Pool Sand Filter Buying Guide

Pool filter

Here are some essential factors to keep in check when purchasing a new pool sand filter. We hope this will help select a suitable filter that is easy to maintain and to your liking.

Pool Size

When searching for a new pool filter, factoring in your pool size is an essential step. How many gallons does your pool usually hold? This is the question you should be asking before making a purchase. One of the general rules is, for every thousand gallons of water inside your pool, a square inch of filter area is required.

For instance, if your pool contains twenty thousand gallons of water, a 20-inch tank is highly recommended. If you’re not familiar with this, take a look at the guidelines provided by the manufacturer for your pool to get an idea.

Gallons Per Hour

If you have an active pool in your yard, chances are, you’ve heard of running the pool pump for about 10-12 hours in a day to maximize pool cleaning productivity. Hence, before you settle on a brand new filter, you have to decide on the number of hours you plan on running your pump.

Now, if you’re unaware of how to run the calculations, simply take the total vol. of water present in the pool and divide that by the number of hours the pump will run. The final number you get is exactly what you need. Note that, some sand filters do give out gallon specifications, so, read that as well.

Climate

This may not seem like an important factor but this is quite crucial in determining the kind of filter that will suit your pool. If you’re located in a colder region then, you may already know the effect cold and harsh water conditions will have on your pool. In such cases, it is highly recommended to look for sand filters that provide easy maintenance.

It is worth noting that, sand filters that are easy to install and drain during the winter for storage will offer better assistance. Picking up this type of model will also significantly increase and protect the lifespan of your filtration system.

Pool Sand Filter FAQs

Pool

Sand filters have existed for some time and this killer pool item has been the subject of many questions over the years. As such, here are some questions frequently asked regarding pool sand filters.

How Do You Change Sand in a Pool Filter?

Sand filters usually have a lifespan of 5-7 years but you may change it every 3 years or so while some may even require it to be replaced every year. Generally, for changing a sand filter, one would first have to drain the water out from the tank. Next, proceed with removing the filter head and then scoop the sand out from inside the tank.

Fill half of the tank with water and add the new sand following the manufacturer’s instructions. Continue by reattaching the filter head and then backwashing the water for about 30 seconds. Finally, turn on the filter mode and be sure to double-check for leaks.

How Does a Pool Sand Filter Work?

Sand filters are known to function through the movement of water from the top of a tank, all the way to the sand located at the bottom of a tank through high pressure. During the process, as water seeps in, the sand grains, containing sharp edges catch various particles like debris, body waste materials, and dirt.

Tiny and smaller particles are usually rid from within the water as they cycle through until eventually, the sand becomes denser and denser, after which, it has to be cleaned also known as backwashing.

How to Backwash a Pool Sand Filter?

Every sand filter makes use of similar basic mechanics and a typical filter system would usually offer 6 settings option, including backwash as well. Start by turning the pool pump off and set the valve to backwash, make sure it locks into place. Next, turn the pump back on and backwash for about 2 minutes.

Turn the pump off again and set its valve to the rinse setting. After this, turn the pump on once more and run the rinsing process for about a minute or until the water can be seen through the sight glasses. Finally, turn the pump off and start resetting the valve to filter mode, and make sure the handles are locked in place.
