Does any one have the specs for funny pipe? I have been using the Rain bird 1/2" I would like to try assembling some swing joints to get used to doing it before I go out to the site. Also I would like to have a comprehensive number to use as far as friction loss figuring the additional fittings and the pipe. Does anyone have an idea of what the additional friction loss would be with 4 swing joints per zone assembled opposed to just using cutt- off rizors. Lets say were using 45psi dynamic pressure at 12 - 14 gallons per minute on 1 " lateral line... Let me know if this is not clear enough.... Where has everybody been lately.. am I the only guy with questions... I am getting flash backs of my algebra teacher saying " remember the only dumb questions are the ones that arent asked" Oh buy the way I ordered my study guide materials to prepare for the CIC exam in February... SEEEEEEEEEE Yaah !
