Whats going on when you run the fishtape from the other end.?

If its 6'8 from the end............

You may have had a coupling come loose. and its dead ending somwhere.


PVC or metallic?

I went over to a guys house that ran me some conduit underground
before he poured the concrete ( he was trying to save a buck or two)
and he installed plumbing 90's which rendered the pipe pathway
useless.

According to Scott Townsend :

I have a 3/4" Conduit that seems to be blocked at the end. We can kind of
hear the Fish tape tink at then stopping point, though we don't know where
it is... We don't know how to locate the end of the conduit. We were
thinking if we could see the end, it might help us determine the location.
It is about 6'-8' to the end of the conduit. I've tried looking for Small
Cameras, but nothing that will really fit in the Conduit. Found a bunch of
Borescopes, though they are too expensive.Aside from the suggestions of measuring how much fish tape goes
in the pipe, are you _sure_ it's actually blocked, and not just the
end of the fish tape running into an elbow or something?

Old trick: tie a piece of string to a ball of cotton batting, and
blow it thru.

I use a plastic grocery bag tied to thin nylon line and use a shopvac
to suck it through the pipe.

Using a blower or vacuum is a good way to help diagnose what's going on
with the conduit. Attach the blower/vacuum to one end and see if you
can feel the air moving at the other end. If you don't feel anything,
you have complete blockage.

Just dont put you ear up to the other end if you are blowing unless
you want and earful. lol



Have you tried using a plumber's snake to see if you can work that
through? If you have 90 degree elbows on the 3/4" pipe, save the
effort - the snake won't make such tight turns. I always use sweep
elbows when I'm running buried conduit and 1" is the minimum size
conduit.
