This is before the meter though, and I don't think my poco will allow it.use a small PVC Jbox
Local supplier doesn't carry it but I'd be interested in trying it out if that's my only option.They do make such a thing as a rigid expansion coupling. I bought one once for 3/4 or 1 inch. Stupid expensive though.
Possibly. The meter can was nailed to the block on the house, and backed out completely.I would leave the rigid. It looks like they screwed it up when they sided the house.
Nothing is fastened because the siding guys removed everything so they could install siding. That would be my guess.For this pipe to move that much, it would have to be frost heaving, not temperature - you could heat the rigid with a torch and it wouldn't expand that much. If it's frost heaving, an expansion fitting might help, but if that heave isn't straight up and down, the fitting might bind. So you might go to all that expense and trouble and it still gets pushed around.
Is it really frost heave? You wonder what you'd find if you exposed the underground a little. I don't see a jacket so I don't think it's a stub around cable, but if that's the case, just securing the conduit might fix the issue. If it's pipe all the way, you might prevent the heaving if you dig around the pipe and put some sand / gravel.
What's going on there, am I missing something or I don't even see mounting screws inside the meter can, and I don't see any strap on the rigid? It's like the meter's set on a pipe stake that also happens to contain the utility service.
I wouldn't be surprised with everything unsecured, it just settled / sank. That could explain the "S" shape curve of the SE too. Yep, I think I just convinced myself, I think it just sank / settled.
Actually, you can see the J-trim from around the base in the picture if you look close.Nothing is fastened because the siding guys removed everything so they could install siding. That would be my guess.
My observation throughout my life leads me to believe the sider's are not only the culprits but also drunkards to boot.Nothing is fastened because the siding guys removed everything so they could install siding. That would be my guess.
Correct, not thermal expansion. But expansion joints are also used on verticals where the ground can settle or heave.RMC doesn't expand enough to warrant an expansion fitting unless it is over 200' IMO. The thermal expansion of PVC is much higher than iron, but it doesn't need an expansion joint either, in that 6' vertical distance. That problem is not caused by expansion.
Okay, I never thought of that. Around here the ground doesn't heave much, probably because of all the rocks in the soil. They say the Ozark Mountain range is the oldest in the US at 1.4 billion years. Unless you live in a river bottom, your soil can be as much rock as it is dirt. When you go to dig a hole, you take a pick, a rock bar, and a small shovel for any dirt you find... I'm retired, but in 25 years I've only seen or installed expansion joints on conduit coming up to service on government jobs where the spec.'s require them. I've had to use lots of them on PVC in parking garages though, to keep if from pulling it apart in winter, and bowing out like spaghetti in the summer.Correct, not thermal expansion.

Some other reasons for expansion joints could be to account t for improper back filling. If the backfill is frozen or not tampered down it could eventually settle and take the conduit with it. Also frost heaves could take the conduit up and down.Okay, I never thought of that. Around here the ground doesn't heave much, probably because of all the rocks in the soil.
