Hi, i am putting in a sprinkler system and i have a few questions. I have 60 PSI, a 1 inch main water line, about 17 GPM and my water is from irrigation. I am going to us 1" poly as my main line to my 4 valves and you use 1" latter lines to my sprinkler heads. I was thinking of using Rain Bird 32SA rotor heads all through out my yard. I noticed that the insert of the sprinkler head is only 1/2" thread so i would be using a 1" X 1/2" elbow insert. Will i lose presure using the 1" X 1/2" elbow insert with the 1" poly? or should i go with a bigger sprinkler head with a 3/4" thread and use a 1" x 3/4" elbow insert?
The reason i didn't consider the Rainbird 5004 was becuase i don't need the 25'-50' range, that's way to big for my yard. I need something like 15'-32'. If I use the 1" X 1/2" elbow will i lost pressure if so how much? will the 1" x 1/2" affect my sprinkler systems performance.
You might want to look at MP-Rotators. The MP2000 throws 13'-21' while the MP3000 throws 22'-30', and you can mix and match the two on one circuit. They use standard spray bodies, with the Rotator replacing the spray head.
