If the tie-in point to your  water meter, service line, or existing outlet is within  50 feet of the valve locations, use a supply line pipe  equal to the size of your largest control valve. c. Indicate water supply locations: spigots, well, water service entrance, etc. b.Dig trenches 5” to 6” deep, putting any sod on one side and any dirt or soil on the other side of the, trench. Use as many straight runs as possible. For example, in the sprinkler system of Figure 53, only four buried laterals would be needed, in positions 2, and 5. In your system piping will run from the service line (source of water) to the first set of valves, then from the first set of valves to the second set, etc., and from the valves to the sprinkler heads. However, large sprinklers are not recommended for irrigation of delicate crops such as lettuce because the large water drops produced by the sprinklers may damage the crop. c. Valve locations are determined largely by their  nearness to your service line and existing outlets. Take one wire from each valve and, connect to a common terminal on the timer. Apply solvent and glue to both pipe and fitting. Examples of sprinkler devices used on irrigation systems. For example, only bubblers should be grouped together. Let’s take an example, if we are designing a fire sprinkler system and we know that we required a design density of 15.0 mm/min over the design area then this is the starting point for our fire sprinkler hydraulic calculation. The system is supplied via 100mm PVC PN6. Then turn on the water. Another, important factor is elevation, because you will lose approximately 1/2 psi per foot of elevation going, up a hill, and gain approximately 1/2 psi per foot of elevation going down a hill. In some cases these pipelines are permanent and are laid on the soil surface or buried below ground. A good clean supply of water, free of suspended sediments, is required to avoid problems of sprinkler nozzle blockage and spoiling the crop by coating it with sediment. The type of valve depends on local plumbing regulations. A step-by-step installation guide with detailed instructions for … The sprinkler design must ensure that the flow does not exceed the system demand as stipulated in Table 6.4.7a. In other cases they are temporary, and can be moved from field to field.
