Hi Dennis,
To minimize scale in the toilet system our
practice is to pump twelve times after the bowl
clears (while in flush mode). Swing to dry bowl
and pump a few more times if going sailing. I
believe this practice moves the uric acid out of the system.
We've had only minor scale issues a couple of
times in thirty years, including live-aboard for two years.
I have been meaning to do the vinegar soak but
never got around to it, however a maintenance
practice does include the occasional dollop of veggie oil pumped through.
Cheers, Russ

I finally swapped out the joker valve in
Touche's head because it was leaking
back. Didn't leak much. Just some of the
water between the bowl and the anti-siphon loop. Â
As usual, it had become scaled up. I threw the
old one in some vinegar and most of the scale
dissolved but the rubber was so distorted it was dumpster material.
I coated the new joker valve with TefGel hoping
to get more life out of it. I think Peggy
Hall, the head mistress recommends Super Lube for heads.Â
Also, I read that throwing some vinegar in the
head routinely minimizes scale build up.
This really isn't a big thing for me. I get
the valves wholesale for under $10 and changing
one is only a 10 minute job. But I'd sure like to skip it altogether.
Any other tricks?
