Is it normal for the duct to be full of mud? That seems ungood.
I’m also assuming the fiber in that duct is carrying traffic and
it would be very bad to break it and then not be able to replace it.

You still need a way to get air in the duct. Either this:
https://www.gmptools.com/innerduct-pressurization-test-kit/ or
this https://www.gmptools.com/line-blowing/ to attach to the
compressor. Neither tool is very expensive (relative to the
stupid price of most things fiber)

Put the real cable in the one side and block the other port
or use it for water. Hum… water going backwards through the
compressor isn’t a great idea. And pushing air back the
water supply isn’t great. OK, fill it with water and block
the other port. Add air and wait. Once you have half decent
airflow change to water.

You might get away with sealing it up really good where
the fiber exits and then making a hole in the side of the
duct small enough for the tip of an air blower. Not sure
how much air you will get this way but easy to try. Use
mastic and then tape to seal it. You might be able to
couple a pressure washer to it too.

I have a clamp thing that clamps over the duct and cable
and seals it all
up. It has an air port coming in from the side. And I
use a 375 CFM 150
psi compressor.
I am guessing you could slip a copper tube down the duct
and tape the crap
out of everything with black vinyl tape. Just use as
much air as you can
get. Be sure to inject as much water as you can inject
first.

How do you seal it up with the existing fiber in there to
be able to
blow it? How much PSI do you use? Will a portable air
compressor be
enough? Other end of the conduit is in a building, so I
can only blow
the mud 1 way :)

Use compressed air to blow water through it. Once

Subject: [AFMUG] Locating mud filled conduit
Anybody have secrets for locating mud filled conduit?
Trying to locate
a 1" poly with a non-toneable fiber installed in it.
No trace wire
installed. Conduit is full of Mud, and at the bottom
of a handhole that
is also filled with Mud. Conduit goes from handhole
under a parking
lot, so digging to find it isn't an option either. We
were not involved
in the installation of this conduit, but it is now
our problem.
We got a flat steel fish tape pushed in just far
enough to finish the
current locate request, but it's not going any
farther. At some point
in the future I'm probably going to get a locate
request further down
the conduit path. What super-secret method do you
guys that live and
breath underground work have for dealing with this?
