needs ideas to finely control drip rate
I have a situation where I need to restrict the drip rate of a subsection of my drip irrigation system. Unfortunately, I don't have the option to place the subsection on a separate watering schedule. I have a 5/8" mainline with four 1/4" lines w/ emitters that makes up the subsection.
I need to drop the drip to about 20% of the current rate. I'm at a loss for a good way to do this. I'm thinking a fine needle control valve spliced into the 5/8" line would do the trick, but I don't know exactly buy at the hardware store.
Anybody got some ideas?
