The lesser kitchen faucet began dribbling and required replacement, as there are no user serviceable parts within. One of the 3D printed adapters I built during the previous iteration had disintegrated:
The new faucet came with a somewhat different baseplate and I managed to conjure a firm, sealed mount from the various parts without further construction.
The nicely curved brass snout is the third in my collection. Surely they’ll come in handy for something!
While I was in a plumbing state of mind, I again replaced the spout O-rings in the never-sufficiently-to-be-damned American Standard Elite (hah!) faucet, as it was also dribbling.
This time, I used oxalic acid to remove the assorted scale and crud inside the spout. It seemed to be more effective than the usual white vinegar, although nothing seems to preserve the O-rings.
