Conduits for electric wires hold and protect electrical wires. To avoid damage to conduits and wires it is important to install conduits away from sources of heat and water. In event that conduits are damaged it is important to repair them promptly to avoid damage to wiring. Damaged conduits may be a sign of damaged wiring.
There are different types of electric conduits. Match the replacement electric conduit with the existing conduit. Ensure that the conduit is wide enough to hold and rethread all the wires.
Tools: Electric conduit, conduit connectors/fittings, pipe cutter/conduit saw, wrench, pliers and/or screwdriver, threading tool, electric tape, electric fish tape, electric pulling lubricant.
To uninstall conduits for electric Wires
1. Shut off the electricity flow.
2. Disconnect the wires as close to the damage as possible. This will reduce the amount of rethreading wires through the conduit later on.
3. Pull one end of the wires out of the conduit.
Note: In many situations it will be helpful to attach fishing tape to the wires and wrap electrical tape around them before the removal of conduit wires. You will need to separate the fishing tape from wires later on to get rid of conduits that were damaged and to install the new sections of conduit.
4. Unscrew or use pliers to remove conduit supports.
5. If the damaged area is part of a small section of conduit, use a wrench to unscrew the electrical conduit fittings on both ends of the damage.
If there is a large section of conduit, use a pipe cutter or conduit saw to cut out the damaged section of conduit. Cut a couple of inches extra into the undamaged parts of the conduit.
Get rid of conduit pipes that were damaged.
To install the new conduit for electric wires
6. Measure the size of conduit needed to replace the removed conduit.
7. Cut a piece of conduit piping with a pipe cutter or conduit saw according to your measurements.
8. If the wires in the original conduit are accessible, pull them out of the conduit opening.
9. Place the wire through the new conduit. If needed, detach the wires form the electric fishing tape.
10. If you did not push the electric fishing tape through the conduit (as recommended in step 3), push electric fishing tape through the conduit starting where the wires were disconnected.
11. Wrap the uninsulated end of the wires around the electric fishing tape head and wrap electric tape around them.
12. Put electric pulling lubricant on the electric tape that covers the head of the electric fishing tape.

13. With a wrench, screw electric conduit connectors over your cut piece of conduit and over the existing conduit on both sides. Make sure it is tight.
14. Screw the conduit supports back where they were.
15. Pull the wire though the conduit using a threading tool to feed the wires into the conduit and by carefully pulling on the fishing tape on the other end.
16. Reconnect the wires to there original place.
17. Turn the electricity back on.
