Well, my UPS driver, who is also a good friend, has been admiring my irrigation system since I put it in a couple of years ago. He asked for my help in doing his. I went over to his house this evening. Suburban subdivision of 30 year old 2,000 to 3,000 sq ft. houses. Water meter is located very accessible in the front yard. I took my pressure gauge, and at the hose bib on the house closest to the meter, it measured 60 psi. That sounded good. Then we did a bucket test for flow. I got five gallon in 50 seconds - 6 gpm -- none too impressive. The run from the meter to the house is about 50 feet and I didn't go into the crawl space to see how convoluted the run to the hose bib was. My question is, should I wait to lay out the zones until I make my POC connection and do a flow test there, or should I assume that the 6 gpm is what I have to work with? No basement, so like most of the yards in the neighborhood, I will have a double ball check valve and POC right after the meter.
