I need help fixing an inground sprinkler system. How do you repair an inground sprinkler system?You can fix an inground sprinkler system by digging up the broken sprinkler, cleaning the area around it, and putting it back together. If the valve is broken, you can replace it or buy a new one and install it. You may also need to add more water pressure to the system.

There are a few things that could be causing your problem: -The valve might not be turning off all the way, which would cause the water to keep running. Try turning the water off at the shut-off valve and then back on. If the valve doesn't seem to be the issue, move on to... -The pipes might be leaking. To check for this, turn on the water and see if any of the sprinklers are coming on when they shouldn't be. If they are, then you have a leaky pipe.
