Running wire

1. When installing electric conduit all the pipes are cut and glued before the wire is run through the conduit.  

2. After the conduit installation is finished, a string is blown through the piping leaving exposed tails at both ends.

3. The desired wire is then attached to the string and pulled through the conduit with the string.

4. Pull the string all the way through until the wire attached to it is pulled out the other end.

5. Thats it, untie the string from the wire and your done.

Air Compressor for blowing string through piping

I tie a small piece of foam to the end to my string to create a tighter seal in the pipe.  With a tighter seal more air pushes the string down the tube instead of air just being blown through the tube.

With the string in the pipe blow it through with an air compressor

String with foam blown through and hanging out the other end

I pulled a single 14g wire through with the string.  This way when pulling a heavy wire or multiple wires through the lightweight string wont snap and you can pull as hard as you need on the 14g wire.

Pulling a bunch of six 14g wires through

Pulling on the opposite end

Out comes the bunch of wires
