Hi,
This is a very broad ballpark question. We have about 18 rotary Hunter sprinkler heads for larger areas of our lawn and about 12 Rainbird static heads for smaller areas. Here's what the watering session looks like:
6 rotary heads run for 35 min
6 rotary heads run for 35 min
6 rotary heads run for 20 min
6 static heads run for 10 min
6 static heads run for 10 min
After the system is done running it uses over 3000 gallons of water in a single session. Does this sound right? This is about what we use during the entire month in winter!
A gentleman who owns an irrigation company told us the system with these heads should use from 1800 to 2200 gallons per session. He didn't see the actual system, we just exchanged emails through a mutual acquaintance. He recommended inspecting our system for leaks or checking the seals on the heads.
We checked for leaks, and didn't find any. The water meter stays still if the system isn't operating. If we leave the house and spend a few days elsewhere and no water is used at all, then our meter would stay on the exact same mark as we left it. There are no soggy spots anywhere in our lawn after watering it. So unless the leak occurs deep under ground during the 110 minutes when the system is actually running, and the 5-gallon-per-head average rule is correct, then 3000 gallons should be correct. Or is the gentleman right about 1800 to 2200 gallons?
We can reduce the flow on all those heads to get it down to 1800 gallons, but then the lawn would receive very little water. Far less than recommended 1 inch. Actually it already gets a little less than that. What are we doing wrong?
Thanks for your help!
