preventing the filter from becoming overwhelmed. This method is particularly useful after shocking the pool, during heavy algae blooms, or when dealing with a significant accumulation of sediment.

Step-by-Step Guide to Vacuuming to Waste with a Bestway Sand Filter

Before you begin, it’s crucial to understand the specific model of your Bestway sand filter, as valve configurations may vary slightly. Always consult your owner’s manual for detailed instructions specific to your model. However, the general process is as follows:

1. Turn Off the Pump: This is a critical safety precaution. Ensure the pump is completely off before manipulating any valves.

2. Connect Your Vacuum Hose: Attach your vacuum hose to the vacuum head. Lower the vacuum head into the pool, allowing the hose to fill with water to eliminate air pockets.

3. Connect the Vacuum Hose to the Skimmer: Plug the other end of the vacuum hose into the skimmer. You may need to remove the skimmer basket first.

4. Locate the Multi-Port Valve: This valve is typically located on the side of your sand filter.

5. Set the Valve to “Waste” or “Drain”: This is the crucial step. Carefully turn the multi-port valve to the “Waste” or “Drain” setting. Ensure you’re doing this with the pump OFF to prevent damage to the valve and seals. The marking may vary depending on the specific model.

6. Prepare for Water Loss: Vacuuming to waste removes water from your pool. Have a garden hose ready to add fresh water simultaneously to prevent the water level from dropping too low, which could damage your pump if it runs dry. Pay close attention to the water level throughout the process.

7. Turn On the Pump: Carefully turn the pump back on.

8. Begin Vacuuming: Start vacuuming the pool floor systematically, overlapping each pass to ensure thorough cleaning. Move slowly and steadily to avoid stirring up debris.

9. Monitor Water Level: Continue adding fresh water as needed to maintain a safe water level in the pool.

10. Turn Off the Pump (Again!): Once you’ve finished vacuuming or the pool is clean enough, immediately turn off the pump.

11. Set the Valve Back to “Filter”: Return the multi-port valve to the “Filter” setting.

12. Backwash (Optional but Recommended): After vacuuming to waste, it’s generally a good idea to backwash your sand filter to remove any residual debris that may have bypassed the system. Follow your manufacturer’s instructions for backwashing.

13. Rinse (Optional but Recommended): After backwashing, run the filter on the “Rinse” setting for a short period to settle the sand bed.

14. Turn the Pump Back On: Return to normal filtration operation by turning the pump back on in the “Filter” position.

Important Considerations and Best Practices

• Pool Size and Water Replacement: Be mindful of how much water you’re removing from the pool. Larger pools can handle more waste without significant water level drops. Smaller pools require more careful monitoring and frequent water additions.
• Discharge Location: Ensure the water being discharged is directed away from your pool and foundation to avoid erosion or other damage.
• Sand Filter Maintenance: Regular backwashing and sand replacement (every 3-5 years) are crucial for maintaining the efficiency of your sand filter.
• Water Chemistry: Regularly test and adjust your pool’s water chemistry to ensure optimal sanitation and prevent algae growth.
• Observe the Vacuumed Water: Monitoring the water being discharged can provide insights into the type and amount of debris being removed. If the water suddenly turns clear, it may indicate that you’ve removed most of the debris and can switch back to normal filtration.

Frequently Asked Questions (FAQs)

H3 FAQ 1: Why is it important to turn the pump off before changing the multi-port valve position?

Turning off the pump prevents pressure buildup and potential damage to the multi-port valve. Changing the valve position under pressure can damage the seals and internal components, leading to leaks and reduced filter performance.

H3 FAQ 2: What happens if I forget to add water while vacuuming to waste?

If you forget to add water, the water level can drop too low, potentially exposing the pump. Running a pump dry can cause it to overheat and burn out, resulting in costly repairs or replacement.

H3 FAQ 3: How do I know if my sand filter is clogged?

Signs of a clogged sand filter include reduced water flow, increased pressure on the filter gauge, and cloudy water. If you notice these symptoms, backwash your filter immediately or consider vacuuming to waste if the debris is excessive.

H3 FAQ 4: Can I vacuum to waste even if my pool water is clear?

While primarily used for heavy debris, vacuuming to waste can still be beneficial even with clear water, especially after shocking the pool or using flocculant. This helps remove dead algae and settled particles that might otherwise cloud the water.

H3 FAQ 5: How often should I vacuum to waste?

The frequency depends on the condition of your pool. If you regularly have excessive debris, vacuuming to waste might be necessary more frequently. However, if your pool is generally clean, regular filtration and occasional vacuuming on the “Filter” setting may suffice.

H3 FAQ 6: My Bestway sand filter doesn’t have a “Waste” or “Drain” setting. What should I do?

Consult your owner’s manual for alternative options. Some models may have a similar setting with a different name or a different method for bypassing the filter. If you can’t find a suitable setting, contact Bestway customer support for assistance.

H3 FAQ 7: What is the best time of day to vacuum to waste?

The best time is when the pool is not in use and the sun isn’t directly overhead. This allows you to see the debris more easily and avoid disrupting swimmers.

H3 FAQ 8: Is vacuuming to waste bad for the environment because it wastes water?

While it does waste water, it’s sometimes a necessary evil to maintain a clean and healthy pool. Minimize water loss by adding water simultaneously and addressing the root cause of excessive debris to reduce the need for frequent vacuuming to waste. Consider using a pool cover to prevent leaves and debris from entering the pool in the first place.

H3 FAQ 9: How do I prime the pump after vacuuming to waste if air gets into the system?

Priming the pump involves removing air from the pump and impeller. Consult your pump’s manual for the specific priming procedure, which usually involves opening an air relief valve and allowing water to fill the pump housing.

H3 FAQ 10: Can I use a robotic pool cleaner instead of vacuuming to waste?

Robotic pool cleaners can be effective for general cleaning, but they may not be suitable for removing large amounts of debris. Vacuuming to waste is still the preferred method for heavily soiled pools.

H3 FAQ 11: How long should I run the pump after vacuuming to waste?

After returning the multi-port valve to the “Filter” setting, run the pump for at least 8 hours, or preferably 24 hours, to allow the filter to thoroughly clean the remaining water.

H3 FAQ 12: Can I vacuum to waste while the pool is being filled?

While not ideal, it’s possible to vacuum to waste while filling the pool. This helps remove any sediment or debris introduced during the filling process. However, monitor the water level carefully and ensure the pump doesn’t run dry.

By following these steps and understanding the nuances of vacuuming to waste with your Bestway sand filter, you can maintain a clean, healthy, and enjoyable swimming pool all season long. Always prioritize safety and consult your owner’s manual for specific instructions related to your equipment.
