You use the orifice size of the sprinklers that you are testing. You install full port ball valve in a drain pipe from each of the sprinklers you are testing with the correct orifice. If you contact Cobb County, GA you can get their procedures if you are interested.

What kind of variance in calcs from actual bucket test results are considered acceptable? I'm just curious since taking out the head and flowing straight from a 1/2" threaded outlet vs. flowing a 7/16" orifice (like a 4.2k sprinkler w/ element removed) could possibly work in your favor to a small degree but could also work against you depending on what k-factor of sprinkler you used. In a 13R bucket test do you actually remove more than one sprinkler and flow up to four? Or is it always just one? Seems like a source calc w/ one sprinkler flowing would make more sense if you're only required to bucket test one sprinkler... -B- On 4/9/08, Todd Williams - FPDC <[EMAIL PROTECTED]> wrote: > > If you have a really bad water supply, instead of a pitot you use a > 5-gallon bucket and a stop watch. 8-) > > > At 02:19 PM 4/9/2008, you wrote: > > > This is the first time I've heard it being done for 13R. 13D, yes.
