I'm doing the plumbing on my new tank, and I've got 3/4 threaded bulkheads for the return. The outside of the bulkhead is also threaded, and I realized it fits my 1 inch union. Could I glue a 3/4 elbow inside the 1 inch union, or would there end up being a chance of leaking since theres a little bit of a gap? I'm figuring that once the cement is in there it should seal, just want to make sure. Itd make maintaining the pipes a dream because I could then disconnect the entirety of the plumbing system from the tank.
