Slow shower head drip from a KOHLER 8304-K-NA Valve Body

in THE MAIN WALL

Woke up this morning to a slow drip on a 2 year old valve body. Had a spare cartridge and swapped in after cleaning the valve body and lubing built in o-rings with petroleum jelly.

Still have the slow drip. Inspected the valve body interior, all looked clean, no pitting.

Any suggestions?

    look at where the o-rings seal. I think that kohler cartridges have been ceramic for decades so the part that is going to leak is the seals to the ceramic parts.

    I initially thought it was a leaking o-ring but notice the valve will leak with unless both supplies are shut off

    Must be leaking through the cartridge somehow but is odd that two cartridges are doing same thing.

    I may just order a new cartridge since both of the current unit are previously used.

    most of those o-rings don't like to seal again after they have been in service for a while and have hardened in that position if you try to disassemble and reassemble them
