Have you ever wondered what all the components of your irrigation system are called?
Just what is an irrigation backflow preventer, anyway? And what does a rain sensor do? Well, here is an irrigation terminology primer to keep you “in the know”:
Pipe
Used to move water from one location to another. There are a number of different sizes and types of pipe: Schedule 40, Class 200, Swing Pipe, & Polybutelene Pipe.
PVC Solvent Cement, Primer, & Teflon Tape
Used to join pipe and fittings together.
Water Proof Connectors
Used to join wire together for a watertight connection.
Sprinkler Heads
Used to displace the water under pressure. Available in pop-up and fixed models as well as moving and stationary. There are a variety of types to choose from based on the size and conditions of the area to be watered. The two most common types are rotor style heads (moving) and mister, or spray, heads (stationary).
Fittings
Used to: join pipe, change the direction of pipe, & allow attachments to pipe (e.g.: sprinkler heads).
Electric Valves
Used in conjunction with the electronic timer to turn on and off water to various zones.
Valve Boxes
Used to house electric valves, backflow preventers, and PRVs to enable
underground access and location.
Timer
The “brains” of the system. The user programs start times, duration, etc. into the timer and it operates the electric valves based on the program.
Rain Sensor
This device monitors rain and suspends the timer’s operation of the electric valves if enough rain has fallen.
Irrigation Backflow Preventer
The irrigation backflow preventer is an important device which protects drinking water from contaminated water in the sprinkler system by only allowing water to flow into the system. Its installation is mandated by the applicable municipal jurisdiction. Learn more about Backflow Prevention here.
Pressure Reduction Valve (PRV)
Used to reduce the water pressure supplying a sprinkler system when it exceeds manufacturer’s specifications.
So, now you know, and you can “talk the talk”. At University Sprinkler Systems, we LOVE talking irrigation. Give us a call today at 604-421-4555. After all, it is probably time for your yearly irrigation backflow preventer inspection, no? All municipalities in Metro Vancouver have a law that all backflow preventers must be tested yearly.
