I have recently notice that my water key cork does not cover the hole at the bottom of the slide entirely, do I need a new cork, or is it out of alignment.

It could be both...
Nobody can tell you without photos, I think.

Yesterday I took a older King in to repair with the same problem, a cup that doesn't align perfectly with the nipple (apologies for wrong technical terms?) and a pad that needs changing.

The tech said no way he could bend the key without risking breaking it, but he could put a new pad on that would seal. Charged me $2.12 USD.

I guess I could order a new key that might fit. And then when I go to change it the spring will fly across the room and be lost forever, and I'll order a new spring. By the time it comes I'll have forgotten where I put the key. Maybe I'll just live with watching the pad closely and changing when it stops sealing.

Anyway, I suspect that cups that don't meet the nipple squarely are fairly common.

A scrap piece of sheet brass to protect the waterkey from marring, and a pair or two of quality parallel jaw pliers can fix the majority of waterkey issues. Unless, of course, it was installed incorrectly.

Proceed at your own risk.

All it takes is a light bump to cause that misalignment. The water key is sometimes made of soft metal and bends easily.
