Selecting an Irrigation Contractor
-
A good irrigation system is one that will take several factors into consideration. It should provide uniform head- to -head coverage. It should provide for climate controls such as rain, freeze, moisture, and wind sensors. It should be easy to maintain and to adjust for seasonal changes. It should promote efficient and conservative use of water.
-
The standard manufacturers and contractors warranty for most irrigation products and installations is one year on materials and workmanship. Ask for references.

State law does not require a contract. However, a responsible contractor should have no problem with an agreement that outlines the scope of the work, price, payment arrangements, and warranty period.
-
A copy of the “As Built” design should be required of the contractor. This will benefit you when making changes in your landscape or for irrigation system repairs. A design is not required for bidding.
-
Most water authorities require permits and inspections on all new irrigation system installations. The irrigation contractor may also be required to register in each city before he/she is allowed to obtain permits or call for inspections.

Several documents should be provided to the irrigation system owner:
Manufacturer’s manual for the automatic controller;
Seasonal watering schedule;
List of components that require maintenance and the recommended frequency of service;
Irrigation plan showing the installed system; and
Maintenance checklist.
The Maintenance Checklist contains:
the signature of the irrigation system owner or the owner’s representative;
the irrigator’s seal, signature and date; and
a statement, “This irrigation system has been installed in accordance with all applicable state and local laws, ordinances, rules, regulations, or orders. I have tested the system and determined that it has been installed according to the Irrigation Plan and is properly adjusted for the most efficient application of water at this time.”
Don’t forget: To place a permanent sticker that has your name, license number, company name, telephone number, and the dates the warranty is valid on the automatic controller. No automatic controller? Put the sticker on the original maintenance checklist.

If the irrigation system’s owner or owner’s representative is unwilling or unable to sign the maintenance checklist, the irrigator should note the time and date of the refusal on the irrigation system’s owner’s signature line. Keep a copy of the maintenance checklist and note the date that the documents were delivered to the irrigation system owner/designated representative.
