Thanks Jim, that was a wonderful tip!

By the way, if it is NOT the seal of the flush valve (the rubber part)
or the washer that was leaking, where else could it be leaking? I've
looked at the toilet almost inside-out (too bad it's a one-piece toilet
so I couldn't disassemble it apart), but the only place that I could
identify that maybe it is leaking is the flush valve area (and the
three mysterious rubber washer thingy....

any idea? Thanks!


Yes, I agree with all that. If it does turn out to be
leaking around the valve or the 3 seals, maybe caulk those areas.
Use a hair dryer to thoroughly dry all the metal/china parts first.

Hi there, thanks for reading this thread.

I have a really old American Standard brand toilet, which is a
one-piece (made in 1935??) and you could see some photos of this toilet
at http://www.picturetrail.com/toilet2006/

This toilet has been leaking for a while (slow leak to the bowl), and
I'm suspecting that it is either the flush valve (the surface of the
disc and the brass valve) is not fully sealed, or it might be the three
tiny cone-shaped washer (something like this:
http://www.doityourself.com/invt/4244851#Specifications) that is just
too old and corrupted so the water simply sip through the washer area
(or the valve area). However, in our local plumbing supply store I
could only find American Standard #6 style of flush valve repair kit
(see
http://www.plumbingsupply.com/images...lve_47049.jpg),
instead of the #4 style (see
http://www.plumbingsupply.com/images...lve_47086.jpg), I
wonder if these two style of repair kit are interchanable?? The
diameter of the valve base of these two different styles seems to be
the same. Any comments? Thanks!


Ah, yes, the old Am Std "rocking boat" valve. Used thru the 60's,
I would guess.

http://www.doityourself.com/invt/4244851#Specifications
is a faucet washer "top hat". Does not apply.

I would be very hesitant about replacing the entire
valve seat assy on that toilet.
Some info here (may or may not help):

Do an experiment first. Remove the rubber disc and
"glue" (silicone sealant) it to the brass seat.
After it sets, fill tank and add food coloring or dye.
Watch for any sign of color in the bowl after
several hours. If there *is* leakage, then you
can attack the valve seat assy.
