What is the 3 times rule for sprinklers?
The “three times rule” found in NFPA 13 states that “sprinklers shall be positioned away from obstructions a minimum distance of three times the maximum dimension of the obstruction. For example, if a ceiling fan hub measures 4 inches by 7 inches, the sprinkler must be positioned at least 21 inches away from the hub. The “three times rule” found in NFPA 13 states that “sprinklers shall be positioned away from obstructions a minimum distance of three times the maximum dimension of the obstruction. For example, if a ceiling fan hub measures 4 inches by 7 inches, the sprinkler must be positioned at least 21 inches away from the hub.For sidewall sprinklers, the rule applies if the obstruction is within 18 inches below the sprinkler deflector. It says that the maximum distance from the sprinkler deflector to the obstruction is the smaller of four times the largest dimension of the obstruction or 36 inches.Light Hazard (10-15 ft). Excluding heads in combustible concealed spaces, all sprinklers in this category have 15 feet (4. Ordinary Hazard (15 ft). All sprinklers in these environments have a 15-foot (4.A common rule that is followed for obstructions within 18 inches of the sprinkler deflector is the “three times rule”.

How long should an oscillating sprinkler run?
Description: These sprinklers rotate to deliver a stream of water, covering the area in a sweeping motion. Water Delivery Rate: Approximately 1 inch per hour. Approximate Running Time: For 1 inch of water per week, run these sprinklers for about 1 hour weekly, split into two 30-minute sessions in early mornings. 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.Each system delivers water at a different rate, but this is typically about 30 to 45 minutes per zone.
