Use the Submatic E-2 emitter for gardens or other closely spaced plants. The Submatic E-4 emitter is best for subsurface applications. For more trouble-free operations, the vibra-clean pressure compensating emitter is recomended. For container or other watering of isolated plants, use the inline emitters in 1/4" tubing with the button emitters on the ends. Another good way to water containers or hanging baskets is with the adjustable emitters that have a flow rate from 0 to 10 gallons per hour. Jets are great for sandy soils or for watering foliage. Foggers are used to control the temperature and create a mini-atmosphere above plants. Mini-sprinklers cover a much greater area - up to 30 feet in diameter. Ultra-jets also cover a greater area. For large tree areas, you may prefer the new low angle mutli pressure sprinklers installed permanetly with PVC pipe or with a quick coupler system.

For gardens generally a 2-foot spacing will cover the area. For isolated plants - grape vines and berries for example - 1 emitter per plant is usually adequate. Trees may take up to 6 emitters per tree depending on their size. Under good soil conditions, 1 emitter line between 2 rows of plants may be adequate. Refer to charts for the maximum length of emitter lines and to calculate the precipitation rates for each emitter.

Calculate in gallons per hour and convert the total amount to gallons per minute by dividing the total gallons per hour by 60.

Then you must divide the areas into sections; keep in mind that some areas need more water than others. So group thoose areas together.

Friction loss through pipe and hose is an important factor. Differences in elevation should also be considered. As a general rule run the mainline hose down the slope, and the emitter laterals across the slope.

If city or domestic water is used, a single hose strainer with an 80-mesh screen may be all you need. Y-strainers with screens are also available for dirty water conditions. Various other type filters are available from Submatic.

If you wish to apply fertilizer or other chemicals through your system, be sure that you provide a backflow prevention device to prevent the water supply from being contaminated.

Starting at the water source, list everything you need to complete your system. We suggest keeping a supply of emitters, couplings and fittings on hand. You will find it an easy matter to add to your system as needed.

A certain sequence should be followed in the installation of a drip or mini-sprinkler irrigation system as depicted in the sketch shown here.

For best results bring the moisture level to field capacity - wet, but not saturated. Operate the system regularly as needed, replacing only the moisture used by the plants. The object is to prevent moisture stress from developing, as opposed to correcting stress.

Before the season begins, check your system carefully for leaks or other malfunctions. Remove and clean filter screens and flush out any sediment that may have collected there while the system was not in use. Consult Submatic for more information.
