    Default problems with kohler Rite-Temp shower valve

    Our shower developed a steady drip from the faucet. I opened up the shower control, removed the K-304-KS Rite-Temp™ Pressure-balancing Valve with Screwdriver Stops. Bought a new one (a mere $96!) and replaced it - as far as I can tell, according to instructions. Now, when I turn the water back on, it's not possible to stop the flow of water completely - there's a high pitched whine from the hot water side, and now there's dripping from the pressure balancng unit itself. The folks at the plumbing supply place were no help whatsoever... any suggestions out there?

    Talking kohler nightmares

    Kohler is a very poor quality faucet and is usually very hard to get parts forin a timely manner. The more age on the faucet , the harder it is to find the style and parts... their repair parts book is as large as the phone book

    You are lucky that they acutally have the parts in stock in the first place..

    take the part ouit and try to get another one from that store, it couild be defective .....

    if that dont work, call a plumber and ask their opinion,

    most likely they will tell you a that your best bet for only $150 is to change the whole thing out and install a DELTA 1700 pressure balanced faucet....

    if you are up to the task, and it is feasalbe,
    take the 96 buck part back and excahane it for the Delta 1700


    good luck

    Angry Further Kohler headaches

    Called Kohler and they sent an other replacement part - after many apologies and saying that the part is free due to "guarantee" -- well it arrived after 10 days... I put it in and although water doesn't leak from the valve itself, it's still not possible to completely shut the hot water off, once it's on. I think I'll give Kohler one more chance with a replacement part - these parts must be absolute junk!! I think they're emphasizing faucet styles and appearance more than quality

    I've done 2 of those in my 2 bathrooms (1 stall, 1 tub) in the last 6 months and they both worked fine out of the box. Can I assume you removed the stop gaskets during the sweating of the connections?

    Default Same problem -- figured it out (I think)

    Hi,

    I had exactly the same problem with my kohler valve and pressure regulator. It was dripping dripping dripping. Went to the plumbing store (crest supply in san carlos ca) and got a new pair ($75 for both--the pressure regulator and the "black cap").

    When I put the new valve and regulatory in, everything seemed fine. Turned on the water, adjusted the rite-temp to make sure I don't get scalded. Thought I was done.

    Then about 20 minutes later when I flushed a toilet in the house, the shower suddenly went on and it had a high pitched whining sound. And I couldn't shut off the water anymore on the shower!!!

    I read the instructions again and I think I figured out the problem: I put the (white) spacers between the body and the "black cap" (as the instructions seem to imply). After I removed the white spacers and re-installed, then it is working perfectly! I think the reason is that the whole contraption works by making sure the black cap is squeezed enough in against the pressure regulator. If not, then water can "squeeze" through some of the o-rings (especially in the black cap). It's actually pretty weird design!!! It's all based on friction, it looks like.

    Hope that helps.
    ps: Don't forget to put the steel plate on the "black cap" so the screws don't go directly against the plastic. I wish the instructions were in color (instead of black and white) so I could tell this! If you look carefully at the drawing, the steel plate is drawn in there but not mentioned!

    Default

    My rite-temp started leaking after 5 years. I see that the valve cap can be replaced, but it's not clear that this will fix it. Has anyone had any luck "rebuilding" one of these, i.e. replacing the o-rings, etc?

    Also, someone mentioned replacing the whole thing with a Delta 1700? Is this assuming I have access to sweat in a new unit or does this fit into the Kohler body? My shower is on an outside will, so my only access is through the tile.

    Thanks
    Jerry
