If you are looking for a water restricting device, this is the product for you. Port size only 5/16" and hex/Allan key to boot for further turbulence. It looks nice, but that's about it
Very disappointed. Surprised AML would carry such a poor quality item. Poor construction. Port size only 5/16" of an inch - severely reduces water flow. If your looking to do any type of volume watering, forget about this product, it just doesn't allow enough water through it.
I made a irrigation system for my planer boxes and needed two water outlets from my hose bib. The previous dual turnoff system leaked from the start. It was all metal, and some might think that would be better. This unit has smooth well cut threads and sure off and on 1/4 turn shutoff. No leaks.
Before I bought the Dual Shut Off Valve I was able to talk to a service rep who assured me that the valve would work for my project.
