PVC (polyvinyl chloride) pipe is a hard plastic pipe used in both residential and commercial plumbing applications. Through the 1970s and 1980s, PVC pipes began to replace metal pipes as the preferred plumbing pipe of choice for contractors. There may come a time when you have to run electrical wiring through PVC pipe. If you are facing this situation, you will have to make sure the electrical wiring is completely waterproof.

Measure the amount of electrical wiring you will have to waterproof with a tape measure and write this number down. Also count any electrical joints or connections and make a note of that as well.
Purchase silicone sealant and enough heat-shrink tubing to cover any electrical joints you will have to waterproof.
Mix silicone sealant, if needed, according to the instructions on the package. Use a small paint brush to apply a thin layer over all the wire you will have to cover. Allow adequate drying time according to directions on the silicone sealant packaging.
Fit the heat-shrink tubing over all electrical joints.
Plug in the heat gun and melt all the heat-shrink tubing over the joints. Allow time for all the joints to dry completely.
Run your wiring through the PVC pipe for your project.
