Sprinkler System design help

[TXSTDU]

What do yall think the best solution is?

Option A: Sprinkler heads that use less GPM and a lower precipitation rate (the ones I am looking at is .12 in/hr) requiring less zones but a longer run time

or

Option B: Sprinkler heads that has a higher GPM rate and a higher precipitation rate (.56 in/hr) but needing more zones but a shorter run time


I am thinking option a as a cost cutting measure but I am looking for some of yalls professional opinions.

I start my sprinklers in the spring every other day for a short time on each zone, and gradually go up as needed throughout the summer. So that being said I don't think one would make a difference over the other because I am just watering what I need to keep it green.

You can go to rainbird.com and get graph paper and draw deminsions of your yard and send it to them in a email and they will desicion a system for you and tell you what heads you need. I don't know if this will help you make a desicion but it may help

Would the longer run times of option A ( electrical cost) out way the savings in the materials going with less zones?

That is a question I have no answer for. In the long run probably I just don't how far in the future the breakeven would be.

The two or three extra zones isn't a big issue I am just more interested in doing this right.

To speak of the electrical cost it minimal. It's a 24 volt system @ less than 1 amp. The water cost per minute is more than that.

The decision for whether the go high flow or low flow really depends on your water supply to the house and the PSI at your water faucet. Low static pressure at house, you need to go low flow.

I tried that and they never respondents to me.

My buddy had Rainbird design his and they designed a 28 zone system, lol. Low flow He ended up with a 6 zone system. A low flow system will cost a lot more up front.... Lots more heads and a much bigger controller for all the extra zones
