When you are satisfied there are no leaks, turn the valve off. If you do happen to find a leak, unscrew and reattach the bushings and pipes, taking care to screw them together more tightly this time. It’s important to check for leaks before you shovel the soil back in place over the water lines. If you don’t, you could end up needing to dig up the lines again in the future to find a leak. Only backfill the ditches once you’ve walked the ditches and confirmed that there are no leaks. Once you’re certain, use your shovel to scoop the dirt and organic material that you dug out earlier back into the ditches.

Dispose of these materials in the trash or compost bin.
