The water source for irrigation systems is normally the water meter. From the meter, water flows through a Pressure vacuum breaker, or PVB.  A PVB

prevents contaminated water from entering back into the clean house water.

This safety device is usually located along the narrow sides of a house, behind

a shrub or fence.  After flowing out of the PVB, water enters into the irrigation system mainline.  

        There is not enough water to cover a yard all at once, so it must be done

one section at a time.  These sections are also know as zones.  Each zone is

operated by a electric valve. Valves run for a designated amount of time, then cycle to the next.  Zone cycling is controlled by a automatic timer.

        Timers are usually installed in garages, with irrigation wiring going to them from all the valves in the yard.  Electricity for the sysem is low voltage, 24 volts.  Timers have battery backup to keep memory in the event of a power outage, and are installed with a rain sensor.  Rain sensors prevent watering during and after it has rained.

        Three types of sprinkler heads are used for irrigation.  The first type, rotors, are used for large grass areas.  The second type is a riser, used for

irrigation of shrubs and flowerbeds.  The third type of spray head is a pop-up.  These come in a assortment of different sizes, 4, 6, and 12 inch.  They are

used for both smaller grass areas and flowerbeds.  

            

                                                           Parts

        Green Oasis uses two manufactures for irrigation components, Rainbird and Hunter.  Instead of using one company exclusively, we take the best of

what both these two leading companies have to offer.  All components are commercial grade, and the best series level from both are used.  

       

                                                     Installation 

       Our company uses a unique machine that digs a very narrow and deep

ditch for grass.  Once the piping is installed, dirt is packed back into the ditch and reseamed by rakes.  This seam is gone in several weeks, whereas hand

digging sod leaves a scar for some time.  We refer to this method as a surgical

installation, not nearly as intrusive as hand digging can be. 

         PVBs are isolated from view, with a isolation valve located in between a water source for freeze protection.  Wiring in the garage is installed behind the wall, not stapled to the wall like many companies do, giving a clean appearence.  Sprinkler heads are neatly placed so that they will not be damaged or spray on objects that do not require water.     

         After installation is complete, the customer's yard is thoroughly cleaned.

The sprinkler system is then adjusted and set for automatic operation. 

We will then return in several weeks for the final walk through, adjusting spray heads one more time and familiarizing the owner with their system.

 

                                                      Warranty    

         Each sprinkler system comes with a written three year warranty that

covers parts and labor.  Not only is three years hard to beat, any customer

can extend thier warranty for referring us to another customer.  A referral from

a past installation client will add one more year on to thier exsisting warranty.

No other competitor offers this incentive!

 

                                                       Payment     

          Two weeks after the break-in period, payment is due when we return

for the final walk through and present the invoice. Green Oasis accepts cash,

checks, and credit cards.  We also offer financing through John Deere Credit,

or possibly we can arrange installments to help ease financial constraints.
