What is a Y Strainer used for in irrigation piping?

• A. Perforate pipe with arrangement that allows water entry and filters debris.
• B. Increase flow capacity.
• C. Act as a check valve.
• D. Act as an air relief valve.

Answer: (A)

A Y strainer is a filtering device placed in-line that removes debris from irrigation water. As water moves through the Y-shaped housing, a screen captures solids like sand and silt, protecting downstream components such as valves, pumps, and emitters. A cleanout or drain at the bottom lets you flush out the captured debris, keeping the system flowing smoothly. This describes an arrangement that allows water entry and filters debris, which is exactly what a Y strainer does. It isn’t used to increase flow capacity, act as a check valve, or function as an air relief valve, which is why the other options don’t fit.
