Simple, easy to use and effective. (I’ve found that many pressure compensating emitters are not a whole lot more “pressure compensating” than standard emitters are. So you may have a mixture. Typically for a sprinkler this specification will list an inlet pressure as pounds per square inch (PSI) and then give a watering radius (feet) and flow rate in gallons per minute (GPM) that will occur at that pressure. Placing bubblers on the same valve zone with rotors or drip irrigation seldom works out well. Is your water pressure less than 40 PSI static? If you are working through the Sprinkler Design Tutorial, enter the sprinkler head operating pressure (or the drip emitter pressure if no sprinklers) on the “Sprinkler Heads” line of the Pressure Loss Table.

Spray heads are less expensive to buy, but they require more pipe, trenches and valves to install. You will need to obtain these specifications for each of the sprinklers you intend to use. I personally haven’t noticed any significant difference in performance between most brass and plastic nozzles in well-designed, sprinkler systems, although brass nozzles will no doubt last longer. Plus this tutorial has been around since 1997 and successfully used by thousands of people. Rain Bird 32SA/4PKS will provide you greater coverage uniformity.

Covering many different lawn care topics relating to most aspects of lawn care practices for St Augustine grass lawns. They are most often used to water smaller areas where sprinklers would overspray water out of the area, although there are other specialty uses for them.

Pop-up sprinklers often don’t cost any more than shrub sprinklers when you include the cost of the riser (the upright pipe the sprinkler is mounted on). These are often called rotary nozzles or rotator nozzles. Most of my commercial clients ask me to use at least a 6″ height, even for lawns. Typically you install one fixed flow bubbler at each shrub or if they are very small shrubs (not more than 18″ – 24″ diameter full grown) you might install 1 non-adjustable bubbler between two shrubs to water both of them. If you get 4 industry pros together you will get 4 different opinions of products, each a heartfelt honest opinion. The gallon of spray should cover 1,000 square feet. OK, enough fun for the geeks.). Here’s a rule of thumb, “The water pressure at the rotor head in (PSI) must exceed the distance (feet) between the heads.” (Known as Stryker’s Rule, admittedly that’s a little ego stroking on my part, but I did create the rule!) Everyday life can be hard on an in-ground sprinkler. Most bubblers are designed so that the water gently “bubbles” out of them, the reason being to avoid erosion caused by a strong stream of water. St. Augustine grass is a great choice for high traffic lawns. Sometimes you need to use sprinklers that require high pressure such as rotors, with sprinklers that use low pressure on the same irrigation system. For an emitter the product specification tables would include only operating pressures (PSI) and a flow rate in gallons per hour (GPH) for each of those pressures. Plus, they offer a high level of customization. This is a bit difficult to understand but I will try to explain. By using this tutorial you agree to be bound by the conditions and limitations listed on the Terms of Use page.

In practice if I am watering a long planter strip 3′ wide with shrubs in it I will install flood bubblers 3′ to 4′ apart down the length of the planter. Rotary/rotator nozzles are more efficient than traditional spray heads because they produce less “mist” that evaporates before it reaches the ground. Turn trimmer's handle clockwise 360 degrees.

Place the sprinklers for the groundcover about 12″ away from the groundcover, in the lawn area, and aim them back at the groundcover. You may have noticed I used the term “operating pressure” here rather than “pressure loss” as previously used for other irrigation equipment like valves and backflow preventers. Important! Replacing a 6′ radius spray head with a 12′ radius rotator is NOT going to save any water! The second is determining how to space the heads where the different types meet each other. … The conventional wisdom is that metal is more durable than plastic, and therefore is better. for Overgrown Sprinklers & Clean Appearance Adjustment Replacement & Raising Drill Attachment 3.9 out of 5 stars 24 Two major advantages of pop-up sprinklers are safety and appearance. Keep in mind that foliage will block the spray from a stream bubbler so you may need to trim the plants to keep them out of the bubbler’s spray trajectory. We don’t want to blow the sprinkler apart with high pressure– and rotors can cause mist too under extreme pressures. Bubblers flow at higher rates, often measured in gallons per minute rather than hour, and the intent of a bubbler is to flood the ground surface with water. Welcome to Saint Augustine Lawn Care.
