I have some lengths of 2" PVC pipe that I am using for routing ethernet cables (e.g. no water). When I have to push a new cable through, it tends to get stuck on the joints in the pipe.
Is there a good way for me to line the interior myself? It's only a few feet of pipe, and it would be most cost effective to replace it with something else vs. hiring a pipe relining company (if they'd even take the job!). But if there's a simple, effective way to line these pipes it would save me some hassle.
