 leak at bottom of cap
Author: curmudgeon (OR)

No cartridge, but no other forum seems as appropriate. Delta 1900 kitchen faucet (1970s vintage), but never mentioned online by that name, even by Delta. You can find the exploded diagram at [homeappliance.manualsonline.com]

It was becoming impossible to shut the water off.

I had replaced the ball over a year ago, and noticed at the time that the plastic adjustment ring on the cap (for some reason not specified on the diagram) looked a bit buggered up.

I installed new O-rings, springs & caps, and replaced the adjusting ring with a new one made of brass. I greased everything greasable in this process. Now I have it reassembled. I have turned the cap as tight as I can, and the adjustment ring as far as seems possible without rendering the handle immobile. I still get leaking from the bottom of the cap.

I am now at the point where I need advice from someone better than I at plumbing.

PS I noticed an ad for pre-1976 springs & caps, and have ordered them, but they won't be here for a week.

Can the replacement parts I got be at fault?

The cap on the right side doesn't seem to seat as well as its mate.
