Pulling conduits with vacuum [RE-wrenches]

[Dana Orzel]

Hey there Phil - There is non explosive PVC glue that supposedly is not
harmful to your brain cells too! I think it is called "Gorilla Glue for
PVC". I have not used it, but have heard of it and that it is a bit more
expensive than reg. PVC Glue.
