How many sprinkler heads per line

Each zone should include plants with the same watering needs, or an area of the lawn. The resulting number will equal how many zones you need. If, for example, each sprinkler head will require a flow rate of 1. If your system can only handle If your sprinklers have been consistently weak, projecting water a shorter distance than they are supposed to according to manufacturer information, you may have too many heads on a single zone.

Because a zone runs all the sprinkler heads on it at one time, putting too many on one zone lowers the water pressure for each sprinkler head. If you notice poor performance, reduce the number of heads on the affected zone. Avoid combining sprinkler heads with different flow rates, meaning they use varying amounts of water in the same time, or heads at different elevation levels. Sarah Moore has been a writer, editor and blogger since She holds a master's degree in journalism. Calculating Zones Each zone should include plants with the same watering needs, or an area of the lawn.

The resulting number will equal how many zones you need. By connecting a "Y" shaped hose connector to your hose bib , also called a faucet, you 'll also be able to use the bib for hooking up a sprinkler for the kids without disturbing your sprinkler system.

In the case of the extended coverage heads the square footage can range between square feet per sprinkler head. The most important application when using extended coverage heads is based on the recent testing using the EC sprinklers.

Dig a trench from the new valve to the locations for the new sprinkler heads. The trenches should be 2 to 3 inches below the average depth of frozen ground in the area, or a minimum of 6 inches deep. Cut into the PVC pipe wherever a sprinkler head will be used and install a "T" fitting and a threaded sprinkler riser. Basic Depth Requirements In most areas, burying the pipes 8 to 12 inches below the surface is adequate.

This measurement is from the top of the pipe to the surface of the soil, which means your trenches must be slightly deeper to accommodate the pipes. Plan the System. Access the Water Line. To determine the correct sprinkler pump size , you'll first need to figure out how many sprinkler heads you have along with their GPM gallons-per-minute and PSI pounds-per-square-inch requirements. The rules vary by system type. Pipe-schedule systems and hydraulically calculated systems with a density at or over 0.

Hydraulically calculated systems with less density have the standard foot 4. Rectangular Areas For less easily divided dimensions, place a sprinkler head in the corners and work out the fewest number of heads for each long side based on how far the spray heads or rotors throw. Put a sprinkler head in the middle of the lawn if the area is wider than the sprinkler heads can throw. If you run the sprinkler three times a week during a day billing cycle, you will add about 36, gallons of water to your usage.

Sprinkler Valve Box Manifold. The manifold distributes water to your valves, which are all individually connected. Pump Control Valve. Therefore, the higher the pressure, the greater the flow of the water.

With that said, the best water pressure for a sprinkler system to operate is between 30 and 50 PSI, which will result in even spray-patterns and water efficiency. To increase the pressure, detach a few sprinklers from each zone and close the pipes. Then, install a booster pump on the main water line. Measure the Water Pressure Water pressure is the measure of the force that gets the water through the plumbing system. To measure the water pressure in your house by yourself, follow the steps below: Hook up a pressure gauge on the faucet nearest the water meter.

Ensure that there are no open taps and faucets in the house. Turn on the faucet and read the pressure on the gauge, which is measured in pounds per square inch PSI.

Measure the Water Flow The water flow rate is the amount of water a system distributes over a specific period of time. Get a 5-gallon bucket.
