The PVC is a good idea.  We would recommend a larger diameter, maybe 2".  Cap one end and cover the other end with a net when he swims in.  Fill the end of the pipe with squid.  It has a strong scent and few Eels will pass that up.  Doing it at night with the lights off and maybe a led or room light would increase your odds as well. 
Good luck,
