Pool filter valves are an essential part of the pool's filtration system, allowing you to control the flow of water through the filter for various functions such as filtration, backwashing, rinsing etc. The most common type of valve used in pool filtration systems is the multiport valve, which can have multiple settings. Knowing these settings is crucial for proper pool maintenance and operation.
Here are the typical settings found on a multiport valve and their functions:
1. Filter
Purpose: This is the standard setting for normal pool operation. Water flows from the pool through the filter media (sand, DE, or cartridge) and then returns to the pool.
When to Use: Use this setting for everyday filtration of pool water.
2. Backwash
Purpose: The backwash setting reverses the flow of water through the filter media, flushing out trapped dirt and debris to clean the filter.
When to Use: Use this setting when the pressure gauge indicates a rise in pressure (usually 8-10 psi above normal), signifying the filter needs cleaning.
3. Rinse
Purpose: The rinse setting helps clear any remaining debris from the filter and plumbing after backwashing, preventing it from returning to the pool.
When to Use: Use this setting immediately after backwashing, typically for 30 seconds to 1 minute, to settle the filter media and prevent cloudy water from entering the pool.
4. Waste
Purpose: In the waste setting, water is diverted directly out of the pool system, bypassing the filter. This setting is used to lower the water level or to vacuum up large amounts of debris directly to waste.
When to Use: Use this setting for vacuuming large debris or draining the pool, such as after a heavy rain or when cleaning up after algae treatment.
5. Recirculate
Purpose: The recirculate setting bypasses the filter and sends water directly back to the pool. This is useful for circulating water without filtering it.
When to Use: Use this setting when you want to circulate chemicals evenly throughout the pool without filtering, such as during certain chemical treatments.
6. Closed
Purpose: The closed setting stops all water flow through the valve and filter system.
When to Use: This setting is typically used when servicing the pump or filter system. However, it should not be used when the pump is running, as it can cause damage.
7. Winterize
Purpose: The winterize setting is used to prepare the system for winter by preventing water flow and protecting the valve and filter from freezing.
When to Use: Use this setting when closing the pool for the winter season, after properly draining the system.
Fenlin Important Considerations
1. Turn Off the Pump: Always turn off the pool pump before changing the valve setting to prevent damage to the system and ensure safety.
2. Pressure Gauge Monitoring: Regularly check the pressure gauge to determine when backwashing or rinsing is needed. An increase in pressure usually indicates that the filter needs cleaning.
3. Regular Maintenance: Regularly clean and maintain your filter and multiport valve to ensure efficient operation and extend the lifespan of your pool equipment.
4. Consult Manufacturer’s Manual: Different pool filter systems may have specific instructions or additional settings. Always refer to the manufacturer's manual for precise guidance on operating and maintaining your specific equipment.
Understanding and correctly using the various settings on your pool filter valve will help maintain clean and healthy pool water, ensure efficient operation of your filtration system, and prolong the life of your pool equipment.
