I have my first ever tank plumbed and set up for testing. I have a small leak at the main drain. What are my best options to correct this?

It looks like you either forgot to use PVC glue or, you didnt get a good glue joint.

If you forgot the glue, remove, dry, prime and glue. Dont forget to give a 1/4 turn once pushed in all the way.

If you remembered the glue and it still leaks, you can dry it so theres no water coming out, and put a bead of pvc glue around the joint where the pipe meets the bulkhead. (Where its leaking from)
The glue will melt the pieces together. Ive done this a few times on water treatment loops.

Yea I did use glue but may not have done the quarter turn. I’ll try glue where the pipe meets the bulkhead. Thanks!!

No problem.
Ive had my fair share of pvc leaks until my coworker (jouneyman plumber) taught me that neat little trick of giving a little twist before the glue sets up.
Ensures a complete seal.

The exterior gluing was my own discovery LOL.
 
Exterior glue actually appears to have made this worse. Any reason I could try some WaterWeld?
 
I'll have to dig around for it but there is a video out there of someone fixing an issue like this by using a vacuum and solvent (PVC "Glue").

You tape off the bottom of the pipe and place the vacuum hose on top so its sucking from the bulkhead end. Then apply solvent around the area where the pipe meets the bulkhead. The theory is the vacuum will suck the solvent in-between the bulkhead and pipe where there are gaps and bond them they way they should have been originally.
 
It’s not glue, it’s cement. Bulkheads are much softer than reg schedule 40 pvc. Because of that after you prime the bulkhead you must let it dry at much longer than the few minutes the schedule 40 needs.
 
Yes I did notice that when applying the cement. As I was applying the cement I had black streaks as it was immediately ‘eating’/melting the bulkhead.
 
I would cut the pipe in a place there is room for a coupling and put new bulk head in. You dont want problems down the road. Only reason I don’t like unions on drains is that it has a smaller inside diameter which is going to restrict flow.

Hold the pipe in place while making the connection with the bulkhead. For whatever reason the bulkheads like to push the pipe out until cement is dry.
 
This was literally the first ever plumbing connection I made so lesson learned.
