How a Pool Sand Filter Works

A pool sand filter works in much the as a cartridge filter but at a lower rate of turnover. It is designed to last 7 to 10 years with proper maintenance, and is a great option for those looking for an inexpensive pool solution.

In operation, a pool pump sends dirty water into the filter tank where it is picked up by gravity through the head and distributed over the sand. The sand works to trap particulates in the gaps and fines between the grains of sand. Clean water then flows out the bottom laterals and back into your pool.

When the sand needs to be replaced, it can be done by opening the top of the tank and manually scooping or vacuuming out old sand through a narrow opening. Then it is important to reload new sand into the tank with a precise amount. This is best achieved by following the specific sand replacement guidelines of your particular filter.

A sand filter for pool uses a special type of sand to trap dirt and debris that floats in your water. Sand meant for this filtration system is made to be the right size so it will easily fit through your filter pump while catching unwanted particles that make their way into your pool. A sand filter will also last for years and doesn't require as much maintenance as a cartridge filter. This is a great option for pools that are surrounded by trees and plants as it will quickly capture fallen leaves, petals, and pollen. It is important to regularly backwash the sand filter to keep it functioning well.

If you don't backwash your sand filter enough, it will build up too much and lose its ability to clean the pool. This happens because the rough edges on the sand, which are how it is able to catch contaminants, slowly wear down and smooth out over time. As this occurs, it can prevent proper water flow through the filter and cause your pool to turn cloudy more easily.

To fix this, you simply need to backwash the filter to flush away the particle build-up. You can do this by opening the top of the tank and removing the sand through a narrow opening. This can be a messy job, but it is necessary to keep your pool clean. After you remove the old sand, you can refill your filter with new sand using the same method you used to load it.swimming pool filter sand

For above ground pools, this sand filter system provides superior flow rates and energy efficient operation. The rugged tank is built with a durable, weather resistant, corrosion-proof material and is backed by a 1 year warranty. Inside, unique sand laterals ensure even water flow through the sand bed for maximum filtration. This highly efficient sand filtration system reduces your energy costs by enabling you to run your pump less and still maintain crystal clear water all summer long.

Unlike cartridge filters which use a flexible media, sand filters have a large basket that traps larger debris and can be easily cleaned by hand when full of leaves, petals, and other plant matter. Whenever the basket is full, you can simply turn the filter off, drain the sand and clean out the basket.sand filter for above ground pool

Sand filters are relatively simple to operate and maintenance is even easier. Typically, the only thing required is to occasionally backwash the filter when the pressure on your pressure gauge starts to rise indicating that the filter is getting full of particles that are blocking proper water flow.

Sand filter systems can be found at most hardware and home stores. They are also widely available online and many manufacturers offer a variety of sizes to fit any size above ground pool. When shopping for a sand filter, keep in mind that most are designated by both the physical size of the tank as well as by weight which is how they are sized (like 200 lb filter). This can make it difficult to compare products until you have narrowed down your search.
