Plumbing question

[Brass Cannon 25,448]

I have never been to handy and recently had an issue with my sump pump. The pvc fitting broke from my back up pump and caused water to start getting pushed back out by my more powerful standard pump

Trying to id what the raised portion with the ridges is called. It has a gasket that seals to the check valve on the left. 
 

This is the still functioning main pump but piping is identical.

No expert here...but it may be called a PVC compression coupling...or slip nut joint.  It accepts a PVC spanner wrench.  It pulls the two pipe ends together.  

Use a slip nut joint (with or without a turnbuckle) when you need a flexible, adjustable connection, or when accommodating movement or vibrations is a priority.

As a professional civil engineer in a previous life...you owe me 4 tickets to the next final four of IU men's basketball...or an alternative ok by you...for my excellent consulting by searching Google.

Looking at that configuration, I had to chuckle.  Any cracked pipe in that run would be a challenge for me to fix only if I could not get the darn thing apart.  Guessing that may be the challenge on the other section (not shown) that actually broke.  I like long straight runs that accept cutting outside of the problem and inserting a new section with bell end and I tighten a good bell end with a turnbuckle.  But the above, because of the lack of a straight run, is seriously constraining for my sophomoric fix.  Can you get the pipes apart?  Is the problem that the crack is in the 90 bend?  The ridges on the nut are the clues that it is supposed to turn and at least one side of pipe might be threaded to accept the nut.  If it is glued then it is a more challenging problem.  May have to cut out the problem and the check valve.  Then replace the whole thing with a new check valve and sections of pipe.  My unfinished basement is a great place to see the exposed pipe runs and electric etc.  Love my unfinished basement.  I can swing a wrench and do serious damage.  I had two sanitary vent risers that were black ABS plastic pipe...the cleanout cracked in the wye.  Cut out a long straight stretch and put in a new white one.  PVC has two steps to glue together ends.  ABS has one.  ABS is stronger and can deal with shocks and low temperatures.  I have black ABS pipe runs for my sump pump discharge and suction.   But some studies report minor health risks if found in food.  And there may be some local regulations against it's use.  PVC really is better for not leaking warmth when transmitting warm water.  It may also dampen the transmission of sound.  But the two step process takes longer...    Did you get your nut off?  On second thought...disregard my question./s

Here’s a picture of the whole system. The thing that complicates everything is this is in my sump pit. So very tight. 
 

The part that cracked was the threaded piece that compressed the valve.

A very wise decision.

The coupling right before the slip nut joint is really complicating things for you.  But if all that's broken is the slip nut then really this is just a $3 fix

I think it is just the slip nut. How do I get the new one on if it buy the part is it simple?

Disclaimer:  I am not a plumber and I don't know code in Indiana.  But I'm a DIYer enough that I gutted my three bathrooms and kitchen, did all the work (except electrical) myself.  PVC plumbing is incredibly easy.  

Slip nuts are so easy you'll actually think you're missing something.

Imo your biggest challenge is if your 90° elbow is glued (circled).  If not, you can remove the broken nut, swivel it up, put a new one on, reconnect.  2 minute job.

If you do have to adjust anything and you're good with DIY and your hands, you'll save hundreds of dollars on your own.  Plus gain the knowledge for a future project.  Youtube can walk you right through slip nuts.

I see. This is really about problems you’re having with your man “plumbing.”

it’s ok we understand. But if you really don’t know what the “raised portion with the ridges is called” I don’t know what to tell you…,

I’ll check to see if it’s glued tomorrow. But regardless I can’t find the right size slip nut. 2 1/2 inch or 3 inch depending on how they are measured
