喷头结构很简单, 1/2"的塑料管(PVC riser)上拧了个喷头,
理论上只要把喷头换成盖子既可.
但实际上密封很差, 很多水从螺纹的缝里漏出来.
怎么办呢? | l*t

- Remove the soil around the sprinkler head till you see the bottom
- Un-screw it to take it out. Keep the opening off soil/dirt
- Go to HD or Lowes to buy a properly size plug to screw it on
or You can buy a different sprinkler head to put it on | d***n
