Quick Coupling Valves (sometimes called quick couplers) help add versatility to any irrigation system. Everyone home and business should take advantage of the convenience that quick couplers afford. Quick Coupling Valves are generally installed on the main line where there is constant pressure. With the use of a hose quick coupler valve you can easily attach a hose at remote parts of your yard instead of relying on the tap near your house. We always recommend installing a quick coupler at each valve box. Quick couplers are one of those "inexpensive extras" that go a long way to adding convenience to your sprinkler system.
