What about the idea of creating some sort of inflatable bladder to insert in the conduit like they have to for those plumbing pipe things they use to help blow out drains. Something that doesn’t let the water/air out unless you open the pressure relief valve. Would be reusable and likely conform to anything coming out of the duct.

The only solution is to hopefully get some air to pass and then keep flushing it out with water. Sometimes you have to let the water soak for 2-3 days between blow out cycles. This has been a problem for me in 4-6” duct. Normally 1.25” and smaller it is mostly water.

I think I shoved the crevice tool into the conduit alongside the cables and then taped over it with 2” electrical tape to mostly seal it. This was only about 25 feet of conduit though, and it was water not mud. It was like a geyser at the other end though.

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.

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. -----Original Message----- From: ch...@wbmfg.com Sent: Wednesday, August 19, 2020 4:00 PM To: AnimalFarm Microwave Users Group Subject: Re: [AFMUG] Locating mud filled conduit 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. -----Original Message----- From: Nate Burke Sent: Wednesday, August 19, 2020 3:32 PM To: AnimalFarm Microwave Users Group Subject: Re: [AFMUG] Locating mud filled conduit 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?

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? -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- Carl Peterson PORT NETWORKS 401 E Pratt St, Ste 2553 Baltimore, MD 21202 (410) 637-3707 _____ -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com _____ -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
