We're new at irrigations and have installed a few small systems without any problems. Used some assistence from the local supplier on the first install but after that, the others we did were prety strait forward. I have an opportunity to pick up a few larger properties 1 acre + and have a few questions. The pressure on the system is 120-124 psi, and the meter is inside the house. My first questions is for those in the DC area. Apparently WSSC offers a submeter, for irrigation use. Can anyone recommend an installer? My second question is, since the customer has a lot of pressure should I plan to install some type of water pressure regulator? There is a long supply run of about 250'-300' to get to a section of the property that is 120'x50'. All of our other jobs to date have been on properties 1/4 acre or less with 75-85 psi pressures, and we have used 3/4 pvc for supply lines. We plan on using 1" lines with project unless we should go larger. I will be talking with the local rep this weekend for some additional guidance. Thanks in advance for your help.
