Do we provide a warranty?
Most irrigation components supplied by leading OEMs are covered for several years by the manufacturer’s warranty, but irrigation contractors are not required to warranty their workmanship. Ask for your contractor’s warranty in writing. PLC stands behind its work with a written and signed 2-year warranty and honors all manufacturers’ equipment warranties.
Our business is built on a few basic principles. First, we build irrigation systems that minimize clients’ total cost of ownership—installation, maintenance and repair—over the life of the system. Second, we treat our clients as we would like to be treated. Explain the pros—and the cons. Be responsive. Honor your promises. Fix your mistakes. Be friendly. We have hundreds of long-term customers that are happy to share their PLC experiences with you. We encourage you to click through our website and learn about underground irrigation. If you have any questions, please give us call.
How does a sprinkler system work?
Most underground sprinkler systems are connected, as is your house, to either the public water supply or to a well. The sprinkler system’s main water line is further segmented into a number of separate irrigation zones comprised of several rotor sprinklers, pop-up sprinklers or drip lines. Each zone waters a particular section of the yard. A number of factors dictate the number and type of zones required. Factors include the size, slope and composition of the landscape, as well as the water pressure and flow rate.
Electric valves regulate the flow of pressurized water into each zone from the main line. The pressure of the water is sufficient to force the sprinkler heads to pop-up and rotate, depending on their function. Each valve is connected by low voltage wires to the system controller (or clock) that is typically mounted on the side of the house. The controller is programmed to open and close each valve at a specific time, for a specific amount of time, on specific days. Rain sensors measure the amount of natural rainfall and signal the controller to reduce or cancel the sprinkler cycle if Mother Nature has been doing her job.
Regulations & Permits
A permit from your municipal or county government is required for installation of a secondary water meter for irrigation systems. The permit fees vary by jurisdiction. The overall billing rate for water from the secondary meter is lower because the sewer rate does not apply. The water flows into the environment and not back into the sewer system.
A backflow prevention device is required for every irrigation system connected to a potable water supply, public water system or well. The backflow preventer must be certified by a licensed plumber when the system is first installed and then the local water authority must inspect it. In addition, the municipal authorities require an annual re-certification of the backflow preventer to safeguard the water supply.
Regulations also require a rain sensor on all new irrigation installations. The rain sensor prevents the sprinklers from turning on when there is sufficient natural rainfall. This regulation is designed to conserve water.
PLC and our partners obtain all the required permits and arranges the required inspections at cost for its clients. We have a licensed plumber on staff to conduct and submit the annual backflow certifications to the local authorities.
