Kohler lowboy toilet seat does not have bolts underneath
I have the same low boy where the bolts are inside the hollow body of the toilet. I called Kohler customer service and was told to use brute force to yank the toilet seat out. My husband suggested using a saw to cut the bolt but he hasn't done it yet. He wants to replace all our Kohler low boys which constantly leak becos of poor design of handle and flapper. The handle pulls the flapper slightly to the side when you flush. And the flapper lip being a tiny bit too small, if it doesn't sit just right, the toilet leaks. We've replaced one already with a Toto and love it. Too bad that Kohler isn't trying to fix the problem as I see many many online posts with the same problem and recommendation to replace the Kohler with Toto or somethng else.
Water is leaking into the toilet
Take a close look at the Geberit TM seal...mine had air bubbles in it that prevented a flush seal...and heance a slow leak that caused it to fill-up many times a day and night...see my issue here: https://pierrebridge.wixsite.com/fixit.
Kohler toilet leave black streaks and small black particles coming out of water holes under toilet bowl rim.
#K4421 Re black specks coming from rim jets (only). Me too. Looks like bits of rotting rubber. Water in tank is clear-no specks there. I suspect the small hose from fill valve to top of flush piston may be breaking down, as it has gone rigid and I'm afraid to squeeze it lest it shatter. First thing I'll try is replacing that hose, if I can find one. My daughter has same toilet but no "specks". With her toilet, it's the same small hose but the problem is it occasionally pops off at fill valve end. I can fix that with wire but when I find hose source, I'll buy two.
