Very useful in any plumbing system, these valves allow the removal of debris without turning off the system. Y-Strainers are commonly fitted in the field with nipples and drain valves to permit the strainer screen to be cleaned while the system is operating. Open the drain valve with the system still pressurized and the debris trapped in the screen is eliminated through this connection. Nations WareHouse offers durable Y-Strainers to help reduce system shut-downs for cleaning and maintenance.
