Lawn irrigation

have done twice. Rain bird will design for you if you send them a plot drawing with dimensions of what you're wanting to irrigate.Go to the rain bird website.

I did my front yard last year, and just did my backyard this year. Last year I bought the rainbird diy kit from home depot. It came with 6 heads, a hose end timer, and 150' of poly tubing. It was pretty easy to install.

This year I did my backyard, which is oddly shaped. I am using 4 orbit pro grade rotating heads, with 1/2" PVC. I will not be able to have much overlap in the spray, so I will just run the system longer. Both times were pretty easy install. You can rent a trencher from home Depot for $75 for 4 hours.


Now, at some point I will probably install real valves instead of the hose end timers, but that will be down the road a bit

The issue with spray overlap isn't just about rate of watering for a zone. Running it longer doesn't necessarily address the issue. The main issue is heads aren't design to throw water down at their base. It is too difficult to design a spray to deliver water straight down that won't over saturate compared to the rest of the covered spray area. The point of overlap is you need the sprinkler to deliver the proper amount of water to the base of the adjacent sprinkler heads because they can't water their own base.

Will the system not work if overlap isn't possible? Of course not. It is just the difference between getting a well performing, optimal system vs something non-optimal.
