Sand Filters: Low maintenance but less effective with time

August 4, 2015 Filters, Sand Filters  5

Sand filters are popular because they are low maintenance.

#20 silica pool filter sand is graded to trap particles in the 20 to 100 micron range, which leaves the water cleaner than most other filters. The best thing about sand filters is that the sand gets even more efficient as it traps dirt.

When your pressure gauge shows a reading of 8 to 10 pounds over the start-up pressure, it is time to backwash the captured dirt.

Backwashing is part of your regular service when you choose AMCO.

The actual sand in a properly-sized sand filter that is backwashed as needed typically lasts 7 to 10 years in the Valley’s climate.

If you look at the silica sand used in pool filters under a microscope, the grains have sharp edges. Over time, the motion of water wears these edges away.

In addition, the use of certain biguanide pool chemicals and high amounts of suntan oils can gum-up the sand bed in the filter. Mud balls and channels in the sand are signs your filter is nearing its life expectancy.

But it isn’t just the sand that wears with time. The laterals at the bottom of a sand tank can also get brittle with age, as well as the filter tank itself.

The best practice when refilling sand is to keep to the manufacturer’s specifications. Our technicians bring a wealth of experience to taking care of sand filters and will maintain them to the manufacturer’s standards.
