This is January, and I don’t know about you, but we have not really gotten over the feeling of a brand new year. Arizona is still feeling a bit chilly sometimes. But that has only pushed us to keep on our drive with the New Year, New Pool Movement. 

So, in that spirit, let’s talk about your pool filters. There are certain measures you can take to ensure your Pool Filters keep on functioning as new.

New Year, New Pool: Let’s talk about your Pool Filters

Sand Changes and Backwashing your Pool Filters

Pool filters often use sand to help trap dirt and very small particles (between 20-100 microns). Sand filters are some of the lowest maintenance filters on the market.

 

Back-washing

Backwashing your Pool Filters

Most sand filters need to have the sand replaced after around 7-10 years because they will eventually require frequent back-washing or they get calcified or other forms of buildup caused by water balance issues.

Soft Swim or Baquacil (Biguanide chemicals) filters requite annual cleaning to keep it running smoothly. Eventually, the water being pumped over the sand will wear down the sharper edges of the sand, decreasing functionality.

Backwashing

Backwashing your sand-based filter is important. When the pressure gauge reads at 8-10 pounds above the clean, it is time to backwash.

This process is done by turning on the valve so the water runs through the filter backward (removing dirt). This process can be done roughly every 4 weeks.

More often backwashing may indicate a problem (such as the sand needing to be replaced). Make sure to shut off the filter pump before doing anything to the filter. Detailed steps on backwashing can be found here.

There is one very common misconception about sand filters that we need to address. Yes, a “dirty” sand filter can be more efficient than one with fresh sand, but there is always a point where the amount of dirt is hindering the ability.

Brand new sand doesn’t always filter as efficiently, but regular cleaning and replacement is key to a clean pool. Detailed instructions on replacing the sand in a poll filter can be found here.

There are other filter options for pools, but the sand filter option is commonly chosen because the sand is easily, and cheaply replaced and the back-washing process is not very complicated.

Those looking for cheap maintenance often choose this option, though the biggest downside is the frequency at which the sand needs to be back-washed. They are great for pools with high GPM (gallons per minute) capacity and are simple to use and operate.

Some may be concerned with the amount of wastewater created when using and cleaning sand filters, which is understandable—so always check with your local codes before considering using sand filters.
