I just finished setting up my drip system and have a question about which drip emitters most people use. I have rainbird 1gph emitters, but I just finished testing them and they are no where near 1 gallon per hour. I put the drip emitter into a one gallon jug, and it was half full in 5 minutes. So my emitter appears to be running around 6 gph right now. I tried 4 other 1gph emitters from the same package and they all ran about the same. Anyone have any ideas what I am doing wrong, or suggestions for other emitters to try?
Just some background info- my drip line runs from a faucet connection, through a 25psi pressure regulator, through about 25 feet of 1/4 tubing, into a 5 micron sediment filter, and through 2 carbon filters before the emitter is attached. The faucet valve is only open half-way, and I also have a ball valve before the 1/4 tubing reaches my carbon filters, and this is also open only half-way. I thought that doing this would reduce the pressure a little more so that maybe the emitter would function as 1gph, but it hasn't seemed to help.
