What Is the Operation of a Sand Filter Multiport Valve?


There are plenty of functions of a multiport valve. Here are some of them:

You need to switch the filter after 30 minutes of backwashing. After this, you will find fresh water inside the system and bring it back to its original level.


4. Recirculate


The water from the pump will bypass the filter sand bed without taking much time.


5. Waste


When it comes to the waste feature, the pool water is pumped directly to the multiport valve. It will move the water away from the waste- line and bypass into the sand bed. This position is suitable when the pool has a large buildup of dirt and leaves. You will need to backwash the pool right after vacuuming. Make sure that the waste position is used only for a short period.
