what would be a reason to use a valve? Rather then a timer or is that a valve also... i guess i was curious as to what these Valves are http://www.homedepot.com/Outdoors/h_d1/N-5yc1vZbx82/R-100012407/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 My tap in is a line off the house that runs to the garage hose, i tapped into that and ran a blue plastic line to the garden at the garden i have a nozzle thing guess you can call it a valve, it turns water on and off and has a anti freeze ...
Im putting together my first drip system in my garden, trying to reduce weeds, and water. Question: my system is 1/2 inch, everything i see is 3/4 inch for back flow and pressure regulators. Is there 1/2 stuff out there? Also what is the purpose of a Valve?
