They do make such a thing as a rigid expansion coupling. I bought one once for 3/4 or 1 inch. Stupid expensive though.
Providing expansion fitting for RMC at meter.
I went on an estimate today and found this:
![Plant Brickwork Brick Clock Gas]()
![Gas Font Motor vehicle Gauge Machine]()
Turns out I can keep the existing feeders for the upgrade. I want to install schedule 80 PVC with an expansion fitting so this doesn't happen again. Can I cut the rmc just above grade, slip an rmc compression fitting on there, and thread a PVC female threaded adapter? From there glue in a cut of PVC to an expansion fitting? Any issues doing this? This would effectively separate any bond the conduit has between the transformer pad and the meter. Would I then need to bond to the can between the rmc and the new meter?
Or if there's a better way to do this which I did not mention, please share.
It's not every day I find services fed underground in RMC.
