Quoted from "Wet_Boots" Make the tie-in first and then measure what is produced - that way you assume nothing. Then you can design your system. Wet_Boots Thanks for this suggestion. My plan was to have the backflow installed and then test for GPM and pressure. The design specification is all done. All I need to do is to verify GPM and pressure. I am meeting with the local expert today to go over details.
Pass-1 Thanks for all of your advice. I am working with a local specialist with lots of sprinkler installation experience in the area. He has done a few plumbing upgrade for me already. He did say the pumps used in the area are generally 1 HP and I should expect aboyt 13 GPM and be lucky to get 15 GPM. My plan was to have the backflow installed and then test for the actual GPM. He did tell me about raising the pressure settings on the pressure switch. As far as the othe questions concerning the ...
I have a well pump on my property and a pressure switch (on 40 PSI off 60 PSI). I have tested my static pressure to be 48 PSI using my outyside spigot (on 1/2 copper pipe). I do not know my current GPM , but based on 1" inlet pipe, am guessing about 15 GPM. I am at the planning stage for my irrigation system (0.92 total acre). I plan on having my plumber install my backflow preventer and then I will install the system myself. Short of knowing my working pressure and my GPM, I want to make the fo...
