Choosing An Irrigation Contractor - Questions To Ask
The success of your irrigation system depends largely on the contractor you choose to
install it. A contractor's expertise and specialized skills are crucial in determining your
systems efficiency and long term reliability. In fact, how your system is designed and
installed will make the difference between a system that is reliable and keeps your lawn
green and healthy, and one that is troublesome, wastes water and leaves your lawn looking
brown and unhealthy. Above all, you should choose a contractor who you can trust
and whom you feel comfortable.
To ensure that you hire a reputable irrigation contractor capable of designing, installing and
maintaining a high quality system, ask the following questions:
**Mandatory Irrigation Contractors License**
Koster Irrigation is a NC Licensed Irrigation Contractor.
Does Your Contractor Have A Minimum Of 10 Years Experience?
We have been in business Since 1994 Designing, Installing and Servicing Residential
and Commercial Irrigation Systems.
Does the Contractor Have Appropriate Insurance & Bonding?
Does The Contractor Offer A Warranty Period?
Koster Irrigation's Warranties Include:
Can the contractor provide a list of references?
Client references are often the best indicators of the contractor's work. At your request, your
contractor should provide you with the names and telephone numbers of references to call.
These property owners can attest to their satisfaction with the contractor's work.
Koster Irrigation will proudly provide you with references upon request.
Is a rain sensor included in the contractor's estimate?
Rain sensors are designed to shut off the irrigation system when a specific amount of
rainfall has occurred. These devices conserve water, save you money on utility bills, and
prevent unnecessary wear on your sprinkler system. Koster Irrigation includes the
installation of a rain sensor in all of our proposals. We are constantly amazed as to how
many irrigation installers forget this item.
Is your contractor certified to test backflow preventers?
Backflow preventer devices are required on all city water irrigation systems to protect the
drinking water from contaminants. Certification is required by law to install and test these
devices.
Koster Irrigation is certified by the City Of Wilson, Rocky Mount, Goldsboro Utilities to test
backflow preventers. We test an average of 300+ devices annually. Residential backflow
devices are due every other year, commercial properties are due for
inspection annually.
Does the contractor use waterproof wire connections and valve
boxes?
Some of the most common electrical problems in an irrigation system are caused by faulty
wiring. Special watertight connections are necessary to guard against short circuits and
prevent corrosion. Valves should always be enclosed in protective boxes that allow for
future inspection and maintenance. You would be suprised at the amount of contractors
that miss this important step.
Koster Irrigation always uses heavy-duty, grease filled splice kits to safeguard the
underground electrical connections. We always install valves in protective boxes that
provide easy access.
