    Default Drip Irrigation Help!

    I put together a drip irrigation system that looks as follows.
    1 - From a garden spigot => small lead hose => multi connector manifold => timer valve (attached to an orbit timer) => 20 psi pressure regulator => pvc adapter => hose connector => 1/2 inch drip irrigation hose => connector => 1/4 inch drip irrigation tubing => 1/2 gph red drip emitter.

    2 - The half inch tube runs around the garden as follow

    26 feet straight (part 1) => elbow connector => 5 feet (part 2) => 30 feet straight (part 3).

    3 - I have for 1/2 gph emitters towards the end of part 1 and one sprinkler type emitter towards the end of part 3.

    When I turn the system on (I have the spigot turned on only ust a little bit), either manually or automatically for 1 minute..the 4 1/2 gph emitters are spraying a stream of water instead of dripping.


    What am I doing wrong?

    Thanks

    Here is a picture of the system.

    YOU can't do anything "wrong" with a drip system. Either the emitters need to be adjusted or they are defective, or they are designed to emit a "stream" in order to deliver that gph.

    Are you using feed-through emitters, or end emitters?

    Another item is water pressure. ALL MY lines that come off of the house lines have one.

    He has a flow control pressure regulator at the connection to the water line. The thing he DOESN'T have is a backflow preventer on the hose faucet, which is a universal requirement.
