In this video Irritec USA and https://www.dripdepot.com explain an important and often overlooked part of any irrigation system, the filter. Filtration becomes very important if your irrigation water is not from a municipal source (meaning not the same water you drink) but instead from a designated irrigation source. Often new housing developments have separate irrigation water for the residents. This is good in that the water is much cheaper, however; the water is rarely filtered and if it is not properly filtered before entering your irrigation systems the particles will clog valves, drippers, spray heads and rotors. Dirty irrigation water will overwhelm a filter with a small surface area. So unless you want to constantly clean the filter screen the best solution to increase the run time and keep your system operating smoothly is to install a large filter that has a screen with a large surface area. Investing in a quality large filter will save you big money down the road in preventing clogs in your system that result in costly and time consuming repairs.
