Depending on your location, you will have different fees and taxes related to irrigating your property. We can help you no matter where you are in our service area.
What To Look For
Be informed…Ask questions!
A good contractor will encourage you to ask questions and then provide you with all the information you need to make an informed decision. You need to know exactly what you are getting for your money and what to expect out of your irrigation system.
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.
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.
Greenway obtains 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.
