I'm trying to replace a tub drain, and as far as I can tell the replacement piece is the right size (same diameter and thread spacing, and nearly the same height as seen in pics)
However, whenver I attempt to screw in the new one, it always goes crooked (see third pic). Worse yet, it's now difficult to screw the old one back in, and I fear that my attempts may have affected the threads on the inside of the drain :-(
Does anyone have experience dealing with a similar situation or have any advice on solving it?
EDIT: adding photos of access panel behind tub. Not sure I can get the overflow water tight and the drain threaded in :-( still fiddling with it but it’s seeming impossible to get them both straight :-(
