what kind of machine or tool can you use to dig channels in dirt for sprinkler systems?
<answer> Flexible pipe. <context> Before adding sprinkler heads, flush water through system to clean out any debris. Tap into the waterline. Attach fitting into the saddle (two types of fittings, your choice) and one into the sprinkler head. Be sure to use a smaller, more flexible piping (Image 1) to go from the main pipe up to the sprinkler head. This type of piping is more manageable and will curve easily. Fill in with some dirt. Level the sprinkler head with level of sod (Image 2).
