Went to OSH (local homeowners/garden place). Only hose they carry was so crappy, it split even before using. Tried Home Despot. Carried same brand. Decided to revert to previous M.O. : PVC pipe, capped at one end, other end equipped with hose junction. Small holes punched at intervals. Remember, you'll get a significant difference in amount of water leaked or sprayed at the beginning compared to the end of the length. You may want to do an experimental run, and plan on drilling more holes towards the far end of the run once you've seen how the pattern you've drilled behaves. FWIW, I buried some of what I call "ooze hose" -- it looks foamy -- http://www.groworganic.com/1-4-mr-so...-100-roll.html under mulch and it lasted for many, many years. In clay soils, I like the laser drilled 1/4" tubing. And don't forget a backflow preventer. Why? David If there is sufficient pressure in the system -- beyond the connection to the hose bib -- it is possible for there to be backflow into your household water line. Soil and soil organisims can enter the system through the holes in the PVP pipe when the water is shut off. Thus, there is a possibility of contaminating the household water supply. In general, a system as proposed by Higgs Boson should have a backflow preventer, sometimes known as an anti-syphon valve. The building codes in California (where Higgs and I both live) require it. In my garden, I paid a landscape contractor to install a fixed irrigation system with underground pipes supplying above-ground sprinkler heads. I have a total of 9 valves for the flat areas and 4 valves for the hill, with 13 anti-syphon valves. The same contractor also designed and installed the landscape. -- David E.
