What PVC cement should be used for underground use?

You can use any PVC cement. Since it's not plumbing you do not have to use purple primer. You still need primer but you can use clear if you want.

Buried conduit is not considered watertight regardless of material or joining methods.. The wires inside must be rated for wet locations, for example THWN is a wet rated conductor.

This is for a sewage injector pump system that will be going to my septic tank. Wasn't sure if they made pvc cement that was better for underground cold and wet ground conditions...

The cement is a solvent, it melts the pieces and they fuse together.

I understand about the joints fusing together, the temp here is in the high 30s to 40 degrees. I've seen a lot of different cements online, all weather, heavy duty, quick bonding, wet and dry, and regular cement. I didn't want to glue the joints in a cold damp ground and have my joints come loose for some reason, that's why I was asking..

The different PVC glues have more to do with the conditions they are being applied under than anything else. Once set they should all preform the same.

Since it is a plumbing application I would use purple primer. It's no different than clear but the purple color makes it visible to the inspector so they can see that you used primer.

Thanks, maybe I'll use a faster setting cement seeing the joints will be glued outside in colder weather, I'll be sure to use primer too, thanks again....
