If you want your irrigation system to be functional for a long time, then yes, you need a filtering system that will keep the foreign particles away. Now, one night argue here that they can as well use sprinklers instead of filters. But in my experience, sprinklers are also made of some form of filtering system to prevent your irrigation system from getting clogged up with solid particles. In this article I will tell you about the different types of filters available in the market and which one you should choose for yourself.
But first let me ask you a simple question: what do you think will happen if you don’t have a filter? Small particles of sand can enter your system and cause wear and tear in it. Sand particles can enter the small water passageways and clog them. Even if a tiny grain of salt enters a spray nozzle, it can result in a dry, dead spot in a lawn. And remember that sand is not the only thing that can enter in and damage your system. Organic materials such as algae can grow on your system, causing problems. So to prevent any or all of these mishaps, you need to install a filter for your irrigation system if you want to keep it well maintained and free from harm. Below I will give a brief description of the different types of filters available and their functionalities.
1. Screen filters: Screen filters are the most common types of filters available in the market, and they are also the cheapest ones. Screen filters are great for removing hard particles such as sand. Unfortunately, they cannot remove organic materials such as algae and mold from your irrigation system; so they are not full-proof.
2. Cartridge Filters: Another type of filter available is cartridge filter. These filters are made up of paper and hence they are good enough to remove not only sand but also organic materials such as algae. While you can wash some type of cartridges, others will need to be replaced by new ones when they become dirty.
3. Media Filters: Media filters are yet another type of filtering system available. Media filters are made up of a solid, sharp-edged “media” which filters both sand as well as organic materials. In most cases, the “media” is nothing other than crushed sand. It contains a number of small spaces in the grains and water is forced to pass through these spaces. This way debris is stopped when it cannot pass through these spaces.
But now the million dollar question remains: which type of filter do you need? It really depends on your budget, the kind of filtering system you want, and also the quality of water available in your area. If you live in a city where water contains nothing more than grains of sand, you will do well with a screen filter. Screen filters are also the least expensive. If you want a more hardcore filtering system then of course you need to look for the more expensive ones. In some cases, you will need a combination of more than one type of filter.
