WaterSavers: A New Conservation Tool

Rose

What does each WaterSaver disk do?
Inserting one into the bottom of EACH adapter stabilizes the original volume and pressure in the irrigation station. It allows just the right amount of water to pass through the disk BEFORE it goes through the nozzle. This helps to reduce nozzle fogging and runoff and leaves you with extra water to negotiate with so in most cases you'll be able to double up stations. 		Which sprinklers can I use them with?
WaterSavers fit easily intothe bottom of the shrub head adapters found on the RISERS throughout your landscape.

Amounts will fluctuate according to changes in pressure and volume

How many WaterSavers will I need?

Count the risers and categorize them into 2 groups. The ones with the 1/4, 1/3 and 1/2 nozzle spray patterns need a GREEN WaterSaver disk and the ones with the 3/4 and full nozzle spray pattern need a BLACK WaterSaver disk.

Putting WaterSavers in Toro Adapters

Disassemble nozzle from adapter and remove the filter that may already be there. Reassemble nozzle and adapter. Insert WaterSaver into bottom of adapter. Put our filter or the original one into the riser.

What are the conservation benefits?

On the average, each WaterSaver disk saves 1/4 gallon of water per minute per sprinkler. It completely maintains the original nozzle spray pattern so you don't have to compromise on coverage.

WaterSavers have been used and tested at residences in Contra Costa since 1987. In 1988, studies from a local water district showed that these residences used 32% less water than they did in 1987 because they followed our Outdoor Water Management Program, used WaterSavers and conserved water indoors. In 1989, studies showed that residences from the original group had saved more water from 1988-89 than from 1987-88. The yards set up with our WaterSavers saved 12% more water than those that weren't.

WaterSavers into RainBird Adapters

Disassemble nozzle from adapter and remove the existing Rain Bird filter.With scissors, cut off the top half of the filter and discard the bottom half. Reassemble nozzle,top of filter and adapter. Insert WaterSaver into bottom of adapter. Place our filter in the riser.

Bucket

  • Twist and remove shrub adapter from the riser
  • Insert WaterSaver into bottom of shrub adapter
  • Insert filter into riser
  • Reassemble shrub adapter back to riser

FOR BEST RESULTS...

Clean the nozzle of all debris such as bugs and rocks.
Use the filter to keep the WaterSaver disk clean.
Completely open up the flow adjustment screw on the nozzle before inserting the WaterSaver disk into the adapter. Then turn on the water and adjust the screw down if necessary.
  • Follow the illustration above to set up for your bucket test.
  • Use the enclosed green WaterSaver disk with a nozzle that has a 1/2 spray pattern for test,
  • Insert WaterSaver into bottom of adapter and screw adapter back into riser (Fig. B).
  • Turn the water on. hold the bucket under the adapter for 1 minute, then remove. Turn water off and pour water from the bucket into a measuring container.
  • Remove WaterSaver and repeat procedure.
  • Compare the two measuring containers and record your savings.

PCD

PCD

Pressure Compensation Device. A plastic or rubber cone that is attached to the bottom of a nozzle. It has the same function as a WaterSaver. PCD's are inserted into pop-ups and shrub adapters.

WaterSavers

WaterSaver

A plastic disk that is inserted into the bottom of a shrub adapter. Its function is to stablilize water pressure, reduce fogging and reduce water runoff. WaterSavers come in green to accommodate 1/4, 1/3, 1/2 spray patterns, and black to accommodate 3/4 and full spray patterns.
