If you own a pool that is uses a filtration system that is equipped with a multiport, you have several options regarding the operation of your filter. These choices are all located on the multiport. But what do all these options do to the filter and pool and when should I use them?
We’ll explore the 7 positions on a multiport and their usages:
Filtration: Filtration is used most if the time and is the position you will use for standard operation. Filtration pulls water from the pool, filters the water and returns it to the pool as clean water.
Waste: The Waste position on the multiport is used for two reasons. It is used to drop the water level of the pool, or to vacuum debris and water from the pool.
The waste position is very useful because it bypasses the filter, and “wastes” the water.
The most common use of the Waste position is for the cleanup of a very messy pool, usually after a heavy algae bloom.
Winter: The Winter Position will only be used during, you guessed it, winter. When the multiport is set to Winter, it does two things: 1. It pulls the handle assembly off the bottom to prevent the gasket from flattening. 2. Opens all the ports to prevent freezing and cracking within the multiport.
Closed: When the multiport in the closed position, the port that draws water from the pool is closed off. This is important to use when working on your filter. By closing the port that allows water to flow from the pool, you are blocking the water from reaching the filter, which allows you to work on the filter without risk of soaking yourself, or draining your pool. Never run the filter when the multiport is in the closed position. This could lead to irreversible damage to your filtering system.
Backwash: The Backwash position on your filter is used when your filter pressure has reached a high level and the filter needs cleaned. When the multiport is in this position, it reverses the flow of the water within the filter and cleans out the filter. Water will exit from the waste port. Make sure you have a backwash hose connected to the port, and stretched out to an appropriate site for the water waste.
Recirculate: Recirculate is used to circulate chemicals in the water while bypassing the filter. Water runs through the multiport and then moves directly to the pool.
Rinse: The Rinse option on your filter is primarily used after you backwash your filter.
The Rinse option cleans out the multiport only. This option should only be used for approximately 10-15 seconds.
