Bathroom Sink Stopper Rod

After swapping the corroded steel rod end-for-end twice, I expected this would happen:

So now we know a chrome-plated steel rod will survive 16 years in a bathroom drain, at least if you’re willing to coddle the fool thing far more than seems reasonable.

I eased a slug of epoxy into the brass tube to seal the wet end. Given how little use the stopper gets, I hope it lasts forever …

    I used to have a really old house that used chrome plated brass for the popups, [sigh]. We replaced a steel-chrome set when we redid faucets around 5 years ago. The new sets have lots of plastic in the working parts (FRP stems for the valves, generic but sturdy plastic below the deck) so they’re resistant to anything I’ll put down our sinks. (Our water has both carbonate and sulfate components, so that’s a plus.)

    The popup mechanism is interesting. The handle runs a linear-to-rotary cam, and a torsion bowden-type cable connects to the popup cam. Various splines give the option for fine tuning, but the absence of any corrodables in the drain is a big plus. I have to degunk the main bathroom sinks twice a year, and beyond having to keep track of the small popup cam and its retaining piece, it’s easy. I was impressed.

      Despite my kvetching about engineering plastics, keeping metal away from electrolyte-filled water is always a Good Idea. In your situation, it’s essential.

      But all those doodads for a drain popup can’t possibly last for two decades!

        Agreed. Fortunately, two of the 3 sinks don’t use the popup that much. The FRP stems needed extra lubrication for a couple of years until things wore in.

        The American Standard faucet sets replaced Delta one-handled faucets and drains. The drain popup was going fairly well, even after 12 years, but the seals and valves in the faucet were a nightmare. Home Depot has the rebuild kits in stock–lots of them… FWIW, if I had to go one-handled again, I’d go back to Moen.
