Since our irrigation heads were installed the evolution continues around the putting green. With time, you have settling of irrigation heads, topdressing and other debris collects around heads and over the years you have a sprinkler head that may look like this one on #14 South.
This past fall we saw a demo of a tool called the Level Lift. I took this description from their web site, The LeveLift is a revolutionary new system that will effortlessly lift and level sprinkler heads that are too low and out-of-level. The key to its amazing performance is the ingenious utilization of the stored energy that resides in your pressurized irrigation system to do the dirty work of pulling the heads. Let the LeveLift do the work Developed by a former golf course superintendent, the LeveLift is a marvel of practical engineering. It utilizes the water pressure that exists at the sprinkler head to develop hydraulic pressure in the system's actuator assembly. When the head is pressurized, the actuator will quickly and easily pull the sprinkler bucket up and into a perfect ground level position.
So we purchased one. We took it out today and in 10 minutes time we now have a sprinkler head that looks like this.
Now the sprinkler head should once again operate properly. By being sunk down in the ground the head did not raise to it's proper height and it probably did not operate like it was supposed to. This new tool should allow us to quickly and easily fix several heads in a day.
