I have a couple of drip lines each about 15 feet in length. Some emitters are installed directly in the main line and others are on short lengths of 1/4 " tubing that then attaches to the main line.
I'm having trouble regulating the pressure. The small pressure regulator I bought seems to have no effect and it's easy for me to get fountains of water spurting even from 1/2 gallon per hour emitters. I don't think that's what "drip" irrigation is supposed to do.
Most puzzling is that in one line I noticed that little water was coming from an emitter about half way down the line, even though all those beyond it were doing well. So I pulled the emitter out of the tubing and the flow through the hole did not seem much different from the flow through the emitters.
I'm looking for suggestions about how I might get this to work better. Thanks for your attention.
