But you can create two different valve zones and use different sprinklers in each. Effective prevention includes facilitating conditions that hinder fungal infection and minimizing/eliminating conditions that fuel the same. To determine the flow you are using for your design, you can measure the flow by using a 1 gallon bucket and seeing how long it takes the bubbler to fill it. Insert the trowel's spade vertically into the ground to cut through the sod. ft.

See the previous pages of the Sprinkler System Design Tutorial if you don’t know what static water pressure or design pressure means. Can’t find a performance chart or specification for the sprinkler or emitter? For spacings over 20′ it is typical to use rotors rather than spray heads.

However they are great for watering a group of plants provided the plants are located in the immediate vicinity of where the stream lands. a. That means you will probably need around 45 PSI minimum to operate the system since pressure will be lost in the pipes and valves as the water flows to the sprinklers. The best soil for St. Augustine grass is one that is well-drained (like sandy soil) with pH ranges from 5.0 to 8.5. I like to aim for at least 5 PSI higher than the minimum, so for that 35′ spacing I would aim for 40 PSI. (When you adjust the radius using the adjustment screw on a spray head, you are actually reducing the pressure at the nozzle by means of a small valve inside the nozzle.

Terms of Use    Then it will proceed through the meter into the house supply pipe and on to the irrigation system connection. Note that my experience is that this idea doesn’t work as well with larger plants and/or plants placed further than 24″ away from the stream bubbler. There are rotors available that can be spaced farther apart than 65 feet but I don’t advise using them in most situations, even golf courses are moving away from using them due to problems. (No that spacing is not an error, if the sprinkler radius is 12 feet, then you space the sprinklers 12 feet apart, not 24 feet.
