Join guest speaker, Jeff Satterwhite of Centerline Development (www.gocenterline.com) as he talks about Irrigation, how it works and why it is necessary.
Backflow Preventer – Once water has passed through this system, the Backflow Preventer stops water from flowing back from irrigation lines into city drinking water
In this particular area of NC irrigation and drinking water comes from the same source – so in the case that the main line is cut somewhere down the stream the valve creates a siphoning effect that prevents the water that has been in the yard or the yard lines from getting into the drinking system.
An Insulted box must go over the backflow preventer because it will freeze in the winter. Another option would be to remove (shut off) the Backflow Preventer during the colder times of year when freezing can take place.
The cost of a Backflow Preventer is around $300-400 (which is why you want to protect it during freezing temperatures)and it requires installation by someone certified. The Backflow Preventer must be inspected every year by certified inspector to make sure it is working properly.
The control valve – There are a multitude of control valves we use – we mainly use Rain Bird and Orbit. A timer can be set up in a wide variety of programs such as multiple time zones, multiple areas of sprinkling and multiple times of day. This would be for the purpose of going on vacation or hotter/colder times of year.
A dedicated line runs back to the panel so it wouldn’t get tripped off in case there is some other type of GFI trip in the house it won’t cut off irrigation.
Control valves in the box will open when you change settings. You can do a manual start and use them immediately. Spray heads are typically underground and will rise during use. This one (in the video) is a mister head – there are a variety of different heads – such as 180, 90, 360 degree heads and also heads that oscillate back and forth.
