A few years back I replumbed the shower using a Kohler K-303-K-NA 3-handle diverter valve.
Pulling the center diverter knob has always resulted in a notable KLUNK noise, and water reliably flows to the shower head.
Recently however I've lost pressure to a dribble. When I pull on the diverter knob, I'll get full pressure initially, but then within a second or so there's a softer THUNK noise from the diverter knob, and the water quickly tapers down.
I don't see a rebuild kit for the faucet, but Kohler does list individual spare parts. There are a couple of O-rings and washers, a seat, a spring, and of course the diverter body. Is there a suspect part I should be looking for here? I haven't cracked it open yet, hoping it's something obvious like a sliced O-ring or corroded spring.
