Line Vac Pulls "Fish" String Through 120 Feet Of Underground Conduit

A contractor normally used a small electrical vacuum to pull a "fish" string through 4 inch electrical conduit. If there was any delay after the conduit was installed before the string was pulled, then water, wildlife, or debris could enter the conduit. If this happened, they had trouble pulling the string through. They recently encountered such a clog, and when they couldn't clear it with a plumber's snake, they tried a Model 6087 4" (102mm) Aluminum Line Vac to the inlet of the conduit. The Line Vac was able to remove the clog and blow the string through 120 feet of conduit in less than 30 seconds.
