Why does my kohler shower valve drip after installing repair kit?

I have done this several times,sometimes it will work for a month or two,sometimes it starts dripping in a day or two.|||you have to carefully observe the repair. another reason could be


debris lodged in the water supply side to the shower valves.


Turn of the water remove the guts rubber seats and springs hold


a bucket or a plastic pan to divert the water down into the tub and


have some one turn the water on quickly and then turn it of just as fast.


Put a washcloth in the tub drain so you won't lose any parts you


didn't see when the water blows itself out of the valve body. Something comes


out your in luck , just put it back together and voila no leaks. Now if it has to


do with the valve body itself look for sharp edges or broken areas of plastic


or metal where the valve mechanism will find it's home. These little snags


can often rag out a valve seat or spring in no time at all. Clean these


surfaces up if you can. If they are the old type valve stems check the


washer surface for cuts or flattening, and then check if you see this situation


the actual valve seat for damage. No problems put it back together make sure you


replace any springs or seats observe if any o-ring seals are missing


replace them if necessary, put it back together and your good as gold.
