This plastic hexagon piece keeps coming loose and causing water to flow down the pipe under the sink. (lemmy.world)

It's happened twice now. I figure I maybe didn't tighten it enough last time so I went a bit harder this time. Any idea if something else might be wrong? My complete amateur theory is that the hard water buildup is making everything stiff down there, so that rotating the faucet also rotates this piece.

Thanks for your help!

Yes. Nylon tape on the threads of the cap. The "hexagon piece" is a plug and the hex is just there to give you something to tighten it with. Sometimes you see them with a recessed hex instead of an exposed one. Same function. The tape creates a seal the same way a gasket does.

Fantastic, thank you!
