From each supplier's own site on the date in the sources; call your branch before you plan around it.
Your counter list
The items irrigation contractors buy every week, from the van stock on our tools list. Ask each supplier for a price on these first; they decide which account saves you the most.
| Item | Why it is on the list |
|---|---|
| Spray heads, rotors and nozzles | Repairs |
| Valves and solenoids | Repairs |
| PVC and poly fittings | Line breaks |
| Glue, primer and wire connectors | Every repair |
| Controller and spare timer | Swaps |
For the first order, price the starter kit too: trenching shovels and a sod spade; pvc cutters and poly pipe cutters; multimeter; valve locator or wire tracker; pipe pullers and funny pipe tools; pressure gauge; marking flags and paint; utility trailer. Bigger purchases to price at a dealer or rental house: walk-behind trencher; vibratory plow; air compressor for blowouts; backflow test kit.
Opening a trade account
Bring your business name, tax ID and license number, and a credit application if you want terms. The big-box programs are compared row by row on Home Depot Pro vs Lowe's Pro. For the tools themselves, the irrigation tools list has prices read on the makers' own sites (Fluke).
When supplier prices change
Update your irrigation price list the same week a supplier raises prices. In Koira, that price list is what your estimates are built from.
