OK, here's a bunch of data to mull over.......I decided to check the pressure of everything after getting a new water meter installed on Tues. Presuure at the closest bib to the supply is 50 psi. If I turn on the kitchen faucet, which is about 10 ft from the source, it drops to 45 psi. When I turn on the sprinkler system, pressure drops to 30 psi at the lowest with zone 4 on, and 32 psi for the other 7 zones. Zone 4 is the one that is causing the most problems and the range for each head is about 18 ft. Oh, and there are 5 heads in this zone. The heads are Rain Bird rotary heads. The system is about 10 years old.
Other zones with the same style heads have ranges from 21' to 24'. Some have 4 heads, one even has 6 and still gets 24' distance. Zone 3 has 4 rotary heads and two spray heads and the range is 21' for two and 18' for the other two. (I assume that the two going 18' need to be cleaned out.)
Checked the neighbors hose bib closest to his meter and it's 48 psi, so I guess I'm getting as much as everyone else in the area.
So.............based on this I'm guessing that I either have a bunch of spray heads that need to be cleaned or that there is possibly a faulty valve? What else do I nee to check? The supply line from the street is copper and has an outside dia of .901' which would indicate 3/4". The line from the meter to the sprinkler system is 1" copper.
Thanks for any help that you can give!
