AI for irrigation supply distributors, tested on plans you already quoted.

Some specifications write you into the job. Western Michigan University's draft irrigation section says materials shall be purchased from the nearest authorized distributor of the specified products. Texas State University's standard says the product distributor should be engaged to make sure a controller's radio reaches the university's central computer. A plan set landing at your counter is where that starts, and the quote you sent afterward is the record of how your branch read it.

A label is often what a rebate turns on. EPA released its WaterSense specification for spray sprinkler bodies on September 21, 2017, and one for soil moisture-based irrigation controllers on February 11, 2021, and revised the weather-based controller specification to Version 1.1 in 2021. A program asking for a labeled product is asking about one model of one type. Your invoice names it, which puts your paper at the center of a file your customer has to build.

The federal index files you with farm machinery. NAICS 423820, farm and garden machinery and equipment wholesalers, lists irrigation equipment and agricultural and garden sprinklers among its entries. That single class spans very different buyers, so a sample should say up front whether it holds golf, municipal, contractor or grower work.

What you may sell can change at a state line. The California Energy Commission says that since October 1, 2020, spray sprinkler bodies have to be certified in its appliance database to be sold or offered for sale there, and that a regulator threaded onto the bottom of a noncompliant body does not count. Bodies made before that date can still be sold. A quote that works in one branch may not carry to another, and the draft shows what the document asked for. This describes the rule as the agency states it; it is not legal advice.

Certified designers are tested on all of it. The Irrigation Association's Certified Irrigation Designer program requires a four-hour, 150-question exam on equipment, hydraulics, scheduling, layout, electrical, maintenance and operations, plus a specialty exam in golf course or landscape irrigation. Plans drawn that way assume a reader who knows what each symbol implies, which is the part a new counter hire has to learn.

Public buyers bring forms of their own. San Antonio's annual contract for sprinkler and irrigation repair parts, opened April 21, 2025, asked for a discount by manufacturer along with the type of price schedule, its number and date, and the column that discount rests on. Three categories were deleted by the time bids were tabulated. That form sits third on the list above.

One limit covers every job. Nothing here touches your ERP, a live quote, an agency portal or a customer's account. Nothing designs a system, substitutes a product, decides eligibility or submits a rebate. A person at your branch approves every quote, and your customer submits every rebate.
