PVC return to bulkhead

[Palmer]

How is the union fixed to the threaded adaptor? Since it should be able to be pulled apart I am assuming it is not glued?

The union could be close to the TA (threaded adapter) just with a short nipple (made from pipe) or 20 feet away from the bulkhead in the basement.

The TA threads into the bulkhead (use teflon tape or dope), the nipple is glued into the TA and union (unless using a threaded union where you then would have another TA).

If using true union valves make sure they're mounted the right way (see here).

Thanks Mark I am a complete newb when it comes to this stuff. I didn't realize a union can be taken apart to then allow you to detach without cutting anything.

They are awesome tools to have in plumbing... pricey, but so convenient!

I you havnt bought them already then try to get the un-threaded bulkheads. The threaded ones are prone to cracking.

Thanks for everybody's advice. I did all of the plumbing on the tank yesterday and it came out pretty good! I do have one extremely slow leak where one of the bulkheads meets the threaded adaptor on the outside of the tank. It looks like it is about a drop every couple of minutes. I am not ready to fully set up the tank yet so I am thinking of letting it dry and applying a little silicone to it.

it's okay to use silicone tape or pipe dope, not good practice to place a bead of silicone sealant over a leak though.

Can you just go a little tighter on the connection?
