The Butterfly Sprinkler

Cribb Engineering have their Butterfly Sprinklers manufactured in Australia, using stainless steel. Off-the-shelf butterfly sprinklers are unreliable and poorly made and do not meet with the Cribb standards.

  • Constructed from brass
  • One moving component
  • Spins very rapidly, throwing the water in a 360 degree ball of water
  • If installed correctly can use the wind to their advantage and will normally out perform
    and be more effective than impact sprinklers.
  • Able to spread the water at more even volume
  • Installed correctly and at the correct spacing, creates a constant barrier of water.  If affected by the wind, this barrier of water moves as a unit, however, it is constantly being supplied with water so that as soon as there is any relief in the wind, this system immediately reverts to its original performance which is covering all areas at one time.
  • Less expensive
  • Low Maintenance

The Impact Sprinkler

  • Poor performers and unreliable during a bushfire
  • Very ineffective during a fire and seriously hampered by high winds.
  • Constructed from brass
  • Several moving components and springs
  • High maintenance
  • Poor performance
  • Cannot spread water over 360 degrees simultaneously. Therefore, when operating in one direction another area will not be receiving water. When this occurs and under extreme hot conditions, areas such as windows can become vulnerable to radiant heat and hot enough that they are ready to crack. The next time the jet of cold water comes around and hits the hot glass the window may break causing the very fear we all have – broken windows during a bushfire.
  • Attempts fail to create a more consistent coverage by installing two or more together.
  • Impact Sprinklers rely on gravity to bring the flow or spray of water back down to the house or ground when aimed above the roofline or high above the ground to gain distance. This is where wind effected problems occur.
  • Impact sprinklers are greatly affected by wind because as water leaves the main jet it leaves as a single mass, this mass is necessary to enable the water to travel long distances. However, once it is speeding through the atmosphere the mass begins to split up into droplets. These droplets, unfortunately, lack the unity of the original mass, hence the ability to push through the air. Should they be pushing into a head wind the distance the water will travel will be greatly reduced, to a point it will often travel backwards. This in turn reverses the required result and will render the sprinkler completely ineffective.
