View Full Version : Old Kohler leak problem

Hi all,
amateur plumbing alert!
My house which was built in the 50s but had a remodel in the 70s has an old Kohler single-handle shower. By digging around the internet I finally backed out that I've got a "Rite-temp" pressure balance faucet from 1973 or so. The problem I was up against is that the water doesn't shut off completely anymore, so I took everything apart and found a valve rebuild kit through some miracle (these ones (http://www.google.com/products?q=KOHLER+(78579)&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&sa=X&oi=product_result_group&resnum=1&ct=title)) and swapped all the parts out, hoping the new washers would be the end of it. Alas, the water still doesn't turn off, and in fact it flows even more freely, almost at 1/4 pressure even with the handle cranked off. The valve itself is working fine in the sense that when you turn the shower on, it starts cold, mixes in the hot at the right time, and stops where the collars says to to prevent scalding, exactly as it was before I was messing around, but I have to turn off the valves in the access panel after a shower to get the water all the way off! What should my first step be to figure out why?

You need to replace the pressure balancing unit. It's cracked!

Well isn't that just my luck! Thanks for the answer. How do you get those buggers out? I didn't see any more obvious screws after I had all the pistons and cartridge and stem and all that nonsense out of it! I've taken the thing apart so many times now I think i could do it blindfolded at least

You pull it out, and that is the only thing I have ever found that causes a leak with that valve.
