Hello, I used the Gardena garden planner to design the irrigation system with sprinklers, as shown in the picture. Does anyone have any tips? Would this setup be practical, or are there any improvements you would suggest?
Has anyone already installed this system and can share some advice?

illusionslos27 Aug 2019 13:54I have Hunter and had it designed by a company. That cost me 80€ (about 80 USD). I thought it was worth it. I installed it myself, using the plan and a discussion with the company.
For a simple rectangular area, I would have planned it myself, but our layout is a bit complicated and surrounds the entire house.

Use Hunter or Rainbird.
There are already several posts here about proper irrigation planning...
Your plan shows the usual mistakes. The sprinklers need to overlap each other.
Tell us where the water source is, flow rate...
Then proper planning is possible. So, we have an 8,000-liter (2,113-gallon) cistern with a submersible pressure pump connected. This will supply the irrigation system. According to my calculations with Gardena devices, the connection output is 80 (fills a 10-liter (2.6-gallon) bucket in 12 seconds).
As far as I could calculate, I would create three separate zones:
1. South garden with 4 sprinklers (south is on the left in the plan)
2. West and northwest garden with 4 sprinklers
3. Hedge with drip emitters and planting area in front of the entrance using drip emitters as well (of course, manual watering can also be connected)
I also planned the overlap as you suggested. The sprinklers could be from Hunter or Rainbird.
I would like the control system to be like the robot mower, managed via Gardena Smart app on the phone (Irrigation Control). For this, I would bury the three solenoid valves in a valve box (V3) in the garden, with the control unit located in the garage.
This is my current approach. What do you think?
@Snowy36 We have made some progress now.
You have 3,000 l/h (about 792 US gallons per hour) at the tap. Calculate a maximum of 2,500 l/h (about 660 US gallons per hour) per zone due to pressure losses.
You are starting at the wrong point with your sprinkler planning. Each sprinkler has specific characteristics and water consumption.
For example, take a look at Hunter rotators. They have detailed lists of the sprinkler heads. I’ll send you the link via private message since linking is not allowed here.
You will need significantly more sprinklers. With your current plan, only some areas are being overwatered while coverage is insufficient elsewhere.
Based on your distances, mostly medium-sized sprinklers (MP2000) and a few large ones (MP3000) should be used. The MP2000 has a range of 4–6.4 meters (about 13–21 feet). Calculate with a maximum of 5.8 meters (19 feet). Place one sprinkler every 5.8 meters so that each one reaches the surrounding area. This is how you should distribute the sprinklers.
Next, make a list with the sprinklers’ range, angle, flow rate, etc. Then you can group zones that require a maximum of 2,500 l/h (about 660 US gallons per hour), wisely arranged by area.
The advantage of this system is that you can also use smaller heads (strip patterns or MP1000) for short distances. The precipitation rate remains consistent. It is best to use housings with pressure regulators—just one type of housing with different heads that have adjustable angles within certain limits.
Using smaller sprinklers with lower water consumption allows you to connect more sprinklers per zone.
Without detailed planning yet, two zones for the lawn might be tight. I think you’ll need three zones plus your drip irrigation for the hedge. So a valve box with four or better five valves.
Choose one with an air pressure connection so you can drain the system in autumn.
Hunter, for example, offers Hydrawise irrigation controllers. They have both app and web control. Simple, compact, and reliable.
If you have more questions, just ask.
