Don't buy another expensive timer or build a complex manifold! Simply attach our hose threaded Galcon Alternator Valve to your spigot or timer to instantly double coverage of your drip irrigation system.
This Alternator Valve is not a timer, and does not require batteries or a power source. It is simply powered by the water moving through it. Place the Alternator Valve downstream of a timer or valve and it will alternate the water flow from one outlet to the next with each timer cycle. It is a simple, inexpensive solution to double the coverage of your drip irrigation system.
