How to Use a Multiport Valve on a Pool Filter
A multiport valve is a key feature of your pool’s filtration system, and understanding how to use it correctly can make a huge difference in your pool maintenance. Whether you’re dealing with sand or diatomaceous earth (D.E.) filters, the multiport valve allows you to perform a variety of tasks to keep your pool water clean, clear, and well-maintained. Here’s a guide to help you master your multiport valve and ensure smooth operation.
What Does a Multiport Valve Do?
The multiport valve is located on top or side of your pool filter. Its primary purpose is to control the flow of water through the filter and direct it to different settings. These settings allow you to not only filter water but also clean the filter, backwash it, or even prepare it for winter storage. With just a twist of the valve handle, you can switch between these tasks and keep your filtration system working efficiently.
Important Tip: Never turn the multiport valve while the pool pump is running. Doing so can damage the valve and lead to leaks. Always ensure the pump is off before making adjustments.
Key Multiport Valve Settings
Here are the main settings you’ll find on your pool’s multiport valve and what each one does:
1. Filter
The default setting for your multiport valve is typically the Filter setting. This is the one you’ll use most often. In this position, water is filtered through the media—whether it's sand or diatomaceous earth—removing debris, bacteria, and contaminants to keep your pool water clean and clear.
2. Backwash
Backwashing is a process that cleans the filter by reversing the flow of water, flushing out debris and contaminants. When you notice the pressure gauge rising significantly, it’s time to backwash. Simply turn the valve to the Backwash setting to reverse the water flow and clean the filter. You may also want to use a special filter cleaner for more thorough cleaning.
3. Rinse
After backwashing, always use the Rinse setting to ensure any loosened debris is flushed out before the water is returned to your pool. This step is essential to prevent dirt from flowing back into the pool.
4. Waste
If you need to remove debris from the pool, for example while vacuuming, the Waste setting is your best option. It allows water to bypass the filter and exit the system completely, ensuring debris doesn’t clog the filter. Keep in mind that using this setting will lower your pool's water level, so you’ll need to replace the water afterward.
5. Recirculate
There may be times when you want to circulate the water without filtering it. This could be useful when you’re using chemicals like flocculants to clear up cloudy water. The Recirculate setting moves water through the filter but skips the filtration process, ensuring the chemicals stay in the water while still being circulated.
6. Closed
The Closed setting is used when you need to stop water flow completely. For example, if you’re preparing your pool for seasonal maintenance or maintenance work, this setting will prevent water from entering the filter system. Never run the pump while the valve is in the Closed setting to avoid damaging your equipment.
7. Winter
When preparing your pool for winter, use the Winter or Winterize setting. This setting allows any remaining water inside the valve to expand when freezing, helping to prevent damage to the valve and filter body. It’s usually located between the Waste and Closed settings and can be recognized by the handle not locking into place.
Conclusion
Using a multiport valve on your pool filter might seem a bit daunting at first, but with a little practice, it becomes second nature. Each setting has a specific purpose that contributes to maintaining your pool, whether you're cleaning the filter, adjusting the water flow, or preparing your system for seasonal changes.
By understanding how and when to use each setting, you’ll ensure your AQUASTRONG pool filter keeps your pool water clean and clear all year round. So don’t be intimidated by that valve—embrace it, and enjoy your pristine pool!
