Tricky angle trick?

I'm laying pipe in a trench to feed solar panels. As you can see from the pictures the angle on the 22° elbow is just slightly off so the pipe on the right does not seat fully in the elbow. If everything else is rigid already, is there a way to get this connection right so it will not leak?

You can cut back 12 inches. Put in a coupling to connect a short piece of pipe. Then on that short piece of pipe, cut one end of its length such that is matches the angle of the elbow. It will be on a diagonal and should slide right into it to seat. The end will be square to fit into the coupling that was added to join the pieces together.

Two 45-degree elbows put together in an "S" shape can be rotated to match the offset and have proper depth of fitting for a good glue joint. That fitting looks like a DWV with its very shallow glue area.
Ask any leak detection/repair company and they will tell you that most underground leaks in the plumbing happen at a 45. Burying that tiny fitting is just asking for a leak.

Those fittings look like DWV fittings and shouldn't be used for pressurized runs.
The DWV fitting depth is much more shallow than a schedule 40 fitting.
 
Thank you all for your replies -- one thing I learned is that while all my pipe is good (Sched. 40, pressure rated), all my fittings are DWV and not pressure rated. That includes a whole bunch of 90s, 45, 22s and couplings all along the route. Is strong recommendation that I redo the whole run with proper fittings for pressure?

I noticed the same thing and suggest removing any DWM fittings to avoid having to dig things up later. You will thank yourself for doing the work now while the trench is open.
