Harmony Funny Pipe Lateral Line Drain� Features; Sizes; & Specifications
This valve offers you an Exclusive Turbulent Flushing Action that gives you trouble-free operation for the life of the system. When the pipes start to fill the ball will raise up and dance around inside of the housing. This creates a desirable Turbulent Flushing Action that flushes away sediment and dirt deposits. The ball changes valve seats every time the system is cycled.
The Pyramid Shaped Screen deflects sediment and dirt deposits away from the screen as opposed to having the dirt hammered into an ordinary flat screen.
The Wicking Pad is large and recessed protecting it from otherwise damaging sharp objects and rocks.
