Water lines or kitchen systems can get gravel, deposits that break free, and other stray items in the line. The velocity of the water pushing them, they can severely damage or clog devices installed in the flow stream of the water line. A strainer is essentially a screen installed to allow water to pass through, but not larger items. The larger items fall to the bottom or are held in a basket for later clean out. They normally have an access that allows for them to be cleaned or have the strainer plate or basket replaced.

Strainers come is several different styles based on the needs. A plate strainer is the simplest, in which water flows through a perforated plate. Often the plate is corrugated shape to increase surface area. A basket strainer is a design where the strainer is shaped like a basket and usually installed in a vertical system. The basket strainer is easier to clean, since debris is captured in the basket. It can also sometimes offer more straining surface area than a plate strainer, improving flow rates, or decreasing pressure loss through the strainer.

Strainer elements are generally made from Stainless steel for corrosion resistance.
