How to Bury a Comcast Cable
When you need to bury a Comcast cable line, there are a few steps you should take to make sure the line is buried safely and securely, protected from future damage. Depending on the length of cable, you can dig a narrow trench with hand tools, or use power equipment for big jobs. Either way, the basic steps are the same.
Things You'll Need
- Comcast cable
- Measuring tape
- PVC pipe
- Powered trench digger or garden tiller
- Grass seed
Contact the power company and ask for a technician to mark the location of any underground electrical cables before you begin this project.
Measure the distance of the cable line to be buried.
Buy 1-inch diameter PVC pipe to extend the length of the cable line to be buried. You can buy pipe in sections and piece it together later using connectors. Piping and connectors are available at large hardware stores.
Dig the trench in as straight a line as possible, using a hand shovel for short distances or a powered trench digger for big jobs. Trench diggers can be rented for a day or in some cases by the hour from power equipment rental centers. A garden tiller with the two outer tines removed will also work if trench depth is not a major issue.
Make a trench at least 4 inches wide and 8-12 inches deep for the length of the cable to be buried.
Thread the cable through the PVC pipe and lay the pipe in the trench, adding sections of pipe as necessary with snap-on PVC connectors. The PVC pipe protects the cable, preventing rot and moisture and preventing accidental damage from gardening tools.
Cover the trench with dirt, stamp it down and spread grass seed, if desired.
Tips & Warnings
- If you live in a region with particularly harsh winters, consider burying the cable to a depth greater than 12 inches to get it below the frost line.
- Do not attempt to dig a cable line until you have determined that no other utility cables lie in your path.
