Back wash Filter. Back-washing your swimming pool's sand filter is an important part of pool maintenance and should be done "regularly".
Why does a sand filter need to be back-washed? Sand filters need to be back-washed because you need to routinely get rid of the accumulations of dirt and debris that collect on and in the sand bed. As the sand inside the filter gets dirty, the flow of water through the filter gradually slows down until its unable to trap any further dirt or debris.
When the pressure gauge measures approximately 10 psi HIGHER than initial start OR when you notice that the flow of water returning to the pool has dramatically slowed down, it is time to backwash the filter.
I'll provide a couple of extra hints at the end of this section.
Whether your sand filter has a top mounted valve as shown in the picture or a side mounted valve, the operation is the same.
Note 1: It is very necessary to TURN OFF THE PUMP when changing valve positions. If you don't turn the pump off, you could and will damage the valve causing it to leak.
Note 2: Back-washing should only be done AS NECESSARY, typically no more than once every 7 to 10 days during the season. The "dirtier" a filter is allowed to become, the finer a particle it will be able to remove from the water. Even at spring pool opening, allow the filter to filter as long as possible before back-washing.
Note 3: Periodically CHEMICALLY CLEAN the sand. Sand media typically can last 5 to 7 YEARS when it is chemically cleaned twice per season. Not chemically cleaning the filter sand cuts the life of the sand to 2 to 3 years.
It is incredibly important to CHEMICALLY CLEAN your swimming pool filter. Regardless of whether it is a Sand, Cartridge or DE (Diatomaceous Earth) filter, the media MUST be periodically chemically cleaned, then back wash filter. This is good pool maintenance.
Chemical cleaning your filter would be equivalent to properly washing your dishes or clothing. Rinsing alone does nothing to clean dishes, pots & pans or dirt clothes. Detergents and the scrubbing action of the dishwasher, washing machine or hand wash, scrubs off the excess debris plus the detergents breakdown the accumulated greases and oils that foul the filter, shortening its life.
Sand grains actually wear down (loose their sharp edges which trap dirt) & accumulate grease. The Cartridge fiber gets dirty like a pair of jeans or shirt. The DE septum which holds the DE, gets dirty like the Cartridge fabric. Here's how to take care of each of these filters...
Cartridge & DE Filters:
IMPORTANT NOTE: Be sure to DE-GREASE the filter FIRST. Using acid to clean filters first before de-greasing will set the accumulated greases and oils into the filter media.
