adding to a drip line
I have an existing drip line (1/2 inch line of Rainbird emitter tubing) that runs around the perimeter of our house. I want to add some 1/4 inch feeder lines to extend the reach of the irrigation into the beds. From what I have gathered, I will need a hole puncher, barbed coupling, 1/4 inch tubing and a goof plug cap.
My question is what kind of emitter should I use? Should I use a "bug plug" instead of a goof plug to allow a drip at the cap? I see there are 1/4 inch emitter lines and mini in line drippers as well, but these do not appear to be pressure regulated. If you have some experience and can recommend the correct set up, I'd appreciate it. Thanks.
