Kohler Rialto One Piece Toilet Leaks


J

JoeC

Have a Kohler Rialto toilet that continuously drains water.
With the water supply turned off the entire tank drains overnight.
Replaced the Flush Valve (from Kohler)) , Seal (where the Flush Valve
mounts on the tank) and Flapper but still have the same problem.
So is there any that I can lose water other than past the Flapper or
the seal under the Flush Valve??

The Kohler in question is Gravity fed, not a Power-Lite.

Thanks for the interest.

Toilet leaks occur in two ways and are often very difficult to detect.
The most common toilet leak and often hardest to detect is caused by a
deteriorated or defected flush valve (flapper) ball at the bottom of
the toilet tank. If the flapper or ball valve does not seat properly
and form water tight, seal water will leak around it into the toilet
bowl. Often, this leak will occur without being heard. To test for this
type of leak, add a few drops of food color or place a colored dye
tablet (available from many hardware stores or possibly your water
utility) in the toilet after it has stopped filling. Do not flush the
toilet. Wait about twenty minutes: if the food coloring or dye appears
in the toilet bowl, the flapper/tank ball or drain seat is leaking and
needs to be replaced.

The second most-common type of leak is caused by an improperly adjusted
or broken fill (ball cock) valve. If the float is set too high or if
the shut-off valve fails to close completely, water will continue to
enter the tank and flow into the overflow tube. This type of leak can
be seen simply by taking the tank top off and observing if water is
flowing into the overflow tube once the tank is full.

I went through this drill a couple of years ago. Kohler maintained
(in one of our many telephone conversations) that regardless of what
data on the flapper valve said, I had to use one of theirs. They wound
up sending me, in bits and pieces, most of the guts to the unit.
Anyhow, it no longer leaks. If it starts again, it will be replaced
by a Toto.
Is the flapper seat clean, free of all garbage, etc?

Another, seldom-noticed defect occurs when you have hard water.
Deposits form on the bottom seal and causes the toilet to leak.
Replacing the flapper doesn't help. You can detect this simply by
running your finger around the bottom seal when there is no water in
the reservoir. If it feels rough, it needs to be fixed. The simplest
fix is to use a plastic scouring pad until it feels smooth. This
happens to one of our older (over 5 year) Kohlers.

FWIW, we have 3 fancy Kohlers in our home. 2 of them are constantly
screwing up. We also have one old-fashioned American Standard (5
gallon tank). That one and a Toto have never given us a bit of
trouble. When I finally get fed up with the Kohlers, they will surely
be replaced by Totos.

Hi Joe,

I too have a Rialto. I like the look and profile but hate the toilette. I
have replaced the Flapper twice in two years ...and they are not cheap. I
think its a poor flapper/seat issue and do not believe there are other
points where it leaks.

On top of that it's a constant clogger too.

Sorry I wish had more to offer in the way of help.

Kohler sent me a flapper for free. Be sure you get the chain adjusted
right. Just being off by one link will make it leak or fail to close.

I also agree about the clogging. We call this our "number one" toilet.

Oh, I was beginning to think I was being too critical of Kohler. I too have a leaking Rialto toilet. Changed all the suspected parts, still leaks. I have a suspicion that there is a cavity on the inside of the rim that lets a small amount of water constantly draining into the bowel. I filled the tank below the flapper valve and still leaks. Changed the feed tube and added silicone grease to make a good seal. I will get tired of this and go to a different brand soon.
