1 conductor is broken between the JB and the pump. This conduit 'LBs' out of the building to an EY fitting,then to the pump Manhole. There is an inline fitting,similar to an 'EY' there (just before entering the JB for the pump). Not a problem.
What is the best way to get all the packing and sealant out of these fittings? And re-loading the 'inline' fitting? So as to facilitate a quick easy pull.
This is on the load side of all controls,Pump feed only.
There is no easy way. If the sealant was installed properly there is a real good chance you will damage the conductors in the conduit as you chip out the sealant. I would first try to chip it out and see how much a PITA that is. If that proves to be a pain I would look into listed,approved unions and a new fitting and just cut the conduit pull out the conductors, fix the conduit ,pull in new conductors, and reseal.
Do you have the tools to thread pipe? If you can get in there you could cut it off and rethread the pipe I suppose. Easier than eating up the driveway to run new pipe. If you were lucky there would be a coupling below the sealoff.
You can do that if you can find NM that's rated for use in a Hazardous environment.
Besides, temporary fixes tend to never get done right. As soon as things are jerry-rigged to run, the urgency to getting the thing fixed correctly just sort of goes away. Just look at some of the 'temporary' horror stories on this board.
Those sealing fittings were not designed to have the stuff chipped out of them, so it's a royal PITA to do that. I think you're stuck replacing the fitting unless you want to spend a lot of grunt work chipping and vacuuming.
Maybe you'll get lucky and whoever sealed them first packed the pipe with DuxSeal to keep the compound from running too far into the pipe. I see that around here all the time and it sure makes it easier to break it out.
Just in case you haven't dealt with this stuff before, here are the main ways Mr.Murphy can complicate things:
1) First, it's not unheard of fo the seals to have never been sealed. Oops! In that case, thank heaven, and simply pull out the bad wires. Then pack the seals properly.
2) Often the fiber dam fails, resulting in the mortar-like sealant running down into the pipe, and setting up in some low spot. Shovel time! You get to dig up the pipe, usually to the first sweep.
3) Other times the rigid pipe will corrode, with flakes of rust or collapsed pipe making a new pull impossible. A related problerm - which might be the cause of your bad wire - is when compacting and paving operations break (or crush) the pipe.
4) Often, there is not enough room between pipes for you to cut or thread the old pipe in place. Again, in that case, you're best served by digging down to the sweep, and working down there.
When you do finally getyour new wires in, do yourself a favor, and pull in a few extras; this will -maybe- save the day in the event another wire goes bad.
