So today we started connecting bits of our drip system, and we got a rude awakening. We ran a 1/2" mainline down the length of the garden, and in the first bed we ran 2 12' lengths of 1/4" tubing, with holes spaced a foot apart. Well. When we turned on the water, what appeared before us was an exponentially decreasing water pattern. The first hole spurted water several feet in the air, while the last hole was completely dry.
We did a variety of experiments to attempt to remedy this, and none of them worked. It seems as though we should have bought the much more expensive pressure compensating tubing, which maintains even water pressure at each emitter. Is this the only solution? Is this a situation where our DIY determination and cunning cannot save us?
