BASE SYSTEM COMPONENTS INCLUDED IN EVERY SYSTEM WE INSTALL:
A device that turns an irrigation system on and off at a desirable time and operates the system for a preset period of time. In essence, it “controls” the system…hence, the
Hunter units offer
The controller is eas-
ily set by turning dials
or pushing buttons,
giving the user the
ability to select such
functions as when wat-
ering will start, how
long each zone will water and what days watering will occur. Adjustments and bypasses can also be made for seasonal changes and inclement weather.
Hunter electronic controllers have the capabilities to meet the needs of today’s sophisticated, water conscious landscape designs. In addition, they can be programmed to apply water in short cycles, preventing run-off in the most steeply sloped areas.
With great features such as three programs with multiple start times, independent day scheduling options, “one touch” manual start and rapid advance, a programmable event day off, robust heavy-duty locking plastic cabinet, and superior surge protection. Pro-C: delivering maximum flexibility for landscapes that require a minimal number of stations.
With its ability to customize to the particular size you need (from 3 to 15 stations), the Pro-C will always be the right choice..
- Connection to the main home water supply
- Rotators - Rotary spray, adjustable arc nozzles installed on selected pop up bodies or shrub risers
- Various valve & component boxes
If you understand this, you will be able to ensure that the projects you're
involved with comply with local codes and keep the drinking water safe.
Unfortunately, backflow and backflow prevention is not well understood.
The main idea is this: water purveyors want to deliver water to your
property, but they don't want it back, and neither do you, after the water
passes onto your property, it can pick up all kinds of contaminants from
dirt to animal feces. If this water is permitted to re-enter the potable
supply, it can be dangerous.
Backflow is best described as a flowing back or reversal of the normal
direction of water from homes and buildings, leading to the possible
contamination of potable water systems. Backfow can occur at points
known as cross-connections. Cross-connections are generally defined
as any physical connection between the piping system from the water
company's service and that of any other pipeline utilizing this water for Febco 850 'Double Check'
human or industrial consumption. Once the water leaves the company's Backflow
service line, the potential for pollution and contamination can create waterthat is not, or cannot be, approved for human consumption.There are two forms of backflow: backsiphonage and backpressure.
Backsiphonage can be caused by supply leaks in the distrbution system or other high withdrawals of water from the system that lowers the water pressure to the point that a vacuum can then draw used water or other contaminats back int the public water suply system through open outlets, like sprinkler heads or hoses that might be submerged.
The other cause of backflow is backpressure, which occurs when a water user's piping system creates a higher pressure than that in the public water system. This can be caused by pumps, thermal expansion or elevated piping. The increase in the system piping pressure will force contaminated water back into the main supply.
The first step, and pershaps the most crucial of all steps prior to installation, is to look up the local codes in your area.
If the building code calls for it, the landscape contractor has both a legal and moral obligation to install backflow preventers and to make sure they are installed correctly.These devices play a key role in keeping our drinking water safe. it is important to understand what these devices do and why they are necessary.
SYSTEM SHUT-OFF VALVE
One of the most important and under rated, pieces of equipment on a sprinkler system is the shut off valve. It is the main valve for the water source to the sprinkler system. It is the valve you use to perform maintenance and go to in emergencies. This valve will turn off teh sprinkler system water without turning off the water to the entire house or building. It is also known as the ' main valve' but most owners identify it as the 'shut off'. Some systems are incorrectly installed with the backflow acting as the shut off this works until there is a problem with the backflow itself. It's also a problem when winterizing and the valves cocks on the backflow have to be left open for freeze expansion. The main shut off
should be separate from the backflow unit.
It is very important to use high quality valves because, it is ea's
tier to shut off and turn on when you need to. Some valves get
stiff or tight and may be difficult to open and or close.
We recommend and use brass ball valves. The brass ball Val
Yves have a lever handle that you turn 90 degrees to open and
close as opposed to gate valves that have a wheel that you
have to keep turning until it stops. Not recommended for this
application are the PVC ball valves they are sealed inside by Brass ball valve with lever in open position
a rubber gasket that breaks down in time and allows leaking
they can not be serviced and need to be replaced. They are more difficult to open and close because of the gasket system.
UNDERGROUND HOSE BIB CONNECTION FOR WINTERIZING SYSTEM
The compressor is attached to the mainline via a HOSE BIB, quick coupler or other type connection, which is located after the backflow device. Compressed air should not be blown through any backflow device.
This underground hose bib connection is located immediately after the backflow on the main sprinkler line but before the first valve on the system.
Air hose adapted to hose bib
ZONE / STATION VALVES
Valves are installed in the main line and are controlled by an electrical device called a
solenoid located on top of the valve. The
solenoid opens an closes the path for water
to pass through the valve. The solenoid is
activated by the controller.
We work with all the major professional brand valves and constantly attempt to choose the most technically superior models. There are numerous different models to choose from, each with different configuration to handle the many different types of installations that vary from application to application.
HEAD BODIES - Pop up Spray and Rotor
Pop-ups do just what the name implies, the sprinkler body is installed below ground and the nozzle is lifted up above ground on a riser when the sprinkler is operating. After the irrigation is complete, the riser and nozzle are pulled by a spring back down into the sprinkler body. Since the body is typically installed below ground, the sprinkler becomes more or less invisible when it is in the “down” position. This has two advantages. The first is that the sprinkler does not detract as much from the appearance of the landscape. The second advantage is that the sprinkler is not as likely to trip someone, or be damaged by yard care equipment such as lawn mowers.
Spray-type sprinklers are the type of sprinkler that spray a fixed water pattern similar to how a shower head works.Spray-type sprinklers are typically used for smaller areas.
Sprinklers fall into one of two types based on the method they use to apply water to the ground; spray-type (sprays) or rotor-type (rotors.)
Rotor-type sprinklers use a rotating stream (or multiple streams) of water to apply the water to the ground. Rotor-type sprinklers are used for larger areas (generally more than 18' in width.)
Adding a Rain sensor is one of the easiest ways to streamline a system. These economical devices simply interrupt the irrigation schedule when they detect adequate rainfall. While it may seem lake a no-brainer, many systems don't include them.They are standard equipment in our custom systems.
The sight of a sprinkler watering the lawn on a rainy day makes neighbors
(and responsible owners) cringe. Some people simply turn their systems off
during the rainy season, but rain sensors are especially helpful
when people are away from home during the transition
times between seasons.
The Hunter Wireless Rain-Clik™ The unique Quick Response™ feature allows the product to shut off immediately when it starts to rain.
Sch 40 PVC Pipe Fittings are high quality fittings. The standard for use on home sprinkler systems using PVC (Poly Vinyl Chloride) pipe. Most residential installations will use a Sch 40 pipe fitting.These size PVC fittings will provide a system that will be trouble-free for years to come.
PVC Pipe comes in a number of varieties, but the two used for landscape irrigation are Schedule 40 and Class 200 psi “ pressure-rated” (or PR200) piping. Both of these PVC types will work well for landscape irrigation systems. Schedule 40 piping has a slightly thicker wall than PR200 in sizes below 6 inches in diameter and can withstand higher pressures. Schedule 40 is somewhat more forgiving if installed in rocky ground. We use Schedule 40 for our main lines (lines under constant pressure leading to valves) and Class 200 on our lateral or zone lines (lines beyond the valves only under pressure while zone is activated).
