Warning
If the pipe you are repairing carries potable water, you may need to use different connections and fittings. Check your local codes to ensure you're using the proper tools and materials.
Shut the Water Off
You don’t want to be bailing water while you are trying to dig. You can always turn the water on if you think you are getting close to the leak. Or, turn the water on once the pipe is exposed to see exactly where the leak is located.
Dig Carefully
Unless you know how deep the pipe is located, you should dig carefully so that you don’t end up hitting the pipe. If you know about how deep it is, you can dig the first bit quickly until you get closer. Otherwise, dig slowly. As you get close to the right depth, switch to a smaller trenching-style shovel for more control.
Plan the Cut
First double-check the location of the leak. It’s important to pinpoint where the leak actually is so that you can decide what fittings you’ll use for the repair. If the leak is at a tee, you may be able to loosen the clamps and remove the barbed tee from the pipe so that only one pipe has to be cut.
Install the Fittings
Put the pipe clamps onto the pipe before inserting the each barbed fitting into the pipe. Insert one end of the fitting into the pipe, pushing it in as far as it will go.
Tighten the Clamps
Slide the hose clamps up so they are positioned over the barbs. Tighten each of the hose clamps with a screwdriver, using the pinch clamp tool if necessary. Make sure the clamps are secure and don’t move around.
