Having a problem with a shower valve that is leaking. I contacted Kohler
and got replacement o-rings for the pressure regulator and a new plastic
valve and installed based on their recommendation. This did not correct the
problem however which leaves me wondering what it could be. I'm losing
about three gallons a day.
I did notice that inside the brass body that houses the regulator, the brass
connections that meet with the o-rings on the plastic pressure regulator
seemed to have corroded slightly. Can they be cleaned with an abrasive or
should they be left alone? Could this be the problem?

What was the part number of the "new plastic valve"?
I generally recommend replacing both the control valve and pressure balancing
unit at the same time
Never use anything abrasive on a sealing surface like that. One minor change
in the profile surface could really mess you up>
Clean only with plain white vinegar....(soak a rag and stick it inside the
valve body for a couple of hours)
Plastic Valve is really called a mixer cap. Part number is 77759.
Thanks for the info - I'm going to get a hold of the press bal unit and
Incidently, I have a second shower in this house doing the exact same thing
(newly purchased house). Is this normal for Kohler rite-temp fixtures or am
I just unlucky?

"Newly purchased" doesn't really mean much. How old are the valves?
The first thing I'd do, before considering how lucky you are, is find out how
high your static water pressure is over a 24 hour period. Anything over 60 PSI
is more than you need, and will contribute to shortened life spans of some
I used "Newly purchased" because its new to me but not a new house. I
believe the previous owners renovated the bathrooms within the last 6 years
but basically I don't know how old the valves are.
I'll get the static pressure checked.
