First Flush Washers – Black
Slow release valve set for diameters 0.25mm - 1.0mm. This is for slightly slower draining than the red, K0002 washers.
The smaller the size, the slower the water will drain - this is the perfect solution where you have a smaller first flush diversion chamber or if you want to perform first flush diversion less often.
