Hello! I’m wanting to DIY my irrigation system. Not only to (attempt) to save money, but also, I remember how frustrating it was for my dad to try to repair sprinklers without knowing where everything was and how it was set up. I’m running into a few issues. I would like to know what to do myself and what I should hire for.
Goal 1: Zones and Lines
I have the yard planned out. I have my water needs notated out and color coded. The whole lot is ~18,330 sq ft. My GPM is ~8.6, and my PSI is ~58. I’m needing help mostly with the lines and zones. I also don’t know if my plan is even a good idea or possible haha. I would love some feedback on it.
“Green areas are for high watered needs like trees. I will want drip and spray irrigation to these areas. Yellow is for medium watered needs like shrubbery. I will want drip OR spray irrigation to these areas. Not both. Blue is for high watered needs for ground cover. I only want sprayers for these areas. Orange is for low water needs like grow beds. I want drip irrigation for these areas. Gray is for areas that do not need to be watered.”
Goal 2: Prep
After the plan is confirmed, I know I’ll need a material list. I feel pretty confident in my research on this and getting a parts list etc. I would love any input or advice on prepping when it comes to parts. I know certain parts can also go into the planning of goal 1. Any guidance here would be awesome.
Goal 3: Install
I have people that can dig and trench, but I need a plan to show them. I also have pictures of the backflow prevention and what is required.
“…you have has a PI connection stubbed into it. If you are connecting to the PI then you aren't required to have a backflow protector. There has to be a physical air gap between the culinary water and the PI water. We the city would have to come and inspection this connection after the work is done. Attached is a diagram of what it should look like after it is connected.”
Looking at my box outside, I’m still confused by what the city guy is saying and what part I need to do. Any clarification would be appreciated!
Additionally, the yard is going to be a work in progress for the next few years, but getting the irrigation in, is something we are hoping for before the end of October. Does this make sense? Is this a good idea and timeframe? I mostly only have weekends to work on it, but can have people trench when they’re available which will be more than me. Suggested timelines would be super appreciated in accordance with zones 6b and 7a (I know that’s growing zones but I didn’t know if it would be helpful to get an idea of the type of weather we usually have.)
Goal 4: Maintenance
Any suggested maintenance or other things I should take into consideration would be very helpful.
Thanks so much for your time and reading. I’m also open to freelancers if you think you can save me some money and time by getting this drawn out for me. I don’t think this goes against the rules, but if it does, please let me know and I will edit it immediately.
