Generally, spray heads use about 0.75 gpm for ¼-circle, 1.5 gpm for ½ circle, and 3.0 gpm for full-circle heads. "Rotor" style heads use 2 to 5 gpm each, for most residential applications.
Rain Bird High Performance Sprinklers are built rugged to withstand the harsh conditions in agricultural applications. With flow rates ranging from 0.28 to 6.82 gpm (62 to 1,549 l/h), these sprinklers deliver precise, uniform and unrivaled water distribution.
Rain Bird lawn spray heads usually emit over 1 inch per hour.
The average usage of water in a residential sprinkler system is between 12 – 30 gallons per minute depending on the type and size of the sprinkler head.
The average system uses approximately 15-16 gallons per minute, per station. Here is an easy formula to help you calculate the approximate amount of water you are using each month.
To determine how long you need to water to get one inch, place a plastic container in your yard and set a timer. On average, it will take 30 minutes to get a half inch of water. So, 20 minutes, three times per week will give a lawn about an inch of water. This formula works best with healthy, well-cultivated soil.
Watering with a typical sprinkler using a standard 5/8" garden hose for one hour uses about 1,020 gallons of water; if you water three times per week, that's about 12,240 gallons per month.
Normally each sprinkler head can deliver anywhere from I to 6 gallons per minute. A typical residential water meter can deliver 30 gallons per minute. With this in mind; 5 sprinkler heads can use 30 gal/min.
The answer is that it usually takes up to 30 minutes to get a half inch of water. Watering 3 times per week equals to an inch of water on a lawn.
For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM).
Therefore, to apply one inch of water, you need to run your sprinklers for 76 minutes. However, running the sprinklers one time for 76 minutes might push the waterway past the root zone of 4 inches. Loam soils take up between ¼ and 2 inches per hour.
For conventional sprayheads, precipitation rates typically range from 1.3 inches to 2 inches per hour. For gear drive rotors, precipitation rates typically range from 0.4 inch to 1 inch per hour. For rotary nozzles, precipitation rates typically range from 0.4 inch to 0.6 inch per hour.
You can operate 2 or 3 sprinklers at one time with 'Y's and extra hoses, depending on your water pressure. To run more than one sprinkler off the same faucet, attach a 'Y' to your faucet and run a hose to each sprinkler.
As for its components taken separately, good quality heads will last you anywhere between 10 to 15 years, while inexpensive ones will only be good for 2 or 3 years. Nozzles should usually be replaced after two years, depending on water quality and climate.
Rain Bird's High Flow Inline Pressure Regulator family provides a wide flow range coverage (0.5-70 gpm) while delivering reliable pre-set regulation to protect and maximize the performance of most irrigation installations. Available in 40 and 50 psi versions.
One inch of water or rain is equivalent to 623 gallons per 1,000 square feet.
Sprinklers generally cover up wider ground and spread out water at a slow yet steady pace, which makes all the soil moisturized evenly and soaked underground. A watering hose takes time to cover space and can clutter the soil if there's too much water.
If your sprinkler output is 1½ inches per week, your sprinklers should run for only ⅓ hour or 20 minutes that week (½ divided by 1½). On a twice-weekly watering schedule, run your sprinklers 10 minutes each time.
Fixed spray heads apply 1.5 to 2 inches of water per hour in a fan-shaped spray. Rotors apply about 0.5 inches of water per hour in a single, rotating stream of water. Rotary nozzles apply approximately 0.4-0.6 inches per hour in multiple, rotating streams of water.
To calculate the amount of water you use, multiply the width times the length of your yard in feet to get the number of square feet of area. Then multiply that figure by 0.623 to come up with the number of gallons used (or use our calculator below).
The water industry estimates that an average person uses 3,000 gallons of water monthly, so a family of 4 would use 12,000 gallons for bathing, cooking, washing, recreation and watering.
