Groco model K head seal leaking -- winterization?
My Groco model K toilet (with electric drive) is leaking around the
shaft seal. I've rebuilt the darn thing twice in two years, taking 6 hours and about $100 for the kit. Why does it leak? When I winterize it I pumped pink antifreeze (propylene glycol, I think) through the head, the lines, and into the holding tank, then pumped out the holding tank. Any idea if this created the problem? Any other causes? Bob Hargraves |
