I'm running some feeders between the house and new workshop. I buried the UG PVC conduit when we were finishing earthwork. I now need to make the connections up and into each building.
Buildings in this part of Texas are all slab on grade and our soils expand and shrink with the annual changes in moisture levels. Theoretically the conduit would move somewhat with the building, but there may still be a differential shifting.
I've seen these slip couplings at Lowes . This sounds like it would take care of any shifting issues. The problem I have is that I have never seen an actual installation where these were used. Not in any of the reading I've done, nor in any local installation I've seen. Also seems like they would introduce a potential leak point. They have double o-ring seals, but those will eventually dry out.
Just wondering if anyone's every seen these used or has a recommendation.
