Hayward PoolVac Ultra Flow Gauge (V574P)
The flow gauge is a replacement part that was made by Hayward. The same high-quality materials were used to manufacture the original factory part. Making this a genuine OEM product.
This flow gauge was designed to help you program or adjust the flow of water that comes from your pool pump to the suction cleaner. Allowing it to perform at its maximum capabilities, sucking and pulling dirt, debris, and other forms of mulch off the surface of the pool.
This part is made from a clear plastic compound with a spring that runs up the middle and has a black tag on the top end. It attaches to the end of your cleaners hose assembly so that way you can accurately check your suction. When adjusting the flow of water, you want the black tag on the top to be sitting in between the minimum and maximum indicator, this means it is set at the desired flow required for the cleaner to operate correctly. If the gauge is set below the maximum indicator then the flow is too high, if it's sitting above the minimum indicator then the flow is too low, so you may have to make a few adjustments with your pump and or filtration system to correct this issue.
