Irrigation filters are a vital component of an irrigation system.
Filters are designed to keep irrigation systems free from debris such as sand, dirt, algae and other particles that can clog the sprinkler heads, negatively affect the system's overall performance and leave you with dry plants and an unhappy customer.
There are a variety of filters out there to prevent solids from accumulating and disrupting the irrigation systems, including screen filters, disc filters, media filters and centrifugal filters.
“Discs are one of the more universal filters and are good at catching organic and aggregate or sand matter,” says Justin Crocker, owner of Earthtones Greenery in the Dallas and Austin markets.
“They can be, in my opinion, used for almost any application. Screen filters are good for catching sand and rocks, but not for catching organic matter that can grow inside pipes and valves.”
The choice of what filter to buy depends in large part upon the condition or quality of the water as well as the water source, and regional differences abound greatly. Water pumped out of a lake, for example, may carry organic matter or rocks, while water pumped out of a well can produce sand.
Crocker says in Texas, filters are not an everyday component of a regular irrigation system because most of their water comes from municipalities and cities.
Nonetheless, he says in general, screen filters are the most common because they are the most economical.
