Turning it clockwise can also help lower the water pressure on a spray head that is shooting too much water out.
What is the minimum start pressure for a standard sprinkler?If the pressure at a sprinkler head is below a bare minimum of 7 psi, the water won’t be able to push out the sprinkler cap when the heat-sensitive bulb breaks. This is why no design can have less than a 7 psi “starting pressure” for any sprinkler.
Article first time published onHow many sprinkler heads can you put on one line?
At different pressures, the sprinkler head and nozzle will consume different amounts of water. 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). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
How much pressure does a sprinkler head lose?
Based on this information, expect a total pressure drop of about 15 psi (5 + 4 + 3 + 2 + 1) from the utility supply line to one of the sprinkler heads. If the utility is delivering water to your house at a pressure of 60 psi, then expect a pressure of about 45 psi at each head.
